Project Title
LightFury
Abstract
LightFury is an autonomous electric car project that aims to bring different embedded system paradigms together and consolidate them with industry level sophistication and robustness. This project will feature an RC car which will employ different sensors and motors to navigate the track. Every sensor/motor combined with a dedicated functionality is managed by a controller. Such different controllers will communicate with the master node using the CAN protocol.
Introduction
The project was divided into 7 modules:
- Master Controller
- Motor Controller
- Sensor Controller
- GPS Controller
- Android application and Bluetooth Connectivity
- Hardware (PCB designing)
- Testing

Planned a single PCB to place and route CAN transceivers and eliminate dangling wires.
CAN Communication
With the help of CAN transceivers, each sensor module sends data in DBC format to the controller. The data from ultrasonic sensor helps in obstacle detection. The GPS and Compass Module helps with navigation. The LCD gives live information of component status and values. Finally there is motors and control unit for navigating the car as per the controller commands.
