Model RC

Tesla Model RC


Abstract

Tesla Model RC is an electric, battery-powered, self-navigating RC car. The aim is to navigate to the destination set on the Android application by utilizing GPS navigation. The car combines the data received from multiple sensors to perceive its surroundings to avoid obstacles in its path.

Introduction

The project was divided into 5 modules:

  • Bridge and Sensor Controller
  • Motor Controller
  • Geographical Controller
  • Driver and LCD controller
  • Android Application
