The Line follower and Obstacle Avoiding robot is basically a kind of robotic machine that can recognize and adhere to the contrasting-colored painted line on the floor. In most cases, the track is predetermined and can be seen as a black line on a white surface or a white line on a black surface, or any two highly contrasting colors. Hence, the Robot of this kind should detect the line with the help of Infrared Ray (IR) sensors that mounted in the front of robot facing down. The robot also detects obstacles and avoid them according to the requirements. We use Arduino board which makes our task much easier to dump the code and run the machine. The data is relayed to the hub by dedicated transmission cables. Therefore, the hub that contains the main processor will be deciding the required commands and then it relays the information to the to the Motor driver Shield and hence, The route will be taken by avoiding the obstacles on the way if any by the Line Follower and Obstacle avoiding robot.
