Fuzzy logic based wall tracking controller for mobile robot navigation

Abstract

This paper describes the design and implementation of a fuzzy logic based controller for wall tracking behavior of mobile robot. The controller accepts inputs from three ultrasonic sensors and generates speed commands for differentially steered robot to track wall on its left side at a set distance. The controller is implemented in real time using an inexpensive 8 bit microcontroller and is validated through experimental runs in following the corner trajectory.
