Advances in automation technology reduce the need for human. Although technological machines have relatively high costs but their operation and maintenance cost is low. The errors caused by human are eliminate using this type of machines. In this study, a motor drive system is developed for the vehicle follows the given route. When the command is given the vehicle moves and acts like a human without hitting obstacles on the road.
In the vehicle a permanent magnet dc motor is used. Four quadrant control of the dc motor is performed based on microcontroller. The average voltage value of the H-bridge converter is changed by PWM signal generated by micro-controller so that the motor speed is controlled.
