The main content is the electric car pursuit design based on ultrasonic distance measurement circuit. The circuit is designed to calculates the distance around obstacle and the electric car by the ultrasonic distance function, Choose the best path forward, and use optical encoder detects the operation of the car running deviation angle, for the timely correction of the direction of the car in order to achieve self-drive car forward. Experimental results show that the set of simple and reliable design, with good controllability, to meet the design requirements.
