Abstract

The main objective to develop Automated Guided Vehicle, AGV, for PSM is to construct a prototype of vehicle that can direct itself by following the program. The microcontroller 8051 model is used as AGV main controller which has variety of input devices and output devices. This prototype has two back wheel driven by a DC motor as main drive motor and two front wheels driven by a DC motor as steering motor. Both of the motor can change their direction by using the motor driver called H-bridge. In AGV operation system, the AGV loading goods and follow the track from one station to another station inspected by photomicrosensors. The photomicrosensor will generate the signal proportional to the strength of the image that the sensor detected and the image would become input signal to microcontroller. The microcontroller processed the signal and send information to the DC motors as an output. For collision avoidance,ultrasonic sensor will used to detect the obstacle. With this ultrasonic sensor, the AGV will stop automatically if there is any obstacle appeared in front of vehicle. In case of emergency, the radio frequency remote control is used to stop the vehicle.
