Abstract:
1. A multi-fingered robot hand comprising: a plurality of finger mechanisms; a first palm portion provided with at least one of the finger mechanisms connected by a first root joint; a second palm portion provided with at least one of the finger mechanisms connected by a second root joint; and a connecting portion connecting the first palm portion and the second palm portion, wherein: the connecting portion has a rotation axis for varying a connection angle of the second palm portion to the first palm portion and permits a variation in the connection angle of the second palm portion to the first palm portion; the first root joint has a rotation axis for bending the corresponding finger mechanism to its palm side; the second root joint has a rotation axis for bending the corresponding finger mechanism to its palm side; the rotation axes are all substantially parallel to each other; the plurality of finger mechanisms includes three finger mechanisms connected in array to the first palm portion; and a middle finger mechanism of the finger mechanisms connected to the first palm portion and one finger mechanism connected to the second palm portion are arranged in such a way that both finger mechanisms move substantially on the same plane when bent.
