Project Title

  • Autonomous RC Car

Abstract

The self-driving RC car navigates autonomously from a source point to destination avoiding obstacles. It consists of five micro-controllers namely Motor & I/O, Sensor, Geo, Communication Bridge & Android and Master performing specific tasks.

  • Motor & I/O Controller - This controller takes care of driving and steering with the help of motors and displaying the status of car on the LCD.
  • Sensor Controller - Obstacle detection and avoidance will be taken care by this controller.
  • Geo Controller - Orientation(heading and bearing)and navigation of the car on a specified path will be determined by this controller.
  • Communication Bridge & Android Controller - Co-ordinates for navigation are provided by this controller using an android application communicating with Bluetooth.
  • Master Controller - This collects the data from rest of the controllers and guides the car.

These five controllers are connected to five SJ One boards. Communication between all the five controllers is established using CAN bus.

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.
