Title:
ROBOT HAND
Document Type and Number:
WIPO Patent Application WO/2024/053292
Kind Code:
A1
Abstract:
This robot hand comprises: a root actuator contracting in a cylinder axis direction; a frame member which extends in the cylinder axis direction and to which the root actuator is fixed; and a plurality cylindrical finger actuators which are attached to be spaced apart from each other in the cylinder axis direction of the root actuator so that one-side ends of the finger actuators are fixed to the frame member and the other-side ends serve as free ends, the finger actuators being curved toward one side in the arrow direction in response to an increase in the internal pressure of a cylinder. The frame member, in which a neutral line that maintains the distance between one end fixing section and the other end fixing section in the cylinder axis direction, and the cylinder axis of the root actuator are aligned side by side in an offset state, is curved and deformed according to contraction of the root actuator toward a bending direction where the inside is the opposite side to the neutral line with the cylinder axis of the root actuator therebetween.
