With the raising level of autonomous ability and intelligence, mobile robot has becomean important field of the robot technology. However, totally autonomous robot is difficult toachieve in many areas in application. Therefore, it is of great significant to design a remoteautonomous robotic man-machine system with the combination of the robot intelligenttechnique and remote operation technique when keep on raising the level of intelligence ofrobot. In this paper, the control technique of remote autonomous robot is studied.Firstly, the control system of remote autonomous robot is generally designed. A structureof double-layer control based on man-machine cooperation is design for the test robot. Inaddition, a variety of remote operation and the use of panoramic vision to the robot remotecontrol and monitoring of the implementation are generally designed. So the operator caneasily and intuitively control the robot.Secondly, the panoramic vision system is taken as the robot’s visual informationcollection tool, which can effectively solved when the narrow field of vision and lowcoverage of the issue. And the image is processed into perspective image that suit for personeye observation according to the principle of panoramic vision. The image is compressed fortransmission. The image information is preprocessed at the receiving end, enhancing theeffect, removing the noise.Thirdly, to the robot autonoment movement, design planning collision avoidancealgorithm based on the principles of A*algorithm, and solve the robot path planning problemin known environment. In addition, A fuzzy controller is designed for the obstacle avoidance.The robot detect the distance to the obstacle by the ultrasonic ranging system, and avoid it byfuzzy control rules, at last, verified through simulation algorithm.After that, to the communicate transmission, first of all, according to the Socketprogramming principle, the network communication platform is built. TCP and UDP protocolis used for the transmission of control command and video image respectively. Research onthe traditional control method, The joystick is used to send the control command in remotecontrol.So that, it can increase the teleoperator control method much more convenience andmake the operator presence.Finally, the autonomous obstacle avoidance experiment and remote operation assistedobstacle avoidance experiment is carried out for mobile robot. From the experiment, we canarrive that, the control system of remote autonomous robot could take the control technique of remote integrated into it. The design system could help the robot to finish the work very well.In the universe exploration, seabed development, military explosive ordnance disposal andother military or civil fields, the design system has important application value.
