On the stability properties of hexapod tripod gait

Abstract

Hexapod tripod gaits for straight-line motion and crab walking are derived. Mathematical relations that express the stability margin, the stride length, and the duty factor are formulated for straight-line motion and for crab walking, respectively. The derived results provide tripod gaits of the hexapond for walking with a prescribed stability margin either over perfect terrain or constant slope terrain.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
