The wheels are essential mechanical components that provide motion to the Line Following Robot. They are attached to the BO motors and convert the motor’s rotational energy into movement. Properly sized wheels ensure stability, smooth rolling, and better traction on the surface. In robotics, the choice of wheel size and grip directly affects performance. For line followers, lightweight plastic wheels with rubber grips are commonly used to avoid slipping during sharp turns. The wheels, combined with accurate motor control, ensure the robot maintains its path on both straight and curved tracks, improving navigation and efficiency.
