This micro controller line follower robot is designed to be able to follow a black line on the ground without getting off the line too much. 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 input signal from two sensors and controls the speed of wheels’ rotation. The control is done in such a way that when a sensor senses a black line, the motor slows down or even stops. Then the difference of rotation speed makes it possible to make turns. For instance, in the figure on the right, if the sensor somehow senses a black line, the wheel on that side slows down and the robot will make a right turn.

What is a line follower?

Line follower is a machine that can follow a path. The path can be

visible like a black line on a white surface (or vice-versa) or it can be

invisible like a magnetic field.

Why build a line follower?

Sensing a line and maneuvering the robot to stay on course, while

constantly correcting wrong moves using feedback mechanism forms a

simple yet effective closed loop system. As a programmer you get an

opportunity to ‘teach’ the robot how to follow the line thus giving it a

human-like property of responding to stimuli.

Practical applications of a line follower: Automated cars running on

roads with embedded magnets; guidance system for industrial robots

moving on shop floor etc.


Knowledge of basic digital and analog electronics.

C Programming Sheer interest, an innovative brain and perseverance!

        WHY YOU USED 12MHZ ?

        • IQBAL SINGH

          Its not necessary to use 12MHZ, you can use anyone within its limit. It can decrease or increase processing speed accordingly decreasing or increasing frequency.
