Design and Implementation of an Autonomous Car for Navigation in Unknown Enviornments

The paper describes the design and development of an intelligent autonomous vehicle that can navigate without human operator in unknown environments. We have interfaced to AT89C52 microcontroller with the ultrasonic sensors and GPS receiver for easy access to the destination by avoiding the obstacles in its way at low level. A camera is interfaced to pc for lanes’ identification and road following task at higher level. The designed vehicle has modular structure and more modules can be added without much complexity. The experimental results demonstrate the effectiveness of the proposed design
