“…The dynamic behavior is quite good since the authors point out an amplitude of the finger motions of 500 m at a frequency of 150 Hz. hydraulic grippers: [24] presents a prototype using an hydraulic principle with mercury as the fluid. The displacement of the piston is generated in this case by a rise in temperature of the fluid in a deformable chamber.…”

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 m 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.

In this paper novel tools for micromanipulation are presented. The devices have been purposely designed for integration in small mobile micro-robots, aimed at performing co-operative precision manipulation and assembly tasks. Concerning the actuation, multilayer piezoceramic components were developed and employed. The selected fabrication techniques for the grippers are shape deposition manufacturing of polymer and electro-discharge machining of stainless steel, and different alternatives have been investigated in order to select the optimal design. Several prototypes have been fabricated and preliminary experimental tests have been performed, both regarding the characterization and the grasping capabilities.

“…It was found from the diverse micrograsping models in literature that researchers have predominantly emphasized on three major components during model development namely novel microfabrication techniques [9,10], new actuation methodologies [11][12][13] and manipulation of different materials [14][15][16] of smart structures have advanced the grasping technologies and enable compact, highly compliant, and monolithic mechanism to be realized. The fabrication techniques such as Electro Discharge Machining (EDM), LIGA, surface, bulk and laser micromachining, and photo lithography have paved a decisive breakthrough to the persisting constraints in micrograsping methodology particularly associated with the object-gripper compatibility, surface to surface interaction between the object and the gripper's jaws and nonlinearity during operation [9,10,17,18].…”
