A multi-function intelligent car with an 8-bit microcontroller Mega128 is introduced,which has the functions of tracing,metal detection,obstacle avoidance,phototaxis and range finding. This multi-function intelligent car system adopts modular control and can track the route precisely by embedding the fuzzy control algorithm. This car is able to bypass obstacles by the ultrasonic detection. The phototactic system with adjustable sensitivity was designed to drive the car into its garage. The metal sensor in this car is used to detect metal blocks and Hall device is used to measure the car’s driving distance. Finally, the number of metal blocks,running time and driving distance are displayed in a LCD screen to realize the friendly human-ma-chine interface. The experiments show that the intelligent car system can complete the specified functions and achieve high sta-bility and accuracy on each independent control module.
