SISTEM KENDALI KECEPATAN MOTOR DC PADA ROBOT MICROMOUSE

Micromouse robot is a robot that moves by Exploring the maze and stops when it has entered the goal area in the maze. Robot motion is in accordance with the speed that has been determined and the position of the robot against the wall in the maze. The system consists of hardware and software. The hardware consists of a series of microcontroller AT89S52, DC motors, DC motor driver IC circuit L298D, infrared sensor circuit with photodiode sensor and a series of LCD (Liquid Crystal Display). The microcontroller in the design software was created using BASCOM 8051. The robot will detect the wall, then the microcontroller receives data from the sensors, the data is processed in the microcontroller and the data from the microcontroller determines the direction of motion of the robot by sending logic to the DC motor driver L293D , The microcontroller will send data to the LCD and will be displayed in the form of alpha and numeric characters. The system has been implemented and can drive the DC motor in accordance with the desired speed using PWM mode ( Pulse Width Modulation ). LCD displays the direction and the robot motion data from sensors. Keywords: Robot Micromouse, Microcontroller AT89S52 and PW
