WALL FOLLOWING ROBOT
In today's project we have built a wall-following robot. It consists of two Infrared sensors. One on the left to detect the wall by its side and other in the front to detect when to take a turn. Our robot follows a simple closed loop to carry out the designated function.
Providing it with PID(proportional-integrated-derivative) control will exponentially increase the smoothness of operation and will be able to handle complex turns. But, that would require an Ultrasonic sensor rather than an Infrared one.
When placed near a wall, it will continue moving along the wall keeping it on the left unless it gets an obstacle when it backs up a little, takes a right turn and continue as before.
