F15: Autonomous Mobile

Abstract

Tesla Motors just announced their own developed technology on the October 14, 2015 - Autopilot on all of their currently supporting vehicle Model S. Using some of the top-of-the-line industrial sensor - a forward radar, a forward-looking camera, 12 long-range ultrasonic sensors, and a high-precision digitally-controlled electric assist braking system, an automated driving capabilities luxury car is being delivered. All of those feedback modules were being involved differently in the autopilot system. With a similar concept on the self-driving capability model RC car, our team is going to deliver similar technology with the knowledge on different peripheral drivers.

Objectives & Introduction

This program is target to deliver a self-driving vehicle with GPS/compass module and bluetooth communication with Android. Obstacle avoidance will only be added if time is permitted. The below are the tasks we aim to deliver: Motor and Servo, GPS, Compass, and Bluetooth enable.

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?
