The wheels are attached to the DC geared motors to provide mobility to the robot. They convert the rotational motion of the motors into linear motion, enabling the robot to move forward, backward, or turn. In this kit, plastic or rubber wheels are usually provided for better grip and smooth operation on different surfaces. Proper alignment of wheels is important to ensure the robot moves straight without deviation. The size of the wheels also affects speed and stability. Combined with the motors and chassis, wheels play a crucial role in determining the robot’s movement performance.
