Research On Mobile Robot Obstacle Avoidance Strategy Based On Multi-sensor

With the development of modern information technology, the application of mobilerobot not only involves the fields of industry and agriculture, medical treatment, serviceindustry, but also extends to the fields of urban safety as well as space exploration. Inrecent years, obstacle avoidance based on multi-sensor information fusion of mobile robothas caught widespread attention from domestic and international scholars. At the sametime, it becomes one of the important research directions in the last few years. TheObstacle avoidance technology of mobile robot mainly depends on its sensor equipment tosense the distributions and distances of obstacles, and then steer clear of obstacles.This article introduces the development situation as well as the related applicationinformation of mobile robots, showing the essential methods in processing of related visualimages, which focuses on digging a deep research into the strategies of obstacle avoidance.At first, making a position analysis on obstacles precisely and reliably, which is animportant process to make the mobile robot avoid obstacle successfully. With visualtechnology and infrared sensor, the obstacle avoidance system of mobile robot absorbs theadvantages of both, ensuring the real-time, effectiveness of information collection,especially providing the observation, collection and location accuracy of goods withconvenient condition. Above all, we could see the development of information fusiontechnology of sensor will bring about better research prospect for the field of mobile robot.The Obstacle avoidance technology will develop towards a more capacity, more accuracyand more speediness direction.For the process of obstacle avoidance behavior of mobile robot, we make a design byresearching control algorithm, connecting with information fusion technology, making surethe category of obstacles, and then taking different actions to avoid it. Finally we couldmake the mobile robot walk out of this route without any collision, which shows the wholeprocess for mobile robot to avoiding obstacle. Depending on the different condition in thewalking program, we could divide the walking behavior of the mobile robot into thebehavior of proceeding straight to the target, behavior of direct avoiding obstacle, behavior of walking along the wall and also behavior of urgent avoiding obstacle. At last, in theindoor environment, we make an experiment and analysis of mobile robot and also checkthe effectiveness of the method we put forward.
