Abstract：This design finished a robot with many functions based on single chip microcomputer and many kinds of sensors. 89C51 is the core of the system, achieving the intelligent control of the robot. Reflected infrared photoelectric sensors can detect the leading line, to make the robot go alone the path all by itself. Using the chip named “Hall IC”, to measure the distance by counting the wheels that the robot has run. Another sensor named “approach switch” can detect metals that embed in the path, and give alarms both sound and light. the robot can show the direction of the metal, tell us how long it is away from the jumping-off point.
