Abstract

We address in this paper the problem of planning motion of free floating robot. Due to the conservation of angular and linear momentum during the in-air motion, the problem is two-fold: one needs to design, in addition to the in-air motion, the initial impulse that imparts the robot with the appropriate momentum to perform a desired motion. We propose in this paper a new method to address this problem. The method is a homotopy method which deforms an arbitrary path connecting the desired initial and final states to a feasible trajectory between these states, that is a trajectory that meets the system's dynamics and constraints. From this trajectory, the method extracts both the controls and initial momentum needed to perform the motion. We illustrate the method by designing somersault motions for a diver robot.
