Research of intelligent mobile robot's obstacle avoidance based on ultrasonic sensor

Abstract

One of the most active research topics is intelligent mobile robot which is the important direction of robot research.With anal-yzing many sensors used in intelligent mobile robot's obstacle avoidance,a fuzzy algorithm of obstacle avoidance with multi-ultrasonic sensor is proposed.The obstacle avoidance is detailed based on ultrasonic sensor's rule of fuzzy control and courses of defuzzification,and the experimental result is produced.The experimental result indicates that fuzzy control mechanism and tactics is easy to being ac-cepted and suitable,the application of fuzzy algorithm has the very largely compatibility to the environment,and the robot's avoidance can be achieved under the different environment.
