Abstract: Aiming at the problem of difficulty and high cost in complex region detection, a quadruped crawling robot and remote monitoring system with autonomous cruising function based on GNSS are designed. Then robot uses the embedded STM32F429IGT6 chip as the main control CPU, and carries the GPS／BeiDou positioning module and wireless communication module. So that the robot can realize autonomous cruise and automatic adjustment of the route. The robot is equipped with a variety of sensor modules to achieve the collection of environmental temperature, humidity, wind speed and other parameters. At the same time, the collected data are analyzed, processed and transmitted. The monitoring system based on this function can realize the real-time monitoring of the robot, including the motion track and position information, and send control instructions to the robot through wireless network, which has the function of remote control. The experimental results show that the autonomous cruise robot and its monitoring system can achieve accurate positioning and realtime route adjustment, and improve the accuracy of robot detection.
