Document Type and Number:
WIPO Patent Application WO/2010/053245
Kind Code:
A1
Abstract:
The present invention relates to a robot hand with a connection part that undergoes stretching deformation according to object shape and a method for controlling a robot hand; the key technical point pertains to a robot hand with a connection part that undergoes stretching deformation according to object shape, comprising: a variable connection device (100) that provides a contact face that enables pressing and contacting a moving target (10) and has a structure wherein a connection part (100a) in contact with said moving target (10) enables stretching deformation; a connection length controller (200) that interfaces with a drive part such as a motor (201) or pump to stretch and deform the connection part (100a) of said variable connection device so that the connection part (100a) of said variable connection device undergoes conversion between a closed-loop state wherein it is continuous with the surface of said moving target (10) or divided into a plurality of sections to be pressed and contacted, and an open-loop state wherein it detaches from said moving target (10); and a shape retention device that retains the shape of said variable connection device (100)consistently in a closed-loop state wherein said variable connection device (100) is pressed and contacted with said moving target (10) at a set pressure, and specifically to a robot hand with a connection part that undergoes stretching deformation according to object shape and a method for controlling the robot hand, having a structure that enables the reliable and stable performance of pick and move operations including enveloping, hooking, and sweeping, among the various operations performed by a human hand.
