Design of an Intelligent Mini Car Based on AT80C51

Take AT80C51 microcontroller as the control core, an intelligent mini car is designed and the testing result on its function is given. The system adopts the infrared remote control to realize the startup and halt, and use the ultrasonic sensors to detect obstacles on the road. As a result, it can realize three major functions, such as Infrared remote control, avoiding hitting the barrier, digital display of driving time and mileage. The whole system has simple circuit structure and high dependability. The testing result meets the functional requirements.
