Project Title

Team X


Abstract

Our main goal of this project was to utilize the knowledge acquired from the lectures in CMPE 243. The report summarizes the overall process taken to develop an autonomous driving RC car using FreeRTOS, various periodic tasks, and the CAN bus to combine and run the different code modules.

Introduction

The project was divided into 5 modules:

  • Sensor Node
  • Motor Node
  • Driver Node
  • Geo Node
  • Mobile Application

Technical Challenges

< List of problems and their detailed resolutions> The main issue we had with the motor controller occurred during PWM hacking because we did not want the motor running the car too fast. As such, we had to guess and check a good PWM value to run the motor so that the car would move at the slowest speed possible without running into issues where it could not move. However, with continual tests, we managed to identify the ideal range that we wanted to run the motor at.
