The Line Follower Robot is a simple machine, designed to be able to detect and follow the line drawn on a path without getting off the line too much. This path can be either visible like a black line on a white surface or invisible like a magnetic field. This Robot should sense the line with its 8-Infrared Ray (IR) sensors that have installed under the body. When that happens, the circuit inside takes the input signals from the sensors and controls the speed of wheels’ rotation by transmitting the data to the processor by specific transition buses. Then, the processor is going to decide the proper commands and then it sends them to the driver then the motor slows down or even stops. Then the difference of rotation speed makes it possible to make turns, and thus the path will be followed by the line follower robot.
