A line follower is a self-operating robot that detects and follows a line that is drawn on the floor. The path consists of a black line on a white surface (or it may be reverse of that). The control system used must sense a line and maneuver the robot to stay on course, while constantly correcting the wrong moves using feedback mechanism, thus forming a simple yet effective closed-loop System. The robot is designed to follow very tight curves.
The path is a black line on a white background with a width of 3 cm (except at bend where a little variation may be present). It may contain paths laterally displaced around 3 cm and also at a gap of around 5 cm. The robot is designed using two motors controlling wheels. It has infrared sensors on the bottom for detecting black tracking tape. It captures the line position with the help of these IR-photo diode sensors mounted at the bottom end of the robot.
The basic operation of the line follower is that it captures a line position with the IR sensors mounted at the front end of the robot. For this purpose, a combination of IR LEDs and Photo Transistor are used. The line sensing process requires high resolution and high robustness.
Line follower robot is useful in many places like ware houses, industries, stores, etc., where it follows a dedicated path. This proposed system of a line following robot fulfils the desired functionality, and demonstrates the working of it.
In the future this project can be heightened by using a microcontroller to add astuteness to the robot by writing appropriate program.
