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

Bridge functionality of the Bridge and Sensor Controller is to establish wireless communication between the SJ-2 Board and the android mobile device using the HC-05 Bluetooth module. The Bridge controller will be receiving start command with destination geo coordinates and stop command. The Bridge controller will be transmitting the required sensor data and debug information to be displayed on the android application.

Advise for Future Students

• Form your team and start the project as early as you can.
• Clearly discuss what role each individual should do and ensure that progress is regularly tracked so that the team doesn't fall back on any schedule.
• Since lot of code and hardware integration is involved with this project, make sure testing is thoroughly and periodically done and make note of all the issues found.

HARDWARE:

• Decide on how you would power up the peripherals. We had issues with Bluetooth (not connecting), GPS (lock not happening) and LIDAR (giving incorrect values). After lot of cycles of hardware and software debugging, we found that the issue was with power. Choose wisely as to which peripherals must be connected to which power bank.
• Start with PCB as soon as possible, and expose some extra GPIO and GND pins for future use.
