Paper Abstract
In this paper precise specifications are given for a microgripper based on a polyarticulated micromechanism. This polysilicon gripper actuated by Scratch Drive Actuators (SDA) has dimensions of 1.2mm.x 1.6mm and a thickness of 0.0045mm. The stroke of its jaws is about 0.275mm each, with a stroke ratio of 5. These specifications can be useful to compare such compliant micromechanisms. In particular, we propose an alternative to the polyarticulated mechanism based on a compliant structure. A new conceptual design method, based on compliant building blocks, is introduced. The proposed method, using a genetic algorithm, quickly leads to several compliant solutions. A compromise between these solutions has performances close to the polyarticulated microgripper (about 20% less).
