ABSTRACT:
A microgripper device includes a microactuator member and a microgripper member. The microactuator member includes an actuating portion adapted to output a driving force to the microgripper member. The microgripper member includes a main flame, an engaging portion, a pair of lateral shifting portions and a gripping portion. The main frame of the microgripper member mounts the microactuator member therein, and the engaging portion of the microgripper member connects to the actuating portion of the microactuating member. Each of the lateral shifting portions includes three connection portions linking the main frame, the engaging portion and the gripping respectively. The gripping portion of the microgripper member includes a pair of resilient arms and a pair of pivot portions. Each of the pivot portions connects to a first end of the corresponding resilient arm so that the second ends of the resilient arms are able to generate a gripping movement.
