Overview of Microgrippers and Design of a Micromanipulation Station Based on a MMOC Microgripper

Abstract

This paper deals with an overview of recent microgrippers. As the end-effectors of micromanipulation systems, microgrippers are crucial point of such systems for their efficiency and their reliability. The performances of current microgrippers are presented and offer a stroke extending from 50 μm to approximately 2 mm and a maximum forces varying from 0,1 mN to 600 mN. Then, micromanipulation system based on a piezoelectric microgripper and a SCARA robot is presented.
