The purpose of this document is to help you build a Line Following Robot.

Starting with an overview of the system the document would cover implementation details like circuits and algorithms, followed by some suggestions on improving the design.

The ‘Reference and Resources’ page has a list of relevant books, websites, electronic shops and commonly used parts & their prices.


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.
(A course on Digital Design and Electronic Devices & Circuits would be helpful)
C Programming
Sheer interest, an innovative brain and perseverance!
