Tool Manipulation by a Multifingered Hand Using a High-speed Vision


In order to achieve skillful handling, it is necessary that a multifingered hand has a capability to manipulate tools. One important problem of tool handling with a multifingered hand is that the relative positions among a robot hand, a tool and a handled object change during the handling. For this reason, it is necessary to measure the relative positions in real time, and to control a hand so as to cancel the changes by passive joint arise from frictional force between hand and tools. In our research, we have resolved this problem by using a high speed visual servoing. As an example, a tweezers is handled by a multifingered hand.
