The robot was designed with a tracked system equipped with two DC motors.
HC-SR04 ultrasonic sensor was used for obstacle detection.
The sensor was mounted on a mini servo motor. Thus, the robot can look around to see the obstacles while it is moving.
The robot was powered by 6 AA alkaline batteries.
PIC16F628A was used as microcontroller for the robot.
L298 motor driver was used for the driving of the DC motors.
Motors were driven by differential drive system.
