The goal of this research is to investigate different mobility systems which may present advantages over conventional wheel or leg locomotion in microgravity environment. The requirement for the robot is to achieve scientific investigation of the asteroid surface at arbitrary locations with fine positioning capability after large stride movement. It is shown that a robot which has multiple simple legs in a symmetric arrangement can have both large stride and crawling mobility. The paper discusses dynamic behavior of a multi-legged robot in different gravity conditions and shows that the behavior in microgravity environment becomes similar to that in normal gravity by reducing the magnitude of the leg motion and control forces accordingly., 資料番号: AA0047897040}, pages = {227--232}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {Bio-mimetic mechanism for rovers under microgravity surface environment}, year = {2005} }
