Line Follower is an automated robot designed to follow a predetermined line as its path, usually a black line on a white surface or vice versa. Kakarobot Line Follower is a robot equipped with special sensors, usually infrared or optical sensors, that are able to detect color differences between the path and the surrounding surface. By using a microcontroller to process sensor data, this robot can adjust the speed and direction of the wheels to stay on the line, both when passing through sharp turns and smooth turns.
