This paper presents sensor-based intelligent mobile robot navigation in unknown environments. The paper deals with fuzzy control of autonomous mobile robot motion in an unknown environment with obstacles and gives a wireless sensor-based remote control of mobile robots motion in an unknown environment with obstacles using the Sun SPOT technology. Simulation results show the effectiveness and the validity of the obstacle avoidance behavior in an unknown environment and velocity control of a wheeled mobile robot motion of the proposed fuzzy control strategy. The proposed remote method has been implemented on the autonomous mobile robot Khepera that is equipped with sensors and the free range Spot from the Sun Spot technology. Finally, the effectiveness and the efficiency of the proposed sensor-based remote control strategy are demonstrated by experimental studies and good experimental results of the obstacle avoidance behavior in unknown environments.
