Dynamic Regrasping Using a High-speed Multifingered Hand and a High-speed Vision System

Summary

In most previous studies, it has been difficult for a robot hand to regrasp a target quickly because its motion was static or quasi-static with keeping contact state. In order to achieve high-speed regrasping, we propose a new strategy which we call dynamic regrasping. In this strategy, the regrasping task is achieved by throwing a target up and by catching it. In this paper, the regrasping strategy based on visual feedback and the experimental results using a high-speed multifingered robot hand and a high-speed vision system are shown. As an example of a target for dynamic regrasping, we selected a cylinder and we achieved the dynamic regrasping tasks in the experiment.
