This study deals with a multi-legged planetary rover with a spherically isotropic leg arrangement. This robot is a reliable system for the exploration on rough terrains, because the rover can continue walking even after overturning. Moreover, this rover can exhibit a rotational motion by utilizing its isotropic shape in addition to quadruped walking motion. This paper discusses two rotational motions; a quasi-static rotational motion and a dynamic rotational motion. This paper investigates reasonable attitudes for the quasi-static rotational motion from the view point of the energy consumption required for traveling. For the dynamic rotational motion, adequate attitudes to resist the shock for kicking and touchdown are discussed.
