An approach to distance and motion tracking control investigated from the viewpoint of the cooperative behaviour of autonomous robots is presented in this paper. A fuzzy control-based solution using laser alignment and ultrasonic distance ranging techniques as inputs to a two input, two output, non-linear controller is the major focus of this paper. The solution uses a fuzzy-controller to control the orientation and speed of a differential drive robot to maintain distance and motion tracking control with respect to a robot in front of it. The fuzzy controller has been fully implemented on an 8-bit microcontroller, using S-type, Z-type and Lambda-type membership functions, MAX/MIN inference and CoM defuzzification methods.
