CAN-STER TRUCK LOGO

Abstract

The CAN-STER Truck Project is an autonomous RC car with CAN Bus interfaced controllers. The development of the RC car's subsystem modules (Interfacing of Ultrasonic Sensor, LIDAR, Bluetooth, GPS, and CAN modules) was divided among six team members. The aim of the project is to develop an autonomous RC Car which can navigate from the source location to a selected destination by avoiding obstacles in its path using sensors and motors.


Introduction and Objectives

The project was divided into 7 modules:

  • Bridge and Sensor Controller
  • Motor Controller
  • Geological Controller
  • Driver and LCD Controller
  • Hardware Integration
  • Android Application
  • Testing & Code Review

RC Car Objectives 

     1. Driver and LCD Controller - Handles algorithms for obstacle avoidance, route maneuvering, and waypoints
     2. Geological Controller - Recieves coordinates from GPS and Heading from Compass for navigation 
     3. Motor Controller - Controls movements of the RC Car 
     4. Bridge and Sensor Controller - Detects surrounding objects and interfaces android application to controller via bluetooth
