Abstract
Provision of a 3-DOF micro manipulator easy to operate and capable of executing accurate positioning, wherein the link mechanisms of the micro manipulator whose main operation is parallel 3-DOF operation are implemented by cutting, folding, and moding a sheet of metal plate. Base and end effector are connected by three link mechanisms. The three link mechanisms are manufactured by cutting and folding a flexible plate material, and are equipped with plate-like arm portions each having a spread in the axially peripheral direction of the end effector, with hinge portions that are formed longitudinally across each arm portion in order to function as revolving joints R, and with a hinge portion also formed at the middle position of the arm portion in order to function as revolving joints R. Also, a parallelogrammatic link is formed between one longitudinal end of the arm portion and the middle portion thereof in order to function as a prismatic joint pair P.
