**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.

# PROBLEM

Tea is a popular beverage but cannot be easily obtained like coffee because no machine on the market can make it as convenient to drink tea as a coffee machine. Additionally, people’s requirements for the type and strength of tea are just as complex as those for coffee. We want to design a device that allows users to input the type of tea they want to drink and their taste preferences and then receive a cup of tea that meets their requirements.”

# SOLUTION OVERVIEW

This machine has a total of five systems: an interactive subsystem that receives user input, a control subsystem that controls all other subsystems, a solid storage subsystem for storing tea leaves, a tea brewing subsystem that adds an appropriate amount of water at the right temperature, and a flavour subsystem for adding additional ingredients such as milk and sugar.

# SOLUTION COMPONENTS

##INTERACTIVE SUBSYSTEM

The interactive subsystem includes a series of digital displays and buttons for users to adjust parameters related to taste, such as tea strength, temperature, and concentration of additional ingredients. It is also capable of delivering this data to the control subsystem.

## CONTROL SUBSYSTEM

The control subsystem is capable of transmitting signals to other subsystems and can control the number of tea leaves and additional ingredients used, as well as the temperature and amount of water used, and the overall brewing time.

## TEA BREWING SUBSYSTEM

The tea brewing subsystem includes a mixing tank that can store the added tea leaves, water, and additional ingredients and can dispense the brewed tea and tea leaves together at the set time.

## FLAVOR SUBSYSTEM

The flavouring subsystem includes tanks for storing syrup and milk, as well as pipelines and valves for adding a predetermined amount of syrup and milk based on instructions from the control subsystem.

# CRITERION FOR SUCCESS

After users set their taste preferences on the front-end interface, they can wait for a certain amount of time and then enjoy a cup of tea that meets their preferences. After each tea-making process, the machine’s interior is relatively clean and there are no residual tea leaves that could affect the taste or food safety.

# DISTRIBUTION OF WORK

Zhiyuan Wang is responsible for designing the mechanical structure, including the outer shell, storage compartment, and liquid pipelines. Anyu Ying is responsible for designing and soldering the circuit board. Zhenzuo Si and Ruiqi Ye are responsible for developing and debugging the control and interaction systems.
