For the car in motion the process of tracing requirements, designed to AT89C51 microcontroller as the core of the control circuit, the use of modular design, the use of color sensors, metal detector sensors, ultrasonic sensors, Hall sensors of different detection circuit, track to achieve the car in motion, detection of embedded metal plate, avoid obstacles, such as measuring the speed problem detection, and circuit design of the theoretical analysis and practical testing. The results show that the smart car has a good ability to identify and detect, with positioning accuracy, stable and reliable characteristics
