Design Of Embedded Robot Obstacle Avoidance With Wireless Communication Function

With the development of information technology,embedded technology and mobile communication technology,mobile robot applications more and more widely,including detection of harmful substances,mine,chemical dangerous goods shifting,and home life of the elderly care,indoor environment monitoring etc..Received widespread attention from all walks of life.The main content of this paper is to design a mobile robot with the ability of autonomous obstacle avoidance,which consists of the body,sensors,power systems,wireless communication systems,and control systems.Through consulting the literature data,we found several kinds of techniques used for the autonomous obstacle avoidance of therobot.On the basis of the comprehensive analysis of the various techniques,this paper decided to design a fuzzy algorithm to avoid obstacles.The following is the main work of this paper:1.The various subsystems of the robot are analyzed,and the design of the hardware and software system of the robot is completed;2.Selecting the appropriate wireless networking mode to designed the wireless communication system that uses of the information interaction.Using the way of this paper,the Qt interface program is designed to test the wireless communication system,which verifies the reliability of the communication system.3.Aiming at the dead zone of the mobile robot obstacle avoidance,in this paper,we use the method of setting up a variety of sensors to accurately collect the information of the obstacles.Multi direction and multi sensor acquisition method,eliminating the robot detection blind area,and improve the detection accuracy.And then accordingto the actual situation of the environment of the robot with distribution of sensors on the robot,the robot's perception of the external environment is divided into 11 classic environment types according to the type of environment settings set corresponding fuzzy control rules.Robot using sensors,wireless communication systems,geomagneticdetection module and other information obtained with the establishment of fuzzy rules for comparison,and then the robot to make the appropriate action to achieve autonomous obstacle avoidance.Finally,the control algorithm of the robot is simulated by Matlab,which verifies the validity and reliability of the control system.In the physical experiment of the robot,the obstacle avoidance ability of the robot is tested.
