Summary: This paper focuses on the control of wheeled mobile robot subject to bounded disturbances. A tracking controller for the mobile robot was developed by considering its kinematic model and Euler-Lagrange dynamics. Type-2 fuzzy logic is proposed to synthesize the controller for the overall system via backstepping methodology which is claimed to be a robust tool for related applications. A systematic procedure to satisfy required time responses for stabilitzation of the kinematic model is made through genetic algorithm approch. Simulation results are presented confirming the performance of the tracking controller.
