Abstract
To realize hyper dynamic manipulations such as jumping by a smart structure, authors have proposed the utilization of dynamically-coupled driving and joint stop mechanisms before. The purpose of this work is to apply the idea to humanoids to realize hyper dynamic manipulations. This paper investigates the possibility of jumping by a small commercial humanoid with newly introduced joint stop mechanisms. The motion planning for jumping has been performed with considering the capability of actuators in the humanoid and the possibility for jumping has been examined by simulation.
