| # Team Members - Zhirong Chen (zhirong4) - Xiaoyang Chu (xzhu458) - Zicheng Ma (zma17) - Dongshen Ye (dye7) # Problem Students residing in residential colleges at the IZJU campus encounter issues when they inadvertently lock their ID cards inside their dormitories, particularly after showering at night. These students require a temporary IC card that exclusively grants access to their dormitory doors. However, staff availability is limited late at night to issue such IC cards. Consequently, an automated IC card dispenser is necessary to provide temporary IC cards to students. # Solution Overview The automated IC card dispenser system will authenticate students’ identities by scanning QR codes on their cell phones. Upon identity verification, the system's embedded software will retrieve the student's dormitory details. Subsequently, the mechanical system will select an IC card, program it with access information, and dispense it. Concurrently, the system will log the borrower's details. Once students return the temporary IC cards, the mechanical system will retrieve them, erase the stored data, and the software will log the cards as returned. # Solution Components ## KIOSK Software The software will encompass the user interface (UI), interaction with the central server, and integration with the recycling mechanical system. ## Recycling Mechanical System The recycling mechanical system will comprise a card storage box, a conveyance system for card transportation from the storage box to the reading and exit points, and an IC card reader/writer. ## Web User Interface The web user interface will facilitate interactions between users and administrators. Users can authenticate via the interface, while administrators can monitor terminal status and exercise remote control. ## Server System The backend software will be responsible for user authentication and authorizing the terminal to issue a new card. # Criteria for Success Robustness: The system should operate continuously 24x7 without significant issues or maintenance requirements. The recycling system's error rate should not exceed 1/500, and the system must detect errors and notify administrators promptly. Efficiency: The system should handle user requests swiftly and effectively. Security: Data transmission between terminals and the server must be secure and resistant to prevalent hacking techniques. Compatibility: The system should be compatible with existing authorization and access control systems. # Distribution of Work Zhirong Chen Design the backend server software system.

Traditional systems struggle with dynamically managing power supply due to changing user demands and device requirements, often leading to energy waste and inconsistent device functionality. Our solution is a dynamic power management system that intelligently adapts voltage supply in real-time, responding to user interactions like switching devices or manual power generation. This project aims to demonstrate the practicality of smart power management in real-world scenarios, offering an accessible and engaging illustration of these principles for a broad audience. # SOLUTION OVERVIEW Our smart routing system manages and stores energy from electrical outlets and manual inputs — such as hand-crank generators and a pneumatic turbine — into a battery. After receiving power information from the sensor, it then dynamically allocates power to a fan and lightbulb in response to user interactions. The system's adaptability is managed by a microcontroller, which ensures efficient energy distribution and maintains device operation through variable conditions. # SOLUTION COMPONENTS ## SUBSYSTEM 1: Energy Harvesting and Storage This subsystem combines power from electrical sockets and manual energy generation methods, storing it in a battery for stable supply. It utilizes hand-crank generators and a pneumatic turbine, powered by a hand-squeezed air pump, to capture and convert mechanical energy into electrical energy. Diodes and charge controllers ensure efficient energy flow into the battery, safeguarding against overcharging and power backflow. ## SUBSYSTEM 2: User Interaction Interface Switches and buttons serve as physical input devices. This user interaction interface captures user inputs, such as toggling the state of the socket, light, and fan, or activating the hand generator and turbine. ## SUBSYSTEM 3: Power Sensing and Load Management The power requirements of the fan and lightbulb are constantly monitored by current sensors, informing the microcontroller of any fluctuations in power consumption. This data allows the system to adjust power distribution in real-time, maintaining an uninterrupted operation of the connected devices. ## SUBSYSTEM 4: Microcontroller and Power Adjustment A microcontroller serves as the brain of the operation, processing sensor inputs and user interactions to manage the power flow effectively. It commands solid-state relays or transistor-based circuits to regulate the power supplied to the fan and lightbulb, ensuring their continuous operation. ## SUBSYSTEM 5: Display and Monitoring An LED screen displays battery storage condition and real-time power usage for both the fan and lightbulb, providing a visual representation of the system’s efficiency and the power dynamics between the devices and the power sources. # CRITERION FOR SUCCESS - Reliability: The system should consistently provide uninterrupted power to both the fan and the lightbulb regardless of user interactions, such as turning switches on and off and the presence of manual power generation from hand cranks or turbine inputs. - Efficiency: It should maximize the energy harvested from manual inputs and minimize losses during power conversion and distribution. - Good Visualization: The project should successfully demonstrate the principles of smart power routing in a way that is understandable and engaging for viewers, with clear displays of current power and battery condition. - Safety: The energy storage and distribution system must operate safely at all times, with built-in safeguards against overcharging, power backflow, and other potential hazards. - Durability and Maintenance: The system should be built to last, with easy maintenance and robust construction to withstand frequent use, especially by those unfamiliar with the system. # DESTRIBUTION OF WORK ## Yunfei Lyu - Project Manager and Quality Assurance - Responsibilities: Yunfei will oversee the project as the manager, coordinating project timelines, resource distribution, and team communication. Yunfei is also tasked with ensuring the overall quality of the project, focusing on both hardware and software components to meet the established reliability and safety standards. ## Jingjing Qiu - Software Development - Responsibilities: Jingjing will be responsible for developing the control software and energy management algorithm. The role involves coding the software to process input signals and dynamically adjust outputs, as well as implementing data logging capabilities. ## Jiabao Shen - Hardware Design and Safety Concerns - Responsibilities: Jiabao will spearhead the design and assembly of the hardware components, which includes crafting a smart voltage regulation system and ensuring the hardware is durable and easy to maintain. Additionally, Jiabao will be responsible for integrating safety features such as circuit breakers and surge protectors. ## Xiaoyi Han - User Interface and Interaction - Responsibilities: Xiaoyi's focus will be on enhancing user experience by developing an intuitive user interface (if applicable) and ensuring that the functional demonstration table is user-friendly and engaging.

| ## Team members Haoze Gao, haozeg2 Haowen Zheng, haowenz5 Qiran Pan, qiranp2 Yiheng Zhang, yihengz5 ## Title Of Project AR Sandbox Redesign ## Problem Introducing a smart sandbox with augmented reality (AR) capabilities that projects contour maps in real-time onto the sand surface, making geography education for children not only informative but also significantly more enjoyable. However, currently available educational sandboxes are mostly cumbersome and limited to public spaces like activity centers rather than serving as personalized learning tools. Furthermore, the existing AR projectors designed for sandboxes exhibit primitive features, characterized by a notably low refresh rate and harsh direct light. We are committed to addressing these drawbacks and are working towards the development of a new and improved AR sandbox. This innovative solution aims to overcome the limitations of bulkiness, offering a more accessible and personal learning experience. Additionally, we are focused on enhancing the AR functionality to deliver a smoother experience with higher refresh rates and reduced glare, ensuring a more comfortable and engaging educational tool for children. ## Solution Overview We would develop a next-generation sandbox with augmented reality (AR) projection and interaction capabilities. In comparison to the popular versions available in the market, our AR projector is set to achieve a higher refresh rate, easier control without external touch screen, and the overall structure will be designed to be foldable while ensuring both high load-bearing capacity and stability. ## Solution Components ### Sensor Subsystem - **RGBD** camera (ToF or structured light) and associated software for acquiring RGB image and processing depth information ### Processing Subsystem With the use of GPU acceleration - **Human body detection** to overcome the interference from human hands and head. With this to enable multi-user collaboration - **User Interface** with gesture control. Use hand gestures to interact with the screen projected on sand. - **Real-time topography rendering**: Constructing topography map from depth information with GPU acceleration ### Display Subsystem - Displaying on sand requires high luminance projector and associated **calibration software**. The software needs to track for image alignment ### Structure Subsystem - The sand table should be made of materials and designs with sufficient strength to carry sand and prevent people from damaging the wall of the sand table when in use. - The sand table will be foldable, which will reduce the volume and facilitate carrying and storage. - The sand table can be separated from the sand while folding, which will make the sand table more conducive to cleaning, increasing durability, and conducive to rapid deployment in different use scenarios. - We will add an additional vibration device so that the sand surface can be quickly restored to level when necessary. ## Criterion For Success For our criteria for success, we outline the following requirements: 1. Physical Structure: The sandbox must have a robust physical structure capable of fully supporting the weight of the sand without any leakage. It should also withstand lateral forces of around 40kg exerted by children pulling on the sides of the sandbox. 2. AR Projector: The projector should be capable of accurately projecting contour maps onto the sandbox with more than 1 people playing with sand at a refresh rate of higher than 30fps. To verify the correctness of the contour maps, we will artificially create distinctive landforms such as ridges, valleys, and saddles, and compare them with the projected contour maps to ensure accurate alignment. |

| # Team Members Xiangmei Chen [xc47] Peiqi Cai [peiqic3] Yang Dai [yangdai2] Lumeng Xu [lumengx2] # Title Actions to Mosquitoes # Problem Many of us get bitten by mosquitoes without notice. We come up with a device that can distinguish by sound whether a mosquito exist in a given area and take actions to keep it away. Solutions existing in the market include mosquito spray, insect-repelling lamp, and mosquito-repellent incense. However, they work continuously, and people may get uncomfortable with its smell. It would be less disturbing and resource saving if the device only reacts when a mosquito approaches. # Solution Overview In order to have in-time response of mosquitoes, we first need a device to detect sounds of mosquitoes. After the sound is collected, we need to process the signal to tell if a mosquito presents. If the presence is true, an actuator will take actions to keep the mosquitoes away. # Solution Components [Sound Detecting Subsystem] A sound detecting device, could be high accuracy microphone that can capture the sound of mosquitoes since they produce a characteristic buzzing sound when they fly, which varies depending on the species and gender. The frequency of the sound that the system capturing can be set to the range of frequencies of the mosquitoes to further improve accuracy. [Signal Processing Subsystem] A signal processor that can analyze the sound and identify the presence and type of mosquitoes. The signal processor could use a machine learning or other algorithms, or a frequency filter to distinguish the mosquito sound from other noises. [Mechanical Subsystem] An actuator that can take actions to keep the mosquitoes away. Depending on the desired effect, the actuator could emit a high-frequency sound that repels mosquitoes, a chemical spray that kills or deters them, or a device that could emit gas or light of specific wavelength that attract them and knock them down. # Criterion for Success Detection Accuracy: The device should be able to accurately detect the distinctive sound of mosquito wings flapping with a high degree of precision to minimize false positives (e.g., from other insects or ambient noise) and false negatives (failure to detect mosquitoes). Responsiveness: Upon detecting a mosquito, the device should promptly activate the mechanical components to deter or eliminate the mosquito within a predefined time frame, ensuring efficient protection. Coverage Area: The device must effectively monitor and protect a defined area, such as a standard-sized room, from mosquitoes, with clear specifications on its effective range. User Interface: If applicable, any software interface for the device should be user-friendly and allow users to easily adjust settings, such as detection sensitivity or deterrent mechanisms. Energy Efficiency: The device should operate efficiently, using a reasonable amount of power, and if battery-operated, should have a battery life that is practical for typical use cases (e.g., overnight use in a residential setting). Safety: The device and its deterrent methods (such as acoustic waves or mosquito sprays) should be safe for use in the intended environment, not posing health risks to humans or pets. # Distribution of Work Peiqi Cai [EE]: Responsible for the design and implementation of the microphone array and any other necessary sensors that are part of the hardware which collects the mosquito sounds. This will include circuit design, component selection, and integration of the sensors with the rest of the system. Lumeng Xu [ECE]: Develop the signal processing software that analyzes the audio data from the hardware to distinguish mosquito sounds. This includes writing the algorithm, possibly utilizing machine learning, and ensuring it can run efficiently in real-time. Yang Dai [ECE]: In charge of the overall system integration, ensuring that the hardware and software components communicate effectively. This student will also be responsible for the user interface, if applicable, and making sure that the software is user-friendly and robust. Xiangmei Chen [ME]: Design and test the mechanical components that take action to repel or eliminate mosquitoes. This could involve the design of the enclosure that houses the electronics, any moving parts for the actuation mechanism, and the dispersion system for the repellent if a spray is used. She will also ensure that the physical design adheres to safety and ergonomic standards. |

| # TEAM MEMBERS - Qirong Xia (qirongx2) - Kejia Hu (kejiahu2) - Qianhe Ye (qianhey2) - Zhuohao Li (zhuohao5) # PROBLEM Many physical systems involve interactions between multiple variables that can be difficult to conceptualize in a 2D space. Visualizing these solutions in 3D allows a more intuitive understanding of the behavior over time or across different conditions. Additionally, for problems involving spatial dimensions, a 3D visualization can illustrate how variables change not just over time but also across different points in space. # SOLUTION OVERVIEW Our project aims to create a 3D real-time visualization of a time-varying 2D Ordinary Differential Equation (ODE) function. This visualization platform will dynamically represent the changing behavior of the function over time. Additionally, we will project the color to the surface from either the top or below, adding another dimension of visual interpretation. Our design has three subsystems and one optional subsystem. The **User Interface module** will get the ODE from the user calculate the solution for it and transmit the data to the Dynamic Stick Control module. This subsystem will get the ODE solution from the User Interface Module and then convert the information to languages that the mechanical devices can understand. Our **Mechanical module** adjusts the height of the stick based on the signal transmitted from the Dynamic Stick Control module. Additionally, this module will use a **Lycra fabric** to cover the top of the grid-like sticks to create a smooth visualization surface for displaying the ODE. Finally, if the time is available, we will design a Surface Coloring and Projection Module which will project images to the canvas either from the top or below. # SOLUTION COMPONENTS ## USER INTERFACE SUBSYSTEM The User Interface (UI) module serves as the interface between the user and the ODE visualization system. It receives input ODE equations from the user, calculates the solution for them, and transmits the data to the Dynamic Stick Control module for visualization. To realize this function, firstly, we need a Graphical User Interface (GUI) which contains components such as text input fields, buttons, sliders, and dropdown menus for user interaction, allowing users to input ODE equations through a graphical interface. Secondly, once the user inputs the ODE equations, the module utilizes an ODE solver algorithm to compute the solution. This may involve numerical integration techniques such as Euler's method, Runge-Kutta method, or other numerical approaches depending on the complexity and accuracy requirements of the ODE. Thirdly, after computing the solution, the UI module transmits the data, including the time-varying solutions of the ODE variables, to the Dynamic Stick Control module for visualization. The transmission occurs through a wired communication interface. Lastly, the UI module will provide feedback to the user regarding the status of the computation, such as progress indicators or error messages in case of invalid input or computation failures. ## DYNAMIC-STICK CONTROL SUBSYSTEM The control subsystem first interprets the solution of ODE from the User Interface subsystem. Then the system translates the solutions of the ODE into control commands that can be executed by the mechanical subsystem. This involves mapping the mathematical solutions to physical actions, such as the movement of the sticks. Besides this, the control subsystem also gets feedback from the mechanical subsystem, comparing the actual outcomes with the desired outcomes, and tuning the outputs accordingly. To implement the control logic, we plan to use the Arduino development board or an low-power Intel FPGA (DE10-Lite). ## MECHANICAL SUBSYSTEM The mechanical subsystem is composed of sticks that can dynamically move up and down based on the displayed solution. Lycra fabric is affixed to the top of each stick to make the visualization smooth. The mechanical subsystem gets inputs from the control subsystem, performing the actions as dictated by the control commands, and feedback to the control subsystem for further tuning. The system maintains the precision and accuracy of the motions by following the control commands from the control system as closely as possible. It should also be robust and minimize the small vibrations and noise from the environment. ## SURFACE COLORING AND PROJECTION SUBSYSTEM (OPTIONAL) The coloring and projection subsystem is on the top of the device. It continuously measures the height of each stick in real-time, which can be achieved by incorporating ultrasonic sensors in the subsystem to sense the distance. To achieve accurate and rapid coloring, the subsystem also needs to prevent noise from affecting the sensor's operation. The data collected from the sensors is processed to identify the status of the mechanical system. Given the processed sensing data, the subsystem employs a logic to assign colors based on the height of the sticks. For example, the highest sticks could be assigned to the color red, while the saddle points are assigned to the color blue. As the height of the sticks changes, the subsystem must dynamically adjust the projections in real time to reflect these changes. We plan to implement this feature if time is available since it requires an independent control system to implement the logic. # Criterion for Success The success of our project will be determined by the following high-level goals: 1. **Functional User Interface (UI) Subsystem**: The UI should be intuitive and user-friendly, allowing users to input ODE equations easily and see the status of computations. It should effectively communicate with the Dynamic Stick Control subsystem to transmit ODE solutions accurately and efficiently. 2. **Accurate Dynamic-Stick Control Subsystem**: This subsystem needs to accurately interpret and translate ODE solutions into precise mechanical movements. The control system, whether using an Arduino or FPGA, should provide reliable and real-time response to the computations received from the UI. 3. **Robust Mechanical Subsystem**: The mechanical setup, involving the dynamic sticks and Lycra fabric, must respond accurately to the control signals. It should be sturdy, minimize vibrations and noise, and accurately reflect the ODE solutions in a 3D format. 4. **Overall Integration and Performance**: All subsystems must work harmoniously to create a seamless and real-time 3D visualization of the ODE solutions. The system should be stable, efficient, and provide a clear and accurate representation of the ODE dynamics. # Distribution of Work The work distribution among team members is planned as follows, considering their majors and skills: - **Qirong Xia (qirongx2)**:As an electrical engineering student, Qirong will lead the electrical design and, if time allows, lead the development of the Surface Coloring and Projection subsystem, focusing on sensor integration and real-time color projection. - **Kejia Hu (kejiahu2)**: With expertise in electrical engineering, Kejia will be responsible for the Dynamic-Stick Control subsystem, including programming the Arduino or FPGA for accurate control and feedback mechanisms. - **Qianhe Ye (qianhey2)**: As a mechanical engineering student, Qianhe will lead the design and construction of the Mechanical subsystem, ensuring the precision and robustness of the stick movements and fabric setup. - **Zhuohao Li (zhuohao5)**: With a background in computer engineering, Zhuohao will focus on developing the User Interface subsystem, including the GUI design and integration with the ODE solver algorithm. The project's complexity is justified by the diverse skills of the team members. The combination of expertise in computer, electrical, and mechanical engineering is essential for tackling the various challenges presented by this interdisciplinary project. Each member's skill set is aligned with their respective subsystem, ensuring a well-rounded approach to achieving the project's goals. |

| **Team Member (NetId)** - Ximo Wang (ximow2) - Yanbing Yang (yanbing7) - Yang Chen (yangc7) - Yuzheng Zhu (yz83) **Problem** We are going to design and realize an airway delivery system with drone, container and cloud server. Delivery of light weight, medium range, fast response with a city is a strong demand especially during rush hour. Traditional airway delivery drones with GPS guiding are not precise enough for landing in limited space. Existing delivery drones on market requires the manual operation during picking and placing the goods. **Solution Overview** The basic parts of our solution are delivery drone and automatic containers. The drone can communicate with container to fetch the delivery information while picking up goods. An app connects the container, cloud server and costumer is designed as well. **Solution Components (Also Distribution of Work)** - Light Delivery Drone (Yanbing) Design and manufacture a quadrotor UAV with special structure for transition between picking-up mode and shipping mode. The drone will realize the function of self-navigation, precise landing, automatic obstacle avoidance, RTK communication and cloud server connection. - Navigation System with RTK (Ximo) Real-Time Kinematics operates by augmenting the standard Global Navigation Satellite System positioning technique with real-time correction data. The device applies corrections to its own GNSS calculations, resulting in highly accurate positioning with centimeter-level precision. Using this method, our UAV can find the accurate position of container when landing. - Automatic Container (Yuzheng) The container needs to interface with the drone, responsible for automatically storing objects delivered to the landing pad by the drone into the container. It also handles transporting goods placed in the locker by the merchant to the landing pad for the drone to pick up and deliver. - Communication System (Yang) Our drone needs to communicate with both container and cloud. In this way, user can send delivery request and know the progress of the delivery, even the current location of the drone. The container would also know the status of the drone and resend message if possible. **Criterion for Success** Our solution can accurately deliver the requested good from one location to the destination without manual operations. The drone can pick up the package and deliver it to the destination independently. What the user needs to do is just put the package into the container and get their package from the container. **Alternatives** Foodpanda has piloted food deliveries in Singapore using multirotor drones from ST Engineering and in Pakistan using VTOL drones from Woot Tech. Flytrex has delivered over 55K orders by drone in three towns in North Carolina and Texas since 2022, including Starbucks coffee, Walmart, Chick-fil-A, Papa John's pizza and more. Our solution differs from existing solutions since it’s more convenient and cheaper. The drone and the delivery container are integrated, with the container serving both as a storage unit and a landing pad. Both merchants and customers need only to concentrate on the order itself. Placing an order through the program is all that's required, as all decision-making, delivery, and interfacing are fully automated. We use low-cost standard components to reduce expenses. |

| Spring 2024 ECE445 RFA Image acquisition, 3D reconstruction and a visual interactive digital heritage system # TEAM MEMBERS: - Qianyan Shen (qianyan2) - Ziying Li (ziyingl4) - Chuanrui Chen (cc86) - Denglin Cheng (denglin3) # Problem Cultural artifacts possess significant historical, cultural, and artistic value. However, due to the passage of time and the impact of natural deterioration, many artifacts face risks of damage, loss, or decay. Additionally, for history enthusiasts and researchers worldwide, detailed information about specific artifacts is not readily accessible. Traditional photographs often fail to capture the intricate details of artifacts, hampering comprehensive research and preservation efforts. Furthermore, the absence of user-friendly interactive interfaces limits the interaction between enthusiasts and artifacts, impeding immersive experiences in virtual exploration of cultural heritage. Therefore, our team aims to develop a system that can generate realistic 3D models of cultural artifacts and provide users with a user-friendly interactive interface for immersive exploration. # Solution Overview Our system will use advanced scanning and 3D reconstruction techniques to capture the detailed geometry of cultural artifacts. This will be achieved through a series of subsystems including a Stabilized Scanning Subsystem, 3D Reconstruction Subsystem, Database Subsystem, and Interactive Interface Subsystem. Please refer to the following subsystem descriptions for more detailed information. # Solution Components ## Stabilized Scanning Subsystem This subsystem aims to capture detailed 3D data of the workpiece with high precision and low noise by coordinating a self-stabilizing three-axis gimbal centered around the STM32 microcontroller. We intend to use solidworks to build the three axis parts of the gimbal respectively, and print them out with a high-precision 3D printer, and then use the brushless motor to connect these parts, and control them with the STM32 code, so that it can achieve real-time angular correction, so that in the process of scanning can be done to achieve the lens anti-shake, reduce motion blur. ## 3D Reconstruction Subsystem This subsystem aims to obtain a point cloud through RGBD images and perform 3D reconstruction using the point cloud. We first use a depth camera to capture RGBD images of an object from different angles and preprocess the raw images by denoising and repairing. Then, we proceed with point cloud acquisition, registration, and reconstruction to obtain a 3D model. To begin, we calibrate the camera to obtain the lens parameters. We then convert the 2D coordinate system of the depth image to a 3D point cloud and map the pixel colors from the RGB image to the 3D point cloud. Afterward, we process the obtained point cloud by applying denoising and sampling techniques, facilitating subsequent registration and reconstruction steps. By repeating these processes, we obtain point clouds from different angles, and we perform precise registration using the ICP （Iterative Closest Point） method to align them in a unified coordinate system. Finally, the 3D reconstruction is completed using the Poisson reconstruction algorithm or other techniques. ## Database Subsystem This subsystem aims to store the basic information of the artifacts, including dynasties, historical backgrounds, stories, etc., and at the same time saving the generated complex 3D model data. With database system, users can upload the information of artifacts from all over the world to the database, and can also retrive and view the artifacts from exotic countries. When a user wants to retrieve an artifact, the database will find the corresponding information from its own stored data according to the search item entered by the user and display it through the Interactive Interface Subsystem for users to view artifacts from around the globe. ## Interactive Interface Subsystem This subsystem aims to provide a user-friendly interface that facilitates database interaction and basic visualization capabilities, delivering a visually pleasing experience to users and catering to their close-range viewing needs. We aim to present brief introductions of multiple cultural artifacts on the interface, including physical photos, names, dynasties, and more. Upon selection, users can access the corresponding detailed information and the reconstructed 3D model by linking to the database. Specifically, we render the obtained 3D models and offer features such as rotation and scaling for users to observe the artifact's details. Additionally, the interface can include a filtering function to provide users with a certain degree of personalized service in selecting artifacts. # Criterion for Success Successfully captures information about the appearance of artifacts without requiring the user to manually adjust examples or angles to minimize the noise. Accurate and detailed 3D scanning and reconstruction of artifacts. A database subsystem for effective data management and data retrieval. A user-friendly interactive interface provides an immersive experience in cultural heritage exploration. # Divisions Of Labor And Responsibilities Denglin Cheng is responsible for the modeling of the Stabilized Scanning Subsystem, 3D printing, and the design of the control circuits in the STM32, as well as the final assembly and debugging of the gimbal to ensure smooth scanning of the depth camera.

| # Smart Laundry FoldBot RFA ## Team Member Jiadong Hong EE Qianqi Liu ME Jialin Shang CompE Weijie Liang CompE ## Problem Laundry folding, a seemingly mundane task, can be surprisingly time-consuming, tedious, and even physically demanding. This project aims to enhance our overall well-being and quality of life by addressing the challenges associated with this commonplace but often underestimated activity. By alleviating the burden of laundry folding, the system we propose aims to liberate individuals to focus on more meaningful pursuits, contributing to a more harmonious and productive home environment. The primary challenge lies in developing a sophisticated machine capable of efficiently automating the clothing recognition and folding process. The system should integrate advanced computer vision capabilities to accurately identify and categorize different types of clothing items, such as shirts, pants, dresses, and more. Moreover, it must be adaptable to varying sizes and clothing styles, ensuring the folding process accommodates the diverse range of garments found in typical households. ## Solution Overview Our system automates laundry folding through: **Core Boards:** Four motorized boards fold clothing sequentially—Left, Right, Lower, and Upper—for precision. The Upper Board aids in easy clothing removal. **Expansion Plates:** Three adjustable plates adapt to clothing sizes, ensuring comprehensive folding for different dimensions. **CV Assistance:** We would use advanced computer vision for accurate clothing recognition and spatial understanding. **Kinetic Control System:** We would employ Reinforcement Learning for optimal folding and Exception-handling Algorithms for real-time adaptation. Our Automated Clothing Recognition and Folding System integrates these components, providing an efficient and user-friendly solution for a more harmonious and productive home environment. ## Solution Components ### Core Boards This component is essentially the primary folding mechanism, consisting of four specialized boards, each powered by an electric motor. These boards are designed to fold 180 degrees, enabling the sequential folding of clothing placed on them. The four boards are: #### a. Left Core Board: \- Positioned on the left side. \- Folds 180 degrees to the right. \- This action folds the left portion of the clothing (e.g., the left side of a shirt). #### b. Right Core Board: \- Located on the right side. \- Folds 180 degrees to the left. \- This mirrors the left core board's action, folding the right portion of the clothing. #### c. Center Lower Core Board: \- Situated below the central part of the clothing. \- Folds upwards 180 degrees. \- This folding step works on the lower part of the clothing, bringing it upwards and typically folding the garment in half. #### d. Center Upper Core Board: \- Located above the central part of the clothing. \- Also folds upwards 180 degrees. \- Completes the folding process by folding the upper portion of the garment. At this stage, the clothes are fully folded. \- This board may interact with an external system, such as a conveyor belt, to move the folded clothing away from the machine. ### Expansion Plates This component provides the system with the flexibility to handle various sizes and types of clothing. It comprises three adjustable plates: #### a. Left Expansion Plate: \- Adjacent to the left core board. \- Capable of extending or retracting to accommodate different clothing sizes. \- Specifically, it adjusts for clothing parts that extend beyond the left core board, like long sleeves, folding them appropriately. #### b. Right Expansion Plate: \- Positioned next to the right core board. \- Functions similarly to the left expansion plate but on the right side. \- Adjusts for the parts of the clothing that exceed the right core board. #### c. Lower Expansion Plate: \- Located below the central lower core board. \- Operates under the same principle as the other expansion plates. \- Adjusts for clothing parts that extend beyond the central lower core board, ensuring a complete and neat fold. ### CV Assistance #### **Object Detection:** Utilize sophisticated object detection algorithms, notably YOLO (You Only Look Once) or Faster R-CNN, to discern the spatial coordinates and categorical attributes of clothing articles. This facilitates a nuanced understanding of the depicted garments. #### **Image Segmentation:** Apply cutting-edge image segmentation methodologies, exemplified by Mask R-CNN or SAM, to differentiate various clothing items. This process effectively isolates clothing articles from the background, providing clear delineations that contribute to a detailed understanding of their spatial relationships and visual attributes. ### Kinetic Control System #### **Optimization Algorithms:** Reinforcement Learning: Adopt methodologies rooted in reinforcement learning paradigms, including Deep Reinforcement Learning (DRL), to facilitate the acquisition of optimal folding strategies through iterative learning mechanisms. #### **Exception Handling Algorithms:** Model Predictive Control (MPC): Implement MPC strategies for real-time adaptation of robotic arm dynamics, ensuring the accommodation of anomalous scenarios during the unfolding intricacies of clothing folding. Sliding Mode Control: Harness the robust attributes of sliding mode control mechanisms to mitigate uncertainties and adapt to dynamic variations encountered during the operational course. ## Criterion for Success The success of the Automated Clothing Recognition and Folding System will be measured based on the achievement of the following key criteria: **Precision in Folding:** The system must consistently fold various types of clothing items with a high degree of precision, resulting in neatly organized garments. **Integration of CV and Kinetic Control:** The successful integration of computer vision techniques for accurate clothing recognition (CV Assistance) and kinetic control algorithms (Kinetic Control System) to achieve optimal folding strategies. **User-Friendly Interface:** The interface must be intuitive and user-friendly, allowing users to interact easily with the system and monitor the folding process. **Safety:** Implementation of safety features is crucial to prevent accidents or damage to clothing items, ensuring a secure and risk-free operation. |

| # Problem When it comes to the disaster like avalanche bulletin and forest fires, we should investigate the landform with a specific technique. Also, this technique can deal with the snow profiling, ski track characterization or snow runaway characterization in snow. Understanding the structural integrity of soil and snow is vital for environmental management, agricultural practices, and civil engineering projects. Soil structure analysis informs us about the risk of erosion, the soil's ability to support plant life, and the stability of structures built upon it. Our project aims to fill the gap in on-site, accurate analysis of these structures and specifically designed for operation at low temperatures. By developing a portable and precise micro-penetrometer, we enable immediate, data-driven decision-making that can enhance safety, productivity, and environmental stewardship. # Solution Overview The main challenge of our project is to design an automated electronic control system capable of continuously drilling into different terrains, such as soil and snow, and using highly sensitive sensors at each location to record the penetration force and analyze the microstructural properties. The instrument must maintain a constant velocity during penetration, which requires a precise control mechanism. In addition, we need to design a mechanical system that is portable and field deployable to ensure operation in potentially harsh environmental conditions. We also need a software system to record real-time sensor data for subsequent analysis. Achieving such a high level of performance in a small, energy-efficient package that can withstand the rigors of varying ground conditions is a complex engineering task. It requires innovative approaches and collaborative efforts in mechanical, electrical and computer engineering to overcome these technical challenges. # Solution Components ## Control subsystem - piezo-electric force sensor with high accuracy to measure the penetration force at each location - the encoder of the motor ensures high accuracy in the vertical position - implement a feedback mechanism to adjust the drilling speed based on the resistance encountered. This will ensure optimal penetration regardless of varying soil or snow densities. ## Mechanical subsystem - the encoder of the motor ensures high accuracy in the vertical position - small brush can remove the snow from the gear teeth to avoid jamming of the motor and the rod - ski pols can be added to the measure unit to make the position stable - Li-Polymer battery to ensure the power of entire day - Aluminium profile to make the weight as light as possible so that it can be portable ## Software subsystem - Real-time data processing: To handle sensor input and control commands efficiently. - Data analysis algorithms: For interpreting penetration resistance and other measurements. - User interface: To display data and controls in an easily understandable format. - Data storage and export: For recording and sharing the collected data. - Potential integration of machine learning: For advanced pattern recognition in soil or snow structures. # Criterion for success There are three main criteria for the success of our project. The first is whether the device is portable. Compared to other similar products on the market today, we think that it’s successful if our device can be carried by one person on their back or by hand. The second criterion is to be able to ensure that the drill bit moves smoothly at a uniform speed through more precise electromechanical control. The final criterion is to have an algorithm that can read the snow or soil data within a reasonable margin of error. |

| # RFA ## Team Member - Yueshen Li, yueshen7 - Jianli Jin, jianlij2 - Di Wu, diw10 - Zihao Zhu, zihao9 ## Title Epicast: Augmented Board Game ## Problem Dungeons & Dragons (D&D) is a game that thrives on the breadth of imagination and the depth of interaction. It empowers players to construct elaborate worlds and characters that stem from the vast expanse of their creativity. This unfettered freedom not only offers a canvas for creation and interaction but also makes each gameplay experience profoundly personal and distinct. However, the richness of these imagined scenes and environments is often bottlenecked by the need for verbal expression and lacks an intuitive, sensory display. This limitation hampers the visualization of the game's full potential, presenting a hurdle for some players and constricting the game's broader allure. In addition, the Dungeon Master (DM) which is one of the players serving as the game's narrative architect, is often burdened with extensive preparatory work, juggling game mechanics with storytelling, which can be arduous and time-consuming. ## Solution Overview "Project Epicast" is a comprehensive system designed to enhance the Dungeons & Dragons gaming experience. Central to this system is a GPT-powered AI that serves as an automated Dungeon Master, guiding gameplay with intelligent narrative creation and player interaction. The visual aspect is handled by an overhead projector, capable of displaying intricate game scenes, animations, and simulating actions such as dice rolls directly onto the gaming surface. Its height is adjustable for optimal image quality. Gesture recognition is enabled through a sophisticated camera, allowing for intuitive control and the ability to capture memorable moments. Audio immersion is provided by integrated speakers and microphones for voice commands, narrative flow, and dynamic sound effects. Completing the sensory experience are ambient lights that adjust to the game's mood, providing synchronized lighting effects. Lastly, while our focus is on enhancing the D&D experience, it's important to recognize that our board game experience-augmenting module has widespread applications. The demand for immersive, enriched board game interactions extends beyond D&D. Our target example of D&D serves as an ideal prototype for a broader market of board games seeking similar enhancements for a more engaging player experience. ## Solution Components ### [Real-time Data Processing System] Real-time data processing system is used to capture, process and generate data in Real time. It consists of a data transmission module, a sophisticated camera, a projector, an integrated speaker and microphone, and an ambient light set. - Data transmission module is responsible for transmitting the data obtained from sensors to the processing unit of the system. And it should be responsible for transmitting the next instructions of sensors from processing unit and some data that sensors need to express. This can be done through a wired or wireless connection. - Camera is the core component of the real-time data processing system, used to capture image or video data. Those data will contain vital information like people’s hand gestures. The camera can be an ordinary USB camera, or it can be a high-resolution, high-speed industrial-grade camera. - Projector is another core component of the real-time data processing system. Projection is a technique for projecting an image or video onto an object or plane. In our setting, the projector needs to project images on a wall or slab to inform players of the game status. And the processing unit should send those related data to projector in real time. Same as Camera, the projector can be an ordinary USB camera, or it can be a high-resolution, high-speed industrial-grade camera. - Microphone will gather the voice of people and transform them into digital audio, and speaker will transform the digital data sent by processing unit to real voice. An intergrated speaker and microphone will deal with voice input and output of our whole model. - Ambient light set is used to provide ambient light source, provide sufficient lighting conditions that can adjust to the game's mood. So that the light set will provide synchronized lighting effects to enhance the player’s experience. Also, the light set may help to improve the visibility and recognition ability of the image according to the camera feedback and improve the recognition accuracy and accuracy of the real-time recognition system. ### [GPT-Core DM System] GPT-Core DM system acts as an assistant to Dungeon Masters (DM), providing support and assistance during gameplay. Through modeling and data training, GPT-Core as Dungeon Masters assistant should perform the following some basic functions and complete the game: - **Generate adventure missions and plot**: The DM can provide some key information to GPT-Core, such as mission type, location, character, etc., and GPT-Core can then generate a complete adventure mission with a reasonable game plot including enemies, puzzles, rewards, etc. - **Generate player’s character and NPC (Non-Player Character)**: The DM can use GPT-Core to ask players’ requirement of their willing characters, and then generate out their corresponding characters with balanced properties such as their backstory, personality traits, goals, etc. Also, GPT-Core can generate and provide detailed information of many NPCs easily to enhance game quality. - **Generate other detailed information**: DM can use GPT-Core to generate any detailed information, for an environment such as the layout of the room, decoration, smell, etc. And GPT-Core can generate vivid descriptions of the environment, allowing the player to better engage with the game world. Also, for interaction of player’s character and NPCs, GPT-Core may help to provide detailed descriptions of NPCs’ reactions according to player’s operations. That will make user immerse into game better. ### [Sensor Assistance System] Most of the time, we need to adjust projector orientation to let it project the screen to place we want or the camara’s orientation to make players’ hand gesture be captured. Design in mechanical engineering involves the physical structure and installation of the projector and the camera. Here are some common design considerations: - **Mounting bracket**: To securely mount the projector and camera in the desired position, a suitable bracket or mounting bracket needs to be designed. These brackets should be able to adapt to different mounting environments and provide adjustable features to fine-tune projection angles and positions. - **Adjustment mechanism**: To facilitate adjustment and alignment of the projector and camera, adjustable mechanisms such as rotation and tilt mechanisms can be designed to adjust under different projection angles and positions. - **Cooling system**: Projector and camera, especially projector, will generate heat during operation, so an effective cooling system may be necessary to be designed to ensure the stable operation of the projector and prevent overheating. - **Dust and protection**: To protect the projector and camera from dust, moisture and other external factors, it is necessary to design appropriate dust and protection measures, such as filters, seals, etc. - Other possible small mechanisms can be provided further to assist the rest sensors... ## Criterion for Success - Hand gesture and audio detections based on AI model are applied to depict players’ action. - Split game sense projector region and gesture detect region which are supposed to be a multi-module integrated hardware system ought to improve game experience. - Create a Dungeon Master AI using GPT as a core. - Create a better experience with a free-moving projector and several ambient lights. ## Distribution of Work - Yueshen Li will work on identification module and real-time signal transition system - Jianli Jin will work on GPT-DM model building and data training - Di Wu will work on hardware appliance construction and data logging system - Zihao Zhu will work on realistic design and extension module combination. |

| ## PROJECT DESCRIPTION Many real-world systems involve flows over networks. Our team aims to build a **modular, reconfigurable hardware emulator** to visualize network flows under capacity constraints on links. Each node can be configured to act as a sink, a source, or a "transfer station" that holds zero flux. This toolset will facilitate the understanding of flow optimization algorithms in a classroom setting. ## SOLUTION OVERVIEW We use a scalable design where components are easily replaceable to account for network expansion. The emulator should have a central Arduino controller that talks to each node and link to display the capacities and actual flow amounts. *Tentative: It may be desirable to have a software GUI to display the network alongside the physical model due to space (# LEDs) and protocol (# pins) constraints in each node/link.* ## SOLUTION COMPONENTS ### Subsystem 1: Physical Network Model - We should build a fully functional physical model where pipes represent network links and the LEDs within show the maximal capacity and real-time flow of "data packets." - Each node should be configurable as sink, source, or neither ("transfer station") with a user-friendly interface such as buttons or switches. ### Subsystem 2: Software Flow Computer - We should build an intuitive software interface that allows the user to easily configure nodes (3 modes) and links (capacity) while controlling the LED flow display. - We should implement a robust and *lightweight* optimization algorithm that efficiently computes network flows on an embedded Arduino board while considering all constraints (node configurations, link capacities). - Alongside the design process, we should write comprehensive documentation detailing the manuals for software setup, operation, troubleshooting, and our development process. ## CRITERION OF SUCCESS - The physical model should be modular, i.e., each node has a certain number of "slots" reserved for installing new links (pipes). - The Arduino software should communicate with all nodes and pipes and update the flows in real-time in response to changes in setup. At the current stage, we aim to serve 4~6 fully connected nodes. - The algorithm should handle (and report) edge cases such as a network with zero or multiple feasible flows. ## DISTRIBUTION OF WORK - Ziyuan Chen (ECE) - software developer: maintain the code for flow optimization and Arduino-hardware communication protocol - Bolin, Jiahao (EE) - hardware developer: handle the physical layout of peripherals (pipes and LEDs), design user interface - Yiyang Huang (ME) - integration and testing specialist: design the protocol for node configuration and conduct stress tests in edge cases |

| ## Problem Statement Traditional wind energy systems often face challenges related to suboptimal power extraction, limited adaptability, and inadequate integration with smart grids. Conventional wind power systems usually requires a giant turbine which produces power for the grid. Yet a new trend arises in recent years where a small wind power system is installed on a fisher or on the roof of a villa. Such scenario requires a stable power converter and router to ensure stable power supply, which not only allows the user to use cheap and clean wind energy, but is also able to switch to battery or mains when wind force is too light to drive the turbine or when the turbine is in fault. ## Solution Overview and Components The proposed solution involves the development and implementation of the system integrated with a MPPT-based wind turbine. This comprehensive solution aims to address the inefficiencies and limitations of traditional wind energy systems by incorporating advanced technologies for optimal power extraction, intelligent management, and seamless integration with smart grids. Some key components of the solution are as follows: 1. **Wind turbines.** The project plans to use a three-phase asynchronous motor to build a down-scaled wind turbine. The turbine should produce no more than 30 V AC output under normal weather condition with wind speed less than 8 m/s (force 4). (Similar turbine with suitable size (diameter = 1.1 m) for the project appears on Taobao, which has rated output voltage 12 V, maximum power ranges from several hundred watts to kilowatts, and can work safely within wind speed 35 m/s (wind force 6). Link to the turbine) 2. **MMC-Based AC-DC converter.** This unit is expected to provide stable DC output for users. Its controller consists of MCUs and voltage sensors. The converter should be designed using MMC technology and should be able to implement Maximum Power Point Tracking (MPPT). 3. **User interface.** This unit displays real-time current, voltage and power of the system. 4. **Simulated mains.** This is a low-voltage (<30 V) power supply that simulates the mains. It is apparently down-scaled for safety considerations. 5. **Routing system.** This unit should be able to decide which power should be connected to the load, the turbine or the simulated mains. 6. **Safety.** An emergency stop button should be connected to the circuit in order to cut off all power sources and stop the turbine whenever an emergency happens. Control units should be able to cut the power when the system is overload or in fault status. The solution should fit in relevant national or industrial standards. ## Criterion for Success The design will be tested using various common loads that is used at home. The following criterion should be satisfied to indicate a successful design: 1. **Safety is the first priority**. All safety measures should be working properly. 2. The controller should be able to keep the converter working at the maximum power point. 3. The MMC converter should be able to provide stable output with current and voltage ripple less than $\pm10\%$. 4. The controller should switch between power supplies within a short period of time (specific time limit needs to be determined after further research on relevant national standards and other technical documents). ## Distribution of Work The project can be divided into three modules – the power system, the control system, and the mechanical system. - The power system deals with everything related to power transmission, include the design of generators and converters. - The control system provides control signals to the converter, properly routes power to the load, and provide safety measures. - The mechanical design should put every hardware components organized to form a ready-to-use product, and print necessary instructions and warnings at proper places. The following is the detailed task division: - Power system and circuit design: Rong Li & Zhekai Zheng - Control system and circuit design: Tiantian Zhong & Rong Li - Mechanical design and manufacturing: Zhekai Zheng - Purchasing, finance, and other miscellaneous affairs: Tiantian Zhong |

Knowing where you are, how to get to your destination, how to optimize your routes, knowing factors that will influence your routes can be complicated. Having a real-time interactive system that guides people through this process is needed. It has been possible yet not able to scale because it’s not open-sourced, and its hardware isn’t standardized, and is expensive. The interaction isn’t versatile enough to adapt well under the ever-changing applications. A cheap and versatile solution is needed. ------ # 💭 Proposal ## Solution Overview Our solution utilizes autonomous UAV to guide our clients, sensing them and the environment, such as obstacles and drone’s location with a sensor module, controlled by a control unit which orchestrate a series of tasks.

| # Team Members Chengrui Wu (cw70) Hanggang Zhu (hz66) Haoran Yuan (haorany7) Lizhuang Zheng (lzheng17) # Project Title Fingerprint Recognition Door Lock # Problem In our Residential College dormitories, each room door requires a student IC card to unlock. However, sometimes students may forget to bring their own card with them when they are out. The current solution is to apply for a temporary card, so a fingerprint recognition door lock can be a better solution. Currently, most fingerprint recognition door locks are integrated units. To install a new one, users must remove the entire old lock, typically requiring professional assistance. But updating all the locks in the Residential College is a huge project, and may affect students’ daily life. Thus, we propose a more user-friendly solution that allows users to integrate advanced fingerprint recognition technology with their current locks, without the needs of extensive installation processes, so that students can install the device by themselves. # Solution Overview We aim to create a smart, compact device that can be added to existing locks, enabling fingerprint-based unlocking. So that students can install the device easily by themselves. This device will feature a fingerprint recognition module, a control unit, mechanisms for lock interaction, a mobile app for management and GPS integration, and a wireless communication module. Besides, a security module and a power supply module are needed to support other subsystems. # Solution Components ## Capacitive Fingerprint Sensor Module This module will feature a state-of-the-art capacitive fingerprint sensor, known for its high sensitivity and accuracy in capturing detailed fingerprint images. It is designed to efficiently transmit high-resolution fingerprint image data to the Fingerprint Recognition Subsystem. The sensor's advanced technology allows it to quickly and accurately read a fingerprint, even under varying environmental conditions. Its compact size and low power consumption make it an ideal choice for integration into the smart door lock system. The sensor will be interfaced with the STM32 development board, ensuring seamless communication and data transfer between the sensor and the Fingerprint Recognition Subsystem. ## Fingerprint Recognition Subsystem This will be a high-precision module with algorithms capable of accurately identifying the user's unique fingerprint patterns. It will also be able to store multiple fingerprints the user registered, for shared use among the user and other authorized individuals. The code implementation will be written into STM32 develop board to output True/False signal to the downstream controller subsystem. ## Controller Subsystem This will be a microcontroller that manages the operations of the device, including processing fingerprint data, controlling lock mechanisms, and coordinating with the mobile app and a wireless communication module designed to retrieve messages from the app. We may choose a STM32 develop board with Wi-Fi module as the platform. ## Software UI A mobile app for fingerprint recording and remote lock control. It will allow users to manage their fingerprints, remotely control the lock, and adjust settings such as auto-lock and unlock. It will also provide notifications about lock status and usage. ## Wireless Communication Module An ESP8266 microchip for Wi-Fi connectivity with secure protocols, and a GPS module for location tracking. The microchip will provide the device with Wi-Fi connectivity to communicate with the mobile app, receive updates, and enable remote access and control. The module will also use secure protocols to ensure data privacy and security. Based on the GPS location of the users’ mobile phone, it will allow the lock to unlock automatically when the user's phone is nearby, and lock automatically when it is too far away, ## Security Module The security module ensures secure wireless communications and app usage, prevents unauthorized access, and verifies user identity. It uses advanced encryption for data transmission and includes mechanisms for detecting and reporting security breaches. ## Mechanical Engine An actuator to engage/disengage the existing lock mechanism. These will be designed to be compatible with the dorm lock design and will physically engage and disengage the lock mechanism in response to input from the control unit. ## Power Supply Subsystem This system will include a battery and other components used to power up all the subsystems above, it should be able to last for a significant period. # Criterion for Success - Efficient and accurate fingerprint-based unlocking. - Remote access and control of the lock's status through the app, ensuring exclusive user access. - Ease of installation and removal from the existing lock, with robust security. - Lock the door from inside, when the person is left # Distribution of Work - Chengrui Wu: Microcontroller and Software App - Hanggang Zhu: Software App, Fingerprint Recognition and Security Module - Haoran Yuan: Wireless Communication and Fingerprint Recognition, Chip and sensor selection. - Lizhuang Zheng: Mechanical Engine, Microcontroller and Power Supply Subsystem |

| # TEAM MEMBERS Zhenyu Zhang (zhenyuz5) Benlu Wang (benluw2) Luozhen Wang (luozhen2) Suhao Wang (suhao2) # PROBLEM I-clicker is an educational tool employed by ZJUI to fulfill the digital demands of the classroom, serving as a class check-in and answer device. However, the existing transmitters and receivers face limitations in terms of their capacity to handle substantial loads, high signal delay, and signal loss. These constraints hinder the device's ability to effectively meet the requirements of a large number of users. Additionally, the current I-clicker system fails to cater to the preferences of students who prefer to utilize mobile applications for participation. # SOLUTION OVERVIEW This project aims to design and develop a comprehensive classroom response system that supports multiple frontends, including web browsers, mobile applications (iOS and Android platforms), WeChat Mini Programs, and physical Clickers. Additionally, a user-friendly web-based interface will be created to provide teachers with intuitive management functionalities. The system incorporates a high-concurrency unified backend equipped with distributed and in-memory databases, offering caching capabilities to efficiently handle large volumes of student submissions, as well as perform evaluation and statistical analysis. The project also entails the shell design and implementation of a distributed and energy-efficient transmission system for the physical Clickers and their receivers to address the limitation of signal loss. # SOLUTION COMPONENTS This project encompasses four essential components: frontend development, backend optimization, hardware improvement, and enclosure design. ## Frontend Development: For instance, we can develop a user-friendly web-based interface using popular frontend technologies such as HTML, CSS, and JavaScript. This interface can be accessible through standard web browsers on various devices, offering teachers the flexibility to manage the voting result. Additionally, as part of the meticulous frontend development process, the project aims to provide students with diverse options to interact with the voting system. As we possess a physical clicker as part of our system, our commitment lies in ensuring compatibility and functionality between the mobile app and the physical clicker, allowing both to transmit signals that can be effectively processed by the receiver. Furthermore, if time permits, the project can also develop WeChat Mini Programs. These lightweight applications within the WeChat ecosystem provide a seamless and familiar voting experience for students who prefer to use the WeChat platform. ## Backend Development: By constructing a high-concurrency unified backend, fortified with distributed and in-memory databases, the system will be empowered with caching capabilities capable of effectively managing the influx of student submissions. In this scenario, the system can employ a distributed database system, such as Apache Cassandra or Amazon DynamoDB, to handle the storage and retrieval of student submissions. By distributing the data across multiple nodes, the system can benefit from increased scalability and fault tolerance. To further enhance performance, an in-memory database, such as Redis or Apache Ignite, can be utilized as a caching layer. This allows frequently accessed data, such as student responses and evaluation results, to be stored in memory for faster retrieval, reducing the need to repeatedly access the distributed database. ## Hardware Improvement: Recognizing the significance of enhancing reception capabilities, the project dedicates attention to the development of a distributed and energy-efficient transmission system for the physical Clickers and their corresponding receivers. The voting system incorporates a System-on-Chip (SoC) solution to handle both the transmitter and receiver functionalities. The SoC, such as ESP32 or STM32, integrates microcontroller capabilities and offers built-in wireless connectivity options like Wi-Fi or Bluetooth. The SoC transmitter facilitates the transmission of votes from the voting devices to the central system using its dedicated peripherals for user input. The SoC receiver receives the transmitted votes, establishes a reliable connection with the voting devices through Wi-Fi or Bluetooth, decodes the received data, and manages the voting information effectively. This integrated approach utilizing SoC technology ensures seamless bidirectional communication, efficient data transmission, and reliable vote collection within the voting system. ## Enclosure Design: In addition to the technical facets, the project encompasses the meticulous design of an enclosure, using 3D printing technology, specifically tailored for the physical Clickers. This component embraces the principles of aesthetics, functionality, durability, ergonomics, and user-friendliness. By prioritizing these design considerations, the enclosure aims to enhance the overall user experience, ensuring that the physical Clickers are comfortable to handle and operate. # CRITERION FOR SUCCESS Concurrency Handling: Build a high-concurrency backend system for efficient processing of large volumes of student submissions concurrently. Affordability: Develop cost-effective i-clickers to promote widespread adoption and accessibility for students. Support for Multiple Frontends: The system should be designed to support multiple frontends, including mobile applications, web browsers, and dedicated software, ensuring compatibility, seamless interaction, and consistent user experience across various platforms. Signal Stability: Ensure reliable signal reception in challenging environments and minimize signal loss within classrooms. Distributed and Energy-Efficient Transmission: Implement a distributed transmission system with low-power consumption to optimize device performance and energy efficiency. Aesthetic Design: Create visually appealing i-clicker shell designs that are widely accepted and facilitate customization through 3D printing. # DISTRIBUTION OF WORK Benlu Wang: Responsible for designing and developing web-based interfaces, mobile applications, and WeChat Mini Programs to provide a range of frontend options for students to interact with the voting system. Zhenyu Zhang: Tasked with optimizing the backend infrastructure, including the development of a high-concurrency unified backend, distributed and in-memory databases, and efficient data management for seamless operations.

In addition, features such as AI prediction and intelligent control may be added to optimize the power consumption of the Haining campus. # Solution Our project plan is to build a physical model of the power system in the Haining International Campus of Zhejiang University and to perform power flow calculations using electricity consumption data from the Engineering Department. The brightness/different colors of LED strips are used to represent the current, voltage, power and other information. Based on this, anomaly detection can be implemented for various types of behaviors within the grid, such as abnormal user behaviors and grid infrastructure failures. Given the historical data of power consumption, we can build a vivid demonstration of the power flow inside the campus across the year. Based on that, we can also make predictions of how the power usage will change in the future. If given the live data of power consumption, we will be able to integrate them into our system, both for live demonstration and power monitoring. We also plan to use event-driven algorithms to autonomously detect abnormal conditions or disturbances. Other advanced applications, such as AI intelligent control, grid loss calculation, and installation and connection of distributed wind/photovoltaics power sources can also be developed. # Solution Components (and Distribution of Work) 1. Physical model of the campus -- Solid modeling of international campus districts using 3D printing technology or other modeling methods(Yilang Feng) 2. Power Flow Calculations -- Use software such as OpenDSS or Matpower to calculate the power flow of the electricity consumption of the campus(Tiantong Qiao), and control the LED light bar to display horizontally.(Erkai Yu) 3. Advanced Applications: -- Power usage anomaly detection, AI intelligent control, event-driven short circuit analysis, grid loss calculation, distributed photovoltaic generation, etc(Jiahe Li). # Criterion for Success The success of our project hinges on achieving key performance criteria, including the precision and accuracy of our power flow modeling. Utilizing software like OpenDSS or Matpower, we aim to attain a high level of accuracy in depicting the power flow within the campus, ensuring close alignment with historical and real-time power consumption data. In parallel, the construction of a physically accurate model of the international campus, employing 3D printing technology or other methods, is crucial for creating an immersive and realistic demonstration. Additionally, the implementation of LED strips with varying colors and brightness levels, responsive to calculated power flow and real-time data, is essential for effective representation. Furthermore, the success criteria encompass the accurate prediction of future power usage based on historical data, validation against real-time data, seamless integration of live power consumption data, and the autonomous detection of abnormal conditions through event-driven algorithms. The project's success is further evaluated through the successful implementation and practical assessment of advanced applications such as AI intelligent control, grid loss calculation, and the integration of distributed wind/photovoltaic power sources to enhance the overall capabilities of the campus power system. |

Capable of identifying and navigating in indoor spaces, which have varying lighting situations including bright natural sunlight to dim artificial lights, and obstacles such as furniture and shelves. 2. The voice response system should also be easy to use, so it must respond timely and interact in natural language with the user (Users don’t need to learn the extra commands). The voice response system should also be easy to use, so it must respond timely and interact in natural language with the user. 3. When search request received from PC, our microcontroller of STM32F103c8t6 should send the correct impulse signal to control the 360° steering engine to automatically stop when the desired object is detected by the camera attached to it. The difference of the direction of the camera to the actual direction of the desired object should be within 3°. 4.

| ## Team Members Li Mingchen (ml110), Zheng Jiakai (jiakaiz4), Wang Shenao (shenaow2), Luo Xiao (xiaoluo5) ## Project Title **Robotic T-shirt Launcher Mark III** ## Problem 1.The previous version of MARK II is excessively bulky for convenient portability and usage. It is imperative to reduce the dimensions and weight of the T-shirt launcher. 2.The shirt launcher is equipped with insufficient spare ammunition. It is necessary to ensure a minimum of three shots or enhance its firing rate. 3.To address system uncertainties, a comprehensive risk assessment should be conducted during the design phase to identify potential sources of uncertainty and their potential impacts. Mitigation strategies, such as redundant safety mechanisms, backup systems, and robust testing procedures, can be incorporated to minimize the effects of uncertainty on the system's performance and reliability. ## Solution Overview While preserving the achievements of ROBOTIC's T-SHIRT LAUNCHER MARK II, our team will address critical flaws. For example, the MARK II was too large and heavy for its function, and the MARK II fired too slowly. In addition, in terms of automation of the system, we will also try to achieve the unfinished goals of the MARK II and ensure safety by optimizing the launch trajectory. ## Solution Components Launcher system: The launcher system consists of an air chamber made up of gas cylinders, gas cylinders used to inflate the air chamber, an inlet valve, an exhaust valve, an exhaust trigger, and a barometer (for detecting the air pressure in the air chamber). These components are used to rapidly inflate and launch the T shirt through differential air pressure. Two Degree of Freedom Targeting Gimbal: This targeting gimbal consists of a stepper motor, reduction gear sets and aluminum frame structures. It consists of two degrees of freedom of motion, which enables precise control of the pitch and horizontal rotation angles in a stable manner while achieving light weight. The purpose is to adjust the position of the launcher in 3D space after receiving electrical signals from the control system so that the T-Shirt can be successfully launched to the desired place. Control System: The Control System plays a crucial role in efficiently managing the components of the system. It encompasses a gimbal controller, actuator controllers, electromagnetic valves, and a microcontroller like Arduino. They work together to ensure smooth and accurate operations, control the release of compressed air and keep the pressure in safe operating limits. Automation System: For the case of use on the gimbal, we want the launcher to be able to fire automatically. Therefore, the system should have a suitable function to automatically adjust the direction and force of the launch according to the situation. In addition, for safety reasons, the system will include a computer vision module to conduct spectator behaviour recognition to avoid potential accidents, such as stampedes. ## Criterion for Success Functionality of Launcher: The launcher should be able to fire T-shirts. The force of the launch can be changed by controlling the air pressure inside the launcher at the time of launch. The system should be able to simplify the operation by pre-loading the T-shirt in a certain amount. The operator can easily operate the transmitter with the trigger. Firing Rate: The launcher should have a relatively fast firing rate, which is determined by three key factors: the rate at which the gas chamber inflates to reach the desired pressure, the rate at which the controller controls the closing and opening of the valves, and the rate at which the T-Shirt bullet is loaded. The desired pressure of the chamber will determine the force of the shot, which can be controlled by adjusting the valve closing time, and the chamber will be equipped with a barometer to allow the operator to accurately control the force of the shot and make adjustments. Smaller Size and Weight: Reducing size and weight was one of the main objectives of this MARK III design, and for this reason we abandoned the rotary round change design of the MARK II and adopted a loaded round change design to reduce redundant size. Secondly, the weight of the gas chamber will be reduced. Two large gas cylinders are used in the MARK II, and in fact, the small volume of a single cylinder provides gas that is perfectly adequate for firing at least 40 rounds of ammunition. Then there is the reduction of overall size and weight, which is achieved by simplifying the frame design of the transport vehicle, and the overall size of the launcher. Safety: Since the launcher uses a pressure vessel, security considerations are very important to the system. The key parts of the launcher must have components to detect safety metrics, such as barometric values. In addition, for accidents that may occur during use, we should take into account and design safety mechanisms. ## Distribution of Work Li Mingchen: Automation System Zheng Jiakai: Launcher system Wang Shenao: Targeting Gimbal System Luo Xiao: Control System |

| # Problem Today, both the primary and secondary industries need to carry out technology-led industrial upgrading, in such a process, how to efficiently detect the work flow is a major problem. For example, in the fields of agricultural inspection, power line and infrastructure inspection, environmental protection and wildlife monitoring, an effective, high-speed and wide-ranging inspection method will increase the productivity and accuracy of related industries. # Solution Overview The solution we give is to develop an eVTOL drone that can meet a certain load bearing, set up corresponding communication modules and cameras for it, and transmit real-time data back to the data cloud we build on the server, so as to achieve a large range and long distance accurate detection. # Solution Components ## Foam Board Body The foam plate body provides lower weight, thus reducing energy consumption and ensuring adequate performance in terms of movement and acceleration, while it has good insulation, which can effectively reduce heat transfer and noise diffusion. During the engineering phase, its characteristics made the air frame easy to process and had good impact protection characteristics. At the same time, foam board is also a more economical and environmentally friendly approach. ## Power System Internal micro controller for A/D conversion and initial signal processing ( Atmel atmega328 SIM Card Service ) Use SIM cards to provide identity authentication and data transmission in drone and cloud communications. SIM card technology allows drones to connect to a specific cellular network operator and use its network infrastructure to communicate remotely. In this way, the drone is not limited by distance, is able to perform long-distance missions, and can upload data to the cloud in real time. At the same time, it also ensures continuous connectivity between the drone and the cloud, and the drone can maintain a continuous network connection in the covered area. This allows for prolonged monitoring or data acquisition activities while enabling near real-time data analysis and decision support. ## Camera Cameras rely on built-in image sensors, such as CMOS or CCD, to convert light into electronic signals. These sensors divide the screen into pixel points, each point can record color and brightness information, analog cameras will capture the image into analog signal output; The digital camera further converts the analog signal to A digital signal through an A/D (analog-to-digital) converter. By reducing its size through encoding and compression algorithms (such as H.264, H.265) to reduce the bandwidth requirements during transmission, the compressed video data can be transmitted through the SIM's cellular network and stored in the cloud. # Criterion for Success Our aircraft must be able to lift more than 2kg and maintain smooth horizontal and vertical flight, while our cloud needs to be stable and receive video information from drones flying on the road |

| **Project Advisor:** Dr. Cristoforo Demartino **Team Members:** - Kowshik Arko Dey [arkod2] - Hanchi Ge [hanchig2] - Rongjian Chen [rc21] **Problem:** Bridges are one of the most vital infrastructures that serve as connectors both inside and outside of a country. They facilitate the movement of people, goods, and vehicles. Despite being marvels of engineering and architecture, accidents in bridges have become more frequent as time passes. The significant causes can be attributed to as being vehicle overloading and structural concerns of the bridge. These type of accidents are more prominent in third world countries, like Bangladesh, where most of the bridges have no monitoring system due to the cost involving these traditional monitoring systems. As a result, the drivers are left to their own assessments and judgements which may lead to accidents and structural damage to the bridges. The development of digital monitoring system can effectively save the money wasted on repetitive maintenance and repair of bridges due to overloading and structural damage. **Solution Overview:** The Digital Twin Bridge Monitoring System is designed to address the critical issue of bridge safety and maintenance. This innovative system involves the creation of a digital counterpart for a physical bridge, which is outfitted with advanced pressure sensors. These sensors are crucial for accurately gauging the weight of vehicles as they traverse the bridge, ensuring that the bridge's load capacity is not exceeded. Additionally, the system is equipped with a traffic light mechanism. This feature plays a vital role in warning drivers about potential overloading or existing structural issues, thereby enhancing safety measures. To demonstrate the practicality and functionality of this system, we plan to construct a scaled-down prototype model. This model will serve as a platform for installing our hardware components, which include various modules such as sensors and a micro-controller. The key to our system's effectiveness lies in the ability to transmit the sensor's processed data to the digital twin platform. This enables the real-time monitoring and detection of the bridge's condition, allowing for immediate responses to any detected problems. Through this advanced monitoring system, we aim to revolutionize how bridge safety is managed, ensuring the longevity and reliability of these critical infrastructures. **Solution Components:** *Pressure Sensor Subsystem Overview* The Sensor Subsystem is strategically designed for early detection of potential risks posed by overweight vehicles. Situated in every lane at the initial incline of the bridge, pressure sensors are meticulously installed. Their primary role is to identify vehicles exceeding the weight limit. Upon detection, the traffic light will show red. *Displacement Subsystem Overview* Displacement sensors are used to measure the displacement of a bridge structure, which is critical for us to assess the structural safety of a bridge. Displacement sensors will be strategically placed at key points in the bridge structure, such as supports, beams and joints, to ensure we can fully monitor the health of the bridge. *Processing Subsystem Details* The operation of the Processing Subsystem is pivotal for maintaining traffic flow and ensuring safety. Under standard operational circumstances, the traffic signal lights are set to green, allowing vehicles to pass. However, the system is on constant alert for overweight vehicles. The moment an overweight vehicle is identified, the traffic lights switch to flashing red, serving as a clear warning to drivers to halt and not to enter the bridge. Further, should there be any detected structural deformation within the bridge, the signal lights will steadfastly remain red. Moreover, to prevent any approach towards the potentially unsafe bridge, all traffic lights leading to it from the preceding intersection will be deactivated. The heart of this subsystem is an internal micro-controller responsible for Analog-to-Digital (A/D) conversion and the initial stages of signal processing. - **Signal Conditioning:** The raw signals from the sensors are often weak and noisy. Signal conditioning modules are used to amplify, filter, and convert these signals into a format suitable for digital processing. - **Analog-to-Digital Conversion (ADC):** The conditioned analog signals are converted into digital data through ADC. This conversion is essential for the subsequent data analysis and digital twin simulation. - **Data Processing Unit:** A micro-controller processes the digital data, performing preliminary calculations and data compression to reduce the amount of data to be transmitted. - **Data Transmission:** The processed data is transmitted to the Digital twin software. *Power Subsystem Functionality* It efficiently converts AC power, commonly available from standard outlet sources, into the DC voltages required by the various components of the system. This includes the sensors, micro-controller, and communications modules, thereby guaranteeing their uninterrupted operation and performance. **Criterion for Success:** Successful development and integration of the scaled physical model, software, and hardware components. The scale model can use pressure sensors to measure the weight of the passing model car, and when the weight of the car exceeds our preset standard, the signal light of the scale bridge will be red to warn the driver. At the same time, the signals obtained from the scale model, such as pressure signals and structural deformation signals of the bridge, need to be transmitted in real time to the digital twin monitoring system.
