    Abstract

    This paper discusses an object capturing task with a two arm flexible manipulator. To realize a stable capture with no slips at the end-effectors on the object surface, the internal force being developed in the object needs to rise quickly. For this purpose, the relationship between the end effectors' approach velocities to the object and the internal force during the capture is analyzed with a simple mass-damper-spring model for the two arm manipulator and the object system. Furthermore, a method for changing the control modes is proposed considering the resultant mechanical compliances at the tips of the arms so that the rise time of the internal force is reduced. The effectiveness of this method is verified with experiments.
