Title:
ROBOT FINGER STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2015/194806
Kind Code:
A1
Abstract:
A robot finger structure comprises: a motor; a crankshaft rotated by the motor; a crank connected to the crankshaft so as to rotate with respect to the crankshaft; a first joint link connected to the crank at a first joint; a second joint link connected to the first joint link at a fourth joint; a first connection link connected to the crank at a second joint so as to transmit rotating power of the crank to the second joint link; and a first rigidity-application device for applying a first rigidity restricting the first joint link from freely rotating with respect to the crank. When the crank rotates without coming into contact with an object, the first joint link and the second joint link rotate together with the crank while maintaining the positions relative to each other. When the first joint link comes into contact with the object such that the rotation of the first joint link is stopped, the crank rotates by overcoming the first rigidity, thereby rotating the second joint link with respect to the first joint link.
