The Research on Intelligent Mobile Robot's Avoiding Obstacle by Ultrasound

Intelligent mobile robot is an important research direction of the robot field, and it is one of the most active research themes. In this paper, on the analysis of the commonly used sensor in intelligent mobile robot obstacle avoidance, the ultrasound obstacle avoidance system of mobile robot is proposed based on multi-ultrasonic sensor. The fuzzy control rules and defuzzication of the ultrasonic obstacle avoidance system is introduced, and the experimental results are given. The experimental results show that the fuzzy control mechanism and strategy are easy to be reception and understood, and are facilitated to be applicable and developed. The fuzzy obstacle avoidance algorithm is very adaptive to the environment, so the robot has achieved the obstacle avoidance in different environmental conditions.
