Abstract:A semiautomatic trackedrobot suitable for subway was designed, that was used for scene environmental perception and emergency disposal. According to the characteristics of subway station scene, the trackedrobot could climb freely the stairs up and down, and sample for unknown substances and explosive object disposal (EOD). Moreover, the scene environmental condition was obtained by remote monitoring (RMON), and the existence of poisonous, flammable and explosive gas was also detected in the air. The trackedrobot could implement convenient rescue of persons to avoide secondary lossses. The feasibility of the robot is verified through experiments.
