Project Title
Abstract
The purpose of this project is to implement a robot car which will follow the path drawn on the touch screen.
Objectives & Introduction
- The prime objective of this project is traversing a robotic car autonomously through specific map or grid,depending upon the points drawn on the touchscreen.SJ-ONE board is used giving control signals to motor driver IC and communication between user interface and car. communication between 2 boards is implemented by Embedded baseband wireless protocol using a on-board NORDIC wireless chip .Obstacle sensors are used to detect obstacles and avoid collision.
- Focus of project was to make an Real-time system/application using touchscreen and SJ-ONE development board which could guide and navigate a vehicle through a specific or predefined area.
