ABSTRACT:
A robot hand is implemented by a wrist mechanism coupled with a retaining member for allowing a work to rotate around a first axis, and the wrist mechanism comprises a first bracket member rotational around a second axis and a second bracket member holding the retaining member and rotational with respect to the first bracket member around a third axis, wherein the first to third axes cross at a virtual point within a virtual space occupied by the work so that a distance between the virtual point and a center of the work is decreased, thereby delicately controlling the attitude of the work.
