Dynamic active catching using a high-speed multifingered hand and a high-speed vision system

Abstract

A new robotic hand system with high-speed finger motion of 180 [deg] per 0.1 [s] has been developed. With high-speed visual feedback at a rate of 1 [kHz], various dynamic manipulations are achieved. As examples of dynamic manipulation we describe the dynamic active catching tasks for a falling ball and a falling cylinder using a high-speed multifingered hand. We achieved these difficult tasks by utilizing high-speed motion and impact forces actively. Experimental results using active catching strategy based on visual feedback are shown.
