This document describes the development of an autonomous mobile robot for wall following using a fuzzy incremental controller. Two ultrasonic sensors are used to sense the distance to the wall and provide input to the controller. The controller determines the speed of two DC motors to guide the robot along the wall. Experimental results showed the fuzzy controller successfully controlled the robot to follow the wall, performing better than a PID controller. The robot is intended for applications like cleaning air ducts or corridors by autonomously navigating while maintaining a set distance from the wall.
