A fuzzy system for indoor mobile robot navigation

An autonomous mobile robot has to cope with uncertain, incomplete or approximate information. Moreover, it has to identify sudden perceptual situations to manoeuvre in real time. This paper describes a fuzzy rule based system (FRBS) approach for controlling the movement of an autonomous mobile robot (MORIA). Difficult guiding and controlling properties of the robot are achieved by combining local actions and global strategies within the fuzzy controller. Different behaviors and perceptions are detected with the help of fuzzy rules and stored in fuzzy state variables. These state variables activate different fuzzy rule sets which in turn change the behavior of the fuzzy controller
