Ultra-high-performance robot hand that completely imitates the movements of human fingers, the world of the Ghost Inner shells reality

Conventional robot hands are structurally difficult to move in the same way as human beings, but by scanning the skeleton of the human hand with a laser and outputting the data with a 3D printer, complex movements are possible The hinge and gimbal which hit joints and muscles to be done are realized, and a high-performance robot hand which imitates the movement of human hand precisely with five fingers has been realized.

A demonstration in which a high performance robot hand actually performs various actions can be seen from the following movie.

Washington University's development of robot hands far beyond conventional precisionZhe XuWith doctorEmanuel TodorovDoctor. Dr. Xu's hands are equipped with various codes and equipment, and the robot hand on the right side is linked to the movement of the doctor's hand.


Hold in the hand and make a fist ...


I am demonstrating how to move the forefinger and move one finger. Although there is a slight delay in response, the robot hand shows complicated movement almost in real time. From the wrist down to 10Dynamixel ServoAnd it imitates the movement of the muscles of the human arm.


Demonstration that the place changes and grasps various objects with different shapes starts. The first one was a small ball, handed the ball to the robot hand with the right hand and grasped with the left hand, the robot hand gripped the ball tightly. There are two or three robot hands instead of five fingers, but the robot hand at the University of Washington shows that they hold a ball by combining multiple fingers like a human being.


This is a thin CD as well.


There is no problem with the precise movement of holding the tape with your thumb and index finger.


It is also possible to grab a wallet with the full use of five fingers.


You can take a pen with a person holding it like a human being, if you have paper, you can even write letters.


We tried to pinpoint only one small and thin key, and demonstrated it without difficulty.


This is the end of the movie, but it seems that you can also grasp and grab a number of tools such as coins, plates, bills, towels, and coffee cups.


According to Dr. Xu, it seems that it is difficult to reproduce the movement of the thumb with particularly complex joints in the structure of the conventional robot hand. In order to reproduce motion where the axis of the joint is not completely fixed, output the human bones with a 3D printer, attach the equivalent of a joint with the same range of motion as a human, then take it to the extensor and flexor tendon By using alternative strings of strength and rubber sheet as soft tissue, we have successfully imitated robotically the movement of the living body of human hands as much as possible.
