Abstract

A robot hand has a plurality of fingers and is provided, at a location at which the robot hand touches an object, with a moving means for touching the object and moving the object. The moving means is provided to the palm side of the robot hand and/or the finger pad side of the robot hand.

Claims

1. A robot hand having a plurality of fingers, wherein the robot hand is provided, at a location at which the robot hand touches an object, with a moving means for touching the object and moving the object.

2. The robot hand according to claim 1, wherein the moving means is provided to the palm side of the robot hand.

3. The robot hand according to claim 1, wherein the moving means is provided to the finger pad side of the robot hand.

4. The robot hand according to claim 1, wherein a plurality of moving means is provided, moving speeds of the object by each moving means mutually differing.

5. The robot hand according to claim 1, wherein a plurality of moving means is provided, moving directions of the object by each moving means mutually differing.

6. The robot hand according to claim 1, wherein a plurality of moving means is provided, each moving means being provided to mutually non-parallel surfaces of the robot hand.

7. The robot hand according to claim 1, wherein the moving means is a belt conveyor.

8. The robot hand according to claim 1, wherein the moving means is provided with elastic members which contain a plurality of pressure chambers, traveling waves being formed on the surface of the elastic members through sequential selective expansion of each pressure chamber, and an object, which touches the surfaces of the elastic members, being moved by the traveling waves on the surface of the elastic members.

9. The robot hand according to claim 1, wherein the moving means is provided with a plurality of polymer actuators and elastic members which are placed on the polymer actuators and latched together, traveling waves being formed on the surface of the elastic members through sequential selective extension of each polymer actuator, and an object, which touches the surfaces of the elastic members, being moved by the traveling waves on the surface of the elastic members.

10. The robot hand according to claim 1, wherein the moving means is a rotatingly driven roller.
