Project Title

Self-navigating RC car based on CAN communication.

Abstract

Embedded Systems are used to take real world input and covert it into the data that can be processed to monitor,control or obtain desired results. In this project , we aim to design and develop an autonomous self-driving RC car that navigates from the current location to the destination location that is selected through an Android application, avoiding all the obstacles in the path. The car comprises of 5 controllers communicating with each other over the CAN Bus, each having different functionality.

Introduction

The project was divided into 5 modules:

  • Sensor Controller: This module detects obstacles in the driving path with the help of ultrasonic sensors.
  • Motor Controller: This controller drives the DC motor and Servo in the car.
  • Geographical Controller: This module assists the car in navigating to a destination with the help of location details provided by GPS and the

orientation(bearing and heading angle) provided by the compass.

  • Bluetooth Controller: The controller uses Bluetooth to communicate with an Android application on the Android phone. Destination coordinates are provided by this module. The Bluetooth module also displays important data like Ultrasonic sensor values, GPS coordinates and speed.
  • Master Controller: This module will collect data from all modules and direct the motor module towards the destination.
