A sarin gas incident occurred in the Tokyo subway system on March 20, 1995. This fatal gas attack caused sicknesses to many passengers. Since the disaster broke out under the ground, the main job of rescue personnel was to transport victims on stretchers to a first-aid station on the ground. So, we research and development the rescue support stretcher system (robot) for a heavy casualty disaster in underground areas or at stations can be handled in a quick, effective manner. The stretcher robot is expected to help firefighters achieve efficient rescue operations. In this paper, we describe the produced stretcher robot. And, we evaluate that stretcher robot can transfer a victims by the experiment.
