Abstract: A robot hand with a connection part that undergoes stretching deformation according to object shape. The robot hand includes a variable connection device that provides a contact face that enables pressing and contacting a moving target and has a connection part in contact with the moving target enables stretching deformation; a connection length controller that interfaces with a drive part to stretch and deform the connection part so that the connection part undergoes conversion between a closed-loop state wherein it is continuous with the surface of the moving target or divided into a plurality of sections to be pressed and contacted, and an open-loop state wherein it detaches from the moving target; and a shape retention device that retains the shape of the variable connection device consistently in a closed-loop state wherein the variable connection device is pressed and contacted with the moving target at a set pressure.

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 ope
