Untethered Microgrippers for Precision Medicine
Small, 2023AbstractMicrogrippers, a branch of micro/nanorobots, refer to motile miniaturized machines that are of a size in the range of several to hundreds of micrometers. Compared with tethered grippers or other microscopic diagnostic and surgical equipment, untethered microgrippers play an indispensable role in biomedical applications because of their ...

Development of microgripper system
2011 XXIII International Symposium on Information, Communication and Automation Technologies, 2011The paper presents the experimental development of micro/nano robotic cell for assembling the micro objects. Three techniques for gripping of micro objects with micro/nano robot are presented. The first one uses a two finger gripper and is suitable for objects which are greater than 100 μm.

Optimal Design of Microgripper
First International Conference on Innovative Computing, Information and Control - Volume I (ICICIC'06), 2006This paper presents a microgripper design and utilizes the topology optimum method to obtain larger output force and displacement. The goal of this study is to obtain the sharpest topology layout by simulation and computing. The difference between compliant mechanisms and traditional mechanisms is that compliant mechanisms have flexible pieces to ...

Sensors and Actuators A: Physical, 2001
A microgripper system is presented, which consists of a monolithic shape memory alloy (SMA) device of 2 × 5.8 × 0.23 mm3 size and an integrated optical position sensor. By use of an integrated gear actuator, the motion of gripping jaws is transmitted into a linear motion of an integrated optical slit, which is detected by change of optical transmission.

Performance Evaluation Methods for Microgrippers
Volume 4: 19th Design for Manufacturing and the Life Cycle Conference; 8th International Conference on Micro- and Nanosystems, 2014In precise manipulation and assembly of components with sub-millimetric dimensions, the role of the gripping tools is fundamental. In the literature, many different types of the so-called microgrippers have been presented, based on different working principles, to cope with the issues related to the gripping, the handling and the release of different ...

4-axis electromagnetic microgripper
Proceedings 1999 IEEE International Conference on Robotics and Automation (Cat. No.99CH36288C), 2003This paper describes a novel 4-axis microgripping system consisting of two fingers, each driven by a 2-axis moving coil actuator taken from a CD-lens assembly. These electromagnetic actuators are small, very linear, virtually frictionless and low cost. We measured the electrical actuator parameters and characterized the actuator performance in terms of

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.

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.
