Abstract: For the problem that existing disaster rescuing robots cannot adapt to disaster environment of coal mine underground, a novel information exploration robot system for mine disaster was proposed. Distribution of the system in underground was introduced as well as designs of its structure and control system, and climbing ability of disaster rescuing robot in the system was analyzed. The robot moves along I-beam track of overhead monorail in underground and arrives disaster field quickly when disaster happens to collect and send image and environment information to command center on the ground. Test results in simulated coal mine roadway show that the system runs stably and transmits image clearly and continuously, and climbing angle of the robot is 18.5°.
