Internet-based Remote Real-time Tracking And Control System For Mobile Robot

Because of restriction of current condition in technique, it is impossible for mobile robot to complete tasks independently. So it is necessary for mobile robot to combine with human intelligence. Through human observing information on the jobsite and drawing working tactics, then the tactics are transmitted to the robot and finally carried out by the robot. Remote control technology that combined manual macro-control of local autonomous plays an irreplaceable role in hazardous environment condition, deep-water mining and space exploration, etc. High-speed broad-band's rapid growth and increasing provides inexpensive and relatively easily communications for remote control of robot. Real time tracking and supervise system of mobile robot based on Internet has further widened the application of remote control of robot, especially in remote medical treatment, long-distant education, supervisory control and maintenance of equipment and underground mining, etc.In this article, a new project of network application using J2EE components based on Java is presented, which develop the network application of control system. And the application of Struts in Web development is mainly discussed, the use of EJB in application logics design is described, the data consistency between application server and databases and the application of robot native control system with JNI are discussed.The system employs three-layered based J2EE structure and Web service, which enables the system to be more flexible, scalable and compatible. With J2EE and Web service techniques, remote control platform for mobile robot not only possesses the merits of two techniques and improves the scalability and reusability but also makes all members to pay more attention to the design and development on functions of the platform.Remote control platform of mobile robot is a distributed application system that is mainly divided into three structure modules, which involve Web server model is combined with layout part and logic part, application server module is combined with user management part and environment information sample part, and controller module is combined with native control part and communication part.At last, the control system is tested, the results show the system capacity is stable, and validates the feasibility and correctness of the system.
