Abstract
A disaster relief robot can be prevented from falling over a precipice or the like while safety for the operator can be ensured during outdoor field transportation of relief supplies such as rescue apparatus and materials, medicines or food stuffs in the case of a wide-area disaster caused by an earthquake, a heavy rainfall, a landslide or the like. Accordingly, track frames (16) for crawlers (12) are pivotably attached to a robot body (10), respectively, at its front and rear ends, the distance L between the pivot shafts of the front and rear crawlers (12F, 12R) is set so that maximum pivoting loci (CF, CR) of the crawlers do not interfere with each other, and further, the gravitational center (G) of the robot body is set at a position intermediate of the distance (L) between the pivot shafts of the front and rear crawlers. Several kinds of operation controllers are also provided.
