Line Follower Robot: Design and Hardware Application

Robots are specially designed machines used to accomplish dedicated and repetitive actions with high speed, precision and endurance. These actions are mainly controlled by using advance programming, manipulators and sensors etc. The sensor based black line follower robots are one of the most basic robots used to follow black line on white background or vice versa. These robots may be used to in various industrial and domestic applications such as to carry goods, floor cleaning, delivery services and transportation. In this paper, a simple and cost effective circuit design of black line follower robot and its practical implementation has been presented.
