Document Type and Number:
Japanese Patent JP2014205207
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a robot hand securing a shape and strength necessary for the hook of a robot hand, and also avoiding such a defect that the hook involuntarily gets stuck with an object so as to be applicable to detailed-oriented tasks.SOLUTION: A hook 16 set on a finger 14 comprises a bag 18 and particles 20 sealed up in the inside of the bag 18. The hook 16 flexibly changes its appearance configuration within a range where the deformation of the bag 18 is allowed because the positions of the particles 20 are changed inside the bag 18. The pressure inside the bag 18 is reduced by pressure adjustment means 22 and thereby the hardness of the hook 16 is increased. The hardness of the hook 16 is adjusted and increased when using the hook 16, the hook 16 is hung on an object to be moved, and is moved. When the hook 16 is not used, the hardness of the hook 16 is reduced, and the hook 16 is flexibly deformed even when getting in touch with the object, and is prevented from getting stuck with the object.
