Implementation of autonomous line follower robot

Abstract

The line follower is an autonomous robot that detects and follows a line. The path may be visible like a black line on a white surface or may be reverse of that or it can be invisible like a magnetic field. A close loop control system is used in the robot. The robot must sense a line and maneuvers accordingly to stay on course while correcting the wrong moves using feedback mechanism thus forming a simple but yet effective closed loop System [1]. The robot is designed to follow very tight curves as the data from the sensors are continuous in nature. This robot is simple but effective having straightforward design to perform line following task.
