On nowadays, the development of robot's technology is rising rapidly and it has been applied in many fields such as national defense, aerospace, electricity and industry.
The artificial intelligence vehicle is an example of robot. The design of the artificial intelligence vehicle has covered many knowledge fields such as machines, cars, electronic technology, automatic control, computers and sensors. The system of the design uses the STC12C5A60S2 SCM as CPU. The chassis of car is bearing the control system and the sensor system. The H bridge circuit is the power of the car. The car has infrared sensors which make it seek road and avoid obstacles. The control system and sensor system are arranged with the circuit design software which also draw the diagram or circuit principle.
