All-directional Walking of a Quadruped Robot based on Crawl and Rotation Gaits

Abstract

In this paper, we propose a successive gait-transition method for a quadruped robot to realize all-directional static walking. The gait-transition is successively performed among the crawl gaits and the rotation gaits while the foots hold in common positions before and after gait-transition. The transition time of the gaits is reduced through carefully designing the foot position of the crawl gait and the rotation gait while limiting the foot in a rectangular reachable motion ranges. Experimental test was executed to show the validity and the limitation of the proposed gait-transition method.
