Title:
ROBOT HAND
Document Type and Number:
WIPO Patent Application WO/2020/115889
Kind Code:
A1
Abstract:
When grasping an object, an adjustment control unit (280A) performs control for forcibly discharging air from bellows of finger parts (140Aj) (j = 1, …, 4). With this control, the bellows contract and generate a force in a rotating direction that brings first and second joints into an extended state, and a finger 140A is brought into an extended state. When the first and second joints are brought into the extended state, a robot hand (100A) moves to be located near the object by a support device. Subsequently, the adjustment control unit (280A) performs control for forcibly supplying air to the bellows. With this control, the bellows expand and generate a force in a rotating direction that brings the first and second joints into a bent state, a finger base portion rotates about a shaft member as a rotation axis, relative to a first link portion, and a fingertip portion rotates about a shaft member as a rotation axis, relative to the finger base portion. Thus, the bent finger parts (140Aj) grasp the object.
