Line follower is an autonomous robot which follows either black line in white area or white line in black area. Robot must be able to detect particular line and keep following it.
For special situations such as cross over’s where robot can have more than one path which can be followed, predefined path must be followed by the robot.
Line following is a task in which robot has to follow the line. It must be capable of taking various degrees of turns to follow the curved lines also.

The Line following Robot moves to follow a line drawn on the floor. This Robot follows the black line which is drawn over the white surface .The line sensors are used to sense the line. When the signal falls on the white surface, it gets reflected and if it falls on the black surface, it is not reflected this principle is used to scan the Lines for the Robot.
The Robot should be capable of taking various degrees of turns and must be insensitive to environmental factors such as lighting and noise.
