S24: Team X

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
