Design Of Service-type Mobile Robot Control System Based On Gsm And Zigbee

With the progress and development of the society and people's living standards, the robots which can complete some simple work instead of human being as well as communicate with people have become more and more popular. Now it has become another research focus following industrial robot.Because the service-type robot is mainly oriented to general people, a friendly man-machine interaction mode is a primary problem. As mobile communication technology develops fast, expenses has been reduced year by year, it is obvious that mobile phone is very suitable to be used as a remote controller of the robot. But when the operator is relatively near to the robot, the communication between the robot and mobile phone is wasted. The short-range communication can remedy this defect. At present, there are many short-range communication modes, for instance infra-red, bluetooth, ZigBee etc. Each of these modes has their own characteristic. Considered the respects of various aspects, ZigBee technology is adopted in the design.The purpose of this subject is to build up a multi-purpose service-type mobile robot which can be used in the environment such as family, supermarket, restaurant etc. The motion model is established in the paper. The control system and the wireless communication function of the robot have been mainly studied in the design. According to the overall design proposal and module design style, the paper introduced the design of hardware and software about the MCU module, sensor module, motor driving, power module and wireless communication module including GSM (Global System for Mobile Communication) and ZigBee module etc. The short message function of GSM module and group network function of ZigBee module is introduced especially. The ZigBee network includes robot, PC and romote-controller three nodes, among which the robot is used as a coordinator. And on the PC, the graphical user interface is developed through the serial interface of VC++6.0. The feasibility of ZigBee network has been examined.Finally, has been made a summarization of all the work and prospective of the future job.
