A design of fuzzy control for line following together with distance keeping on wheel robot

This paper presents a controller design of line following together with distance keeping based on fuzzy logic for application of automatic guided vehicle. We implement the design in wheel robots. The line following detection sensor is an array of infrared light sensor. The distance detection sensor is an ultrasonic ranging finder. The line-following control and distance-keeping control are directly combined to drive the servomotor of wheel robot. Performance is examined on an Stype orbit.
