Multi d. o. f. motions and accurate positioning are required in the micro hand for micro manipulation. For these requirements, various types of parallel mechanisms have been applied to the micro hand mechanisms. Usually, a flexure hinge is applied in a joint mechanism for precise positioning, since it has no backrush as seen in a conventional gear mechanism. It seems rather difficult to fabricate flexure hinges required in the manipulator with more than 3 d. o. f. motions due to their complicated structures. In this paper a new mechanism for the micro finger module is proposed by introducing a unique fabrication method with cutting and folding just a single sheet of metal plate. Thus, a micro hand is assembled easily and quickly with a small cost. A prototype finger module is fabricated, and evaluated with calibration and positioning accuracy tests.
