In order to better control the hexapod bionic robot to adapt to the wild fieldwork environment, a new solution of wireless field positioning system of the hexapod bionic mitigation rescue robot is proposed in connection with the problem of robot field positioning. In this paper, we design a bionic robot field positioning system by using the Samsung S3C2440 microprocessor as hardware platform and the embedded Linux system as software platform. The hexapod bionic robot is positioned by GPS global positioning system and the location information is transmitted to the terminal equipments by using the GPRS network communication. Then the terminal equipments send commands to control hexapod bionic robot to achieve the appropriate actions. Experiments show that, this system has good stability and high reliability. It can better meet the needs of field positioning of the hexapod bionic mitigation rescue robot.
