Base on the microcontroller 89c52, the mini-car can race intellectually by detecting the black guide-line, then dodge the barriers and finally reach the destination. The system adopts photo electronic sensors to control the direction, search barriers and the light source precisely. By introducing the PWM and the HALL speed sensor, the car can measure the distance accurately while running at different speed. Guided by a unique software algorithm, the car dodges barriers and reaches the garage easily.
