Roadster

System Design

Abstract

Roadster is a battery powered autonomous car, that drives itself to a specified destination and avoids any obstacles that comes its way. The car infrastructure has four Nodes (Geo, Sensor, Driver and Motor) that communicate over the CAN bus and an android application interface to set the destination location. In order to make an informed decision the car processes Geo and Sensor Node’s data which is used to steer the car in the right direction.

Introduction

The project was divided into N modules:

  • Sensor ...
  • Motor..
  • ...
  • Android

Mobile Application

<Picture and link to Gitlab> We created a lightweight mobile app to control our car, It can communicate with the car via Bluetooth and is capable of sending Destination co-ordinates along with checkpoints. Receive and Update live location on Google Maps, send Start, Stop and Clear commands, Receive and Display Debug Data. This app has mainly two activities, The main activity and maps activity.

Maps Activity

This is the only functional activity for the app and is responsible for the Google Map related Tasks and Bluetooth Tasks.
