Robot hand, robot device and method of manufacturing robot hand

Abstract

A robot hand includes a finger unit that is in contact with an object. The finger unit includes: a first member in which a tip portion and a base portion connected to the tip portion are formed as a single member; and a second member that covers a surface of the first member.

What is claimed is: 
     
         1 . A robot hand comprising:
 a first member that has a bending portion, and has a first surface in a direction in which the bending portion bends, and   a second member that is adapted to contact an object, the second member being provided to the first surface and being more elastically deformable than the first member.   
     
     
         2 . The robot hand according to  claim 1 , comprising:
 a third member that is rotatably provided to the bending portion.   
     
     
         3 . The robotic hand according to  claim 2 , comprising:
 an elastic member that is provided between the first member and the third member.   
     
     
         4 . The robotic hand according to  claim 1 , comprising:
 a chamber that is located between the first member and the second member.   
     
     
         5 . A robot device comprising:
 a robot body; and   the robot hand according to  claim 1  operatively associated with the robot body.   
     
     
         6 . A robot device comprising:
 a robot body; and   the robot hand according to  claim 2  operatively associated with the robot body.   
     
     
         7 . A robot device comprising:
 a robot body; and   the robot hand according to  claim 3  operatively associated with the robot body.   
     
     
         8 . A robot device comprising:
 a robot body; and   the robot hand according to  claim 4  operatively associated with the robot body.   
     
     
         9 . A robot device comprising:
 a first arm that includes a first robot hand, and   a second arm that includes a second robot hand, wherein the first and second robot hands are configured to hold an object,   wherein each of the first and second robot hands includes:
 a first member that has a bending portion, and has a first surface in a direction in which the bending portion bends, and 
 a second member that is adapted to contact an object, the second member being provided to the first surface and being more elastically deformable than the first member.
