Object Detecting Line Follower Robot

Abstract

Line following robot is a robot car that can follow a path. The path can be visible like a white line on the black surface (or vice-verse). As a result of this line following property it has many applications in future and now itself. Lines following robot with pick and arrangement abilities are ordinarily utilized as a part of assembling plants. These proceed onward a predetermined way to pick the part from indicated area and place them on desired areas. Basically, a line-following robot is self-working robot that recognizes and follows a line drawn on the floor. The way to be taken is shown by a white line on a dark surface. The control system utilized must detect the line and move the robot to remain on course while always amending the wrong moves utilizing feedback mechanism, thus shaping a basic yet viable closed-loop system. As a software engineer you get a chance to "educate" the robot how to take after the line in this manner giving it a human-like property of reacting to stimuli. The robot has two sensors installed underneath the front part of the body, and two DC motors drive wheels moving forward. A circuit inside takes an info motion from two sensors and controls the speed of wheels' revolution. The control is done in a manner that when a sensor detects a white line, the engine backs off or even stops. Then the difference of rotation speed makes it possible to make turns.
