the experimental design using special trolley to AT89S52 microcontroller for the control of the core, Ultrasonic Range Finder to be detecting circuits, communications, LCD display, power supply circuits and other circuits. System consists of 89 S52 IO population control through the car back and forward to. Ultrasonic range finder is used to measure car in a closed space, the specific coordinates. Detection circuit used for the detection of coins, the communications system will be the first one car at a location coins pass second car, After a car will be based on the receipt of data automatically find the coins. In addition, the system will be measured through data LCD out.
