Vision RC Car

Abstract

The goal of the Vision RC Car is to be able to roam wherever a WiFi network is present. A user will utilize a web-based GUI to view a video-feed from the platform, and in turn control the vehicle from the GUI.

Objectives & Introduction

The Vision RC Car, here on out known as the system, was initially designed to spy on people. A user will have the ability to access a video-feed from the system, in addition to the ability to control the speed and direction of the system through the web-based GUI. It was determined that in addition to any nefarious activities that could be conducted with the system, a user could also utilize the system to make deliveries of small packages, to explore spaces inaccessible to humans, and for hobbyist purposes.

The system is composed of a gutted RC car, a dual-bridge motor controller, the SJSU One microcontroller, the Intel Edison microcontroller, and a webcam. At the center of the system is the Edison, which runs a lightweight Linux distro known as Yocto. The Edison is WiFi capable and will serve as the system bridge to wireless networks. The Edison will run a Node.js server that will host the system GUI. The webcam is interfaced with the Edison, and the video-feed is presented on the GUI. The system will utilize JavaScript to read commands from the user, and redirect the commands received to the SJSU One.

The SJSU One and Edison communicate through UART at a baud rate of 115200. The SJSU One will control the speed and direction of the system by interfacing with the dual-bridge motor-controller, which in turn drives the two-motors of the system. One of the motors is responsible for forward and backward movements, while the other motor is responsible for steering.

Schedule

Show a simple table or figures that show your scheduled as planned before you started working on the project. Then in another table column, write down the actual schedule so that readers can see the planned vs. actual goals. The point of the schedule is for readers to assess how to pace themselves if they are doing a similar project.

Week# Start Date End Date Task Status Actual Completion Date

Parts List & Cost

Give a simple list of the cost of your project broken down by components. Do not write long stories here.

Design & Implementation

The design section can go over your hardware and software design. Organize this section using sub-sections that go over your design and implementation.

Hardware Design

Discuss your hardware design here. Show detailed schematics, and the interface here.

Hardware Interface

In this section, you can describe how your hardware communicates, such as which BUSes used. You can discuss your driver implementation here, such that the Software Design section is isolated to talk about high level workings rather than inner working of your project.

Software Design

Show your software design. For example, if you are designing an MP3 Player, show the tasks that you are using, and what they are doing at a high level. Do not show the details of the code. For example, do not show exact code, but you may show psuedocode and fragments of code. Keep in mind that you are showing DESIGN of your software, not the inner workings of it.

Implementation

This section includes implementation, but again, not the details, just the high level. For example, you can list the steps it takes to communicate over a sensor, or the steps needed to write a page of memory onto SPI Flash. You can include sub-sections for each of your component implementation.

Testing & Technical Challenges

Describe the challenges of your project. What advise would you give yourself or someone else if your project can be started from scratch again? Make a smooth transition to testing section and described what it took to test your project.

Include sub-sections that list out a problem and solution, such as:

My Issue #1

Discuss the issue and resolution.

Conclusion

Conclude your project here. You can recap your testing and problems. You should address the "so what" part here to indicate what you ultimately learnt from this project. How has this project increased your knowledge?

Project Video

Upload a video of your project and post the link here.

Project Source Code

References

Acknowledgement

Any acknowledgement that you may wish to provide can be included here.

References Used

List any references used in project.

Appendix

You can list the references you used.
