Industrial Robot: An International Journal, 2003
Describes the benefits of using electroadhesion when handling very delicate, polished and/or coated optical and electro‐optical microcomponents. Electroadhesion is a technique already familiar to those working in the semiconductor industry and is eminently suitable for the handling of microcomponents in air, gas or vacuum.

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 × 1.6mm and a thickness of 4.5µm . The stroke of its jaws is about 275µm each, with a stroke ratio of 5.

Design of topologically optimal microgripper
2008 IEEE International Conference on Systems, Man and Cybernetics, 2008This paper presents a topological-optimization method which applies the theory of ground structure parameterization to design and analyzes a microgripper device. The study defines the compliant design domain as 2000 mum times 2000 mum with a 200 mum thickness, and discusses the effect of different optimization parameters.

Micropeg manipulation with a compliant microgripper
2003 IEEE International Conference on Robotics and Automation (Cat. No.03CH37422), 2004This paper presents analytical, simulation and experimental results from a study of compliant insertion tasks in microassembly. Gripper compliance is desirable to compensate for positional errors and to prevent the breakage of a gripper during assembly tasks.

Design Tradeoffs for Electrothermal Microgrippers
Proceedings 2007 IEEE International Conference on Robotics and Automation, 2007Microgrippers based on electrothermal actuation were designed and fabricated using the deep reactive ion etching (DRIE) process with 100mum thick silicon on insulator (SOI) wafer. The design requirements are restricted to basic manipulation tasks such as pick and place, and nonprehensile manipulation.

SPIE Proceedings, 2001
A large number of microgrippers has been developed in industry and academia. Although the importance of hybrid integration techniques and hence the demand for assembly tools grows continuously a large part of these developments has not yet been used in industrial production.

Electrostatically driven microgripper
Microelectronic Engineering, 2002Abstract In this work we report on microactuators and microgrippers fabricated from SOI (silicon-on-insulator) wafers by a surface and bulk micromachining fabrication technology. The main advantages of this technology are: (a) large thickness of the devices (10–40 μm) resulting in devices which are stable against disturbing forces perpendicular (z ...

Integrated fabrication of a microgripper
Journal of Shanghai University (English Edition), 1999Successful implementation of simple mechanism on silicon chip is a prerequisite for monolithic microrobotic systems. This paper describes the integrated fabrication of polycrystalline silicon microgripper. Link, fixed and active joint, and sliding flange structures with dimensions of micrometers have been fabricated on the substrate of monocrystalline ...

An electrowetting based microgripper
2008 51st Midwest Symposium on Circuits and Systems, 2008In this paper, we present a novel capillary microgripper that can pick up and release micro objects simply by electrowetting. Electrowetting on dielectric (EWOD), a phenomenon which uses electrical potential to manipulate the surface tension of a liquid droplet is utilized to control the lifting forces.

An automatic vacuum microgripper
2010 8th World Congress on Intelligent Control and Automation, 2010Picking and releasing the micro parts is one of the most important tasks for the microassembly robot. Downsizing the grippers used in the macro world is not suitable to fulfill the manipulation in the micro world because of the different scaling of gravity and adhesion.
