Card Throwing and Shooting by a High-speed Multifingered Hand and a Vision System

Summary

We successfully demonstrated dexterous manipulation of sheet-like elastic objects, namely, playing cards, using a high-speed robot system. In particular, our goal was to achieve card throwing and card shooting of a target object by a high-speed multifingered robot hand and a visual feedback based on a vision system. We discuss card grasping in the initial state by analyzing a motion of a human subject for achieving card throwing, and we propose a strategy for card throwing and card shooting. We also explore a grasping position of a card and a release timing to perform the card throwing toward a desired direction. Finally, we show experimental results of card throwing and card shooting of target objects, such as a static cup, a static pen and a moving cup, without/with visual feedback.
