Final Presentation

Description

Presentations of the projects are given a few days after the Final Demo to an audience of fellow student reviewers, the lab instructors, and occasionally faculty or even students from outside the class who are following up a project of personal interest to them. The style is formal and professional, and students should dress accordingly (Generally business professional, or what you would wear to a career fair).

Requirements and Grading

Each project team has 25 minutes for a Powerpoint presentation and questions. Every group member must present their own work contributing to the project and be ready to answer questions. Presentations are judged on the basis of presentation technique and of technical organization and content.

Presentation technique includes dress, use of display materials (slides), clarity of speech, absence of filler words/fidgeting, proper eye contact with audience and smooth transitions between speakers. Content is judged on use of a proper introduction, orderly and connected development of ideas, absence of unnecessary details, proper pacing to stay within the allotted time, and an adequate summary at the close of the talk. Quantitative results are expected whenever applicable. Here is a general outline to follow:

  1. Introduction to your team and your project.
  2. Objective. What problem are you solving?
  3. Brief review of original design, statement on areas of design that changed, and overview of each functional block's requirements.
  4. Description of project build and functional test results. You can choose to include a short (30s) video of your project here.
  5. Discussion of successes and challenges, as well as explanations of any failed verifications demonstrating and understanding of the engineering reason behind the failure
  6. Conclusions from the project: what did you learn, what would you do differently if you redesigned your project, etc.
  7. Recommendations for further work.

Any significant, relevant ethical issues should be briefly addressed, preferably in a single slide.

Presentations will be graded using the presentation grading rubric. Your slides should follow ECE or College of Engineering presentation theming.

Submission and Deadlines

Slides for your final presentation must be uploaded to your project page on PACE prior to your presentation time. Deadlines for signing up may be found on the Calendar. Sign-up for the final presentation is done through PACE. Remember to sign up for a peer review of another group.

Featured Project

# Electronic Mouse (Cat Toy)

# Team Members:

- Yingyu Zhang (yzhan290)

- Chuangy Zhang (czhan30)

- Jack (John) Casey (jpcasey2)

# Problem Components:

Keeping up with the high energy drive of some cats can often be overwhelming for owners who often choose these pets because of their low maintenance compared to other animals. There is an increasing number of cats being used for service and emotional support animals, and with this, there is a need for an interactive cat toy with greater accessibility.

1. Get cats the enrichment they need

1. Get cats to chase the “mouse” around

1. Get cats fascinated by the “mouse”

1. Keep cats busy

1. Fulfill the need for cats’ hunting behaviors

1. Interactive fun between the cat and cat owner

1. Solve the shortcomings of electronic-remote-control-mouses that are out in the market

## Comparison with existing products

- Hexbug Mouse Robotic Cat Toy: Battery endurance is very low; For hard floors only

- GiGwi Interactive Cat Toy Mouse: Does not work on the carpet; Not sensitive to cat touch; Battery endurance is very low; Can't control remotely

# Solution

A remote-controlled cat toy is a solution that allows more cat owners to get interactive playtime with their pets. With our design, there will be no need to get low to the ground to adjust it often as it will go over most floor surfaces and in any direction with help from a strong motor and servos that won’t break from wall or cat impact. To prevent damage to household objects it will have IR sensors and accelerometers for use in self-driving modes. The toy will be run and powered by a Bluetooth microcontroller and a strong rechargeable battery to ensure playtime for hours.

## Subsystem 1 - Infrared(IR) Sensors & Accelerometer sensor

- IR sensors work with radar technology and they both emit and receive Infrared radiation. This kind of sensor has been used widely to detect nearby objects. We will use the IR sensors to detect if the mouse is surrounded by any obstacles.

- An accelerometer sensor measures the acceleration of any object in its rest frame. This kind of sensor has been used widely to capture the intensity of physical activities. We will use this sensor to detect if cats are playing with the mouse.

## Subsystem 2 - Microcontroller(ESP32)

- ESP32 is a dual-core microcontroller with integrated Wi-Fi and Bluetooth. This MCU has 520 KB of SRAM, 34 programmable GPIOs, 802.11 Wi-Fi, Bluetooth v4.2, and much more. This powerful microcontroller enables us to develop more powerful software and hardware and provides a lot of flexibility compared to ATMegaxxx.

Components(TBD):

- Product: [https://www.digikey.com/en/products/detail/espressif-systems/ESP32-WROOM-32/8544298](url)

- Datasheet: [http://esp32.net](url)

## Subsystem 3 - App

- We will develop an App that can remotely control the mouse.

1. Control the mouse to either move forward, backward, left, or right.

1. Turn on / off / flashing the LED eyes of the mouse

1. keep the cat owner informed about the battery level of the mouse

1. Change “modes”: (a). keep running randomly without stopping; (b). the cat activates the mouse; (c). runs in cycles(runs, stops, runs, stops…) intermittently (mouse hesitates to get cat’s curiosity up); (d). Turn OFF (completely)

## Subsystem 4 - Motors and Servo

- To enable maneuverability in all directions, we are planning to use 1 servo and 2 motors to drive the robotic mouse. The servo is used to control the direction of the mouse. Wheels will be directly mounted onto motors via hubs.

Components(TBD):

- Metal Gear Motors: [https://www.adafruit.com/product/3802](url)

- L9110H H-Bridge Motor Driver: [https://www.adafruit.com/product/4489](url)

## Subsystem 5 - Power Management

- We are planning to use a high capacity (5 Ah - 10 Ah), 3.7 volts lithium polymer battery to enable the long-last usage of the robotic mouse. Also, we are using the USB lithium polymer ion charging circuit to charge the battery.

Components(TBD):

- Lithium Polymer Ion Battery: [https://www.adafruit.com/product/5035](url)

- USB Lithium Polymer Ion Charger: [https://www.adafruit.com/product/259](url)

# Criterion for Success

1. Can go on tile, wood, AND carpet and alternate

1. Has a charge that lasts more than 10 min

1. Is maneuverable in all directions(not just forward and backward)

1. Can be controlled via remote (App)

1. Has a “cat-attractor”(feathers, string, ribbon, inner catnip, etc.) either attached to it or drags it behind (attractive appearance for cats)

1. Retains signal for at least 15 ft away

1. Eyes flash

1. Goes dormant when caught/touched by the cats (or when it bumps into something), reactivates (and changes direction) after a certain amount of time

1. all the “modes” worked as intended
