(54)Crawler robot


(57) Disclosed is a crawler robot which, even of a small size, can climb over a high step and which can perform various aspects of operations. Rollers, are arranged at apexes of triangular frames, and elastic crawlers are wrapped around the rollers, with the two frames being connected by a central support shaft. Rotatably provided to the central support shaft is a one-joint link (4) composed of a first link (23) and a second link (24) connected together by a rotation shaft. An end portion of the second link is rotatably connected with a front shaft of a subordinate crawler device equipped with crawlers wrapped around rollers. As a result, the crawler robot is composed of a triangular crawler device (2) and the subordinate crawler device (3) connected together by the one-joint link (4). The crawler robot can be operated by rotating and bending the link and by rotating the crawler devices in arbitrary directions.
