Many types of humanoid robots have been developed, but it is hard to find one with supple spine structure. To act in a proper manner with natural, human-like motions, we believe that humanoid robots should have and use their spines effectively. To find out how to use the spine flexibly and elegantly, we focused on dancing, the art of beautiful movements. Dancing demands you to develop flexible and well coordinated movements of the torso, so we decided to pick up a movement of the sort and realize it by a robot, in order to understand the basics of dancing. This paper describes a way of realizing hula hooping by an exclusive hula-hooping robot as the first step toward dancing humanoids.
