Design and Construction of Line Following Robot using Arduino

Line following robot is an autonomous vehicle which detect black line to move over the white surface or bright surface. In this paper, the line following robot is constructed by using Arduino nano microcontroller as a main component and consists of three infrared IR sensors, four simple DC motors, four wheels and a PCB frame of robot chassis. The infrared sensors are used to sense the black line on white surface. When the infrared signal falls on the white surface, it gets reflected and it falls on the black surface, it is not reflected. In this system, four simple DC motors attached with four wheels are used to move the robot cars direction that is left, right and forward. The Arduino nano is used as a controller to control the speed of DC motors from the L2953D driver circuit.
