Abstract: In view of problems of poor adaptability, communication ability and maneuverability of current mine robots, a mine rescue robot group was designed. The robot group mainly includes a communication robot, a search and rescue robot, an auxiliary rescue robot, and a data processing center. The communication robot uses UWB radar for life detection to find out specific location of trapped person, and at the same time guarantees information transmission during rescue process through built-in relay device. The search and rescue robot walks according to the real-time path and feedback audio, video, and underground environment information, and acts as a communication device after finding the trapped person, thus constructs a communication channel between the rescuer and the trapped person. The auxiliary rescue robot includes a wrecking robot which is responsible for getting through the rescue route and a material transport robot which is responsible for delivering rescue items to the trapped people. The data processing center plans search and rescue route of rescue robot through GIS according to position information of the trapped person, and correct the path according to underground real-time information. All kinds of robots in the robot group cooperate with each other, complement each other's functions, and unify the information, which can effectively reduce secondary damage caused by unclear environment after the disaster and improve rescue efficiency.
