Modelling and control of a bio-inspired microgripper

International Journal of Manufacturing Technology and Management, 2010
A biologically inspired microgripper has been considered with its kinematic model. The dynamic model of the gripper has been developed considering the system with its equivalent lumped inertia, stiffness and damping parameters. The biomimetic gripper developed is conceptually similar to an agonist-antagonistic mechanism. This mechanism is most commonly

Overhung electrostatic microgripper

TRANSDUCERS '91: 1991 International Conference on Solid-State Sensors and Actuators. Digest of Technical Papers, 2002
A monolithic microgripper unit suitable for mounting on a micropositioner has been designed and fabricated by a combination of surface and bulk micromachining. The unit consists of a silicon die (7*5 mm), a 1.5-mm-long support cantilever made from p/sup +/-substrate material and protruding from the die, and a 400- mu m-long polysilicon microgripper ...

Fabrication of an Electrothermally Actuated Electrostatic Microgripper

International Journal of Nonlinear Sciences and Numerical Simulation, 2002
A novel electrostatic microgripper, which can handle micro objects with the electrostatic force, is designed and fabricated. It consists of gripping part with one inner and two outer electrodes, and releasing part with an electrothermal actuator. It grips micro objects using electric field generated between the electrodes, and releases them using the ...

Microgrippers fabricated by the LIGA technique

Sensors and Actuators A: Physical, 1997
A study devoted to the design and fabrication of microgrippers using the LIGA technique is described in this paper. The design method is presented and validated by the use of finite-element analysis. Technological topics are detailed to illustrate the fabrication process.

Untethered microgripper-the dexterous hand at microscale

Biomedical Microdevices, 2019
Untethered microgrippers that can navigate in hard-to-reach and unpredictable environments are significantly important for biomedical applications such as targeted drug delivery, micromanipulation, minimally invasive surgery and in vivo biopsy. Compared with the traditional tethered microgrippers, the wireless microgrippers, due to the exceptional ...

Design and control of a teleoperated microgripper for microsurgery

Proceedings of IEEE International Conference on Robotics and Automation, 2002
A remotely controlled microgripper has been developed as an end-effector for a six-degree-of-freedom force-reflecting motion-scaling system. The microgripper is small and lightweight, and features relatively high force and stroke compared to other designs.

Silicon-processed overhanging microgripper

Journal of Microelectromechanical Systems, 1992
A silicon-processed microgripper, suitable for mounting on a micropositioner, has been designed and fabricated by combining surface and bulk micromachining. The microgripper consists of a silicon die (7 mm*5 mm), a 1.5 mm long support cantilever, made from boron-doped silicon substrate material (protruding from the die), and a 400 mu m long polysilicon

Microgrippers realized by LIGA techniques

Proceedings 1995 INRIA/IEEE Symposium on Emerging Technologies and Factory Automation. ETFA'95, 2002
Development of new methods and techniques derived from microelectronics technology and devoted to the fabrication of small mechanical objects has yield the realization of micromechanical devices for actuating or sensing operations. However, among the devices built using these techniques, microgrippers have not received a great deal of interest. Most of

Development of Haptic Microgripper for Microassembly Operation

2010
In recent times, dimensions of consumer products have decreased, with components sizes ranging down to micrometers/nanometers. In case of microproducts that are produced in low-medium quantities with many variants, the automation of their assembly process may not be economically profitable.

Optical Characterization with the Waveguide Microgripper

2009
We have developed a novel waveguide microgripper capable of physically grasping a microobject while simultaneously delivering and collecting light through its waveguide arms. This capability allows extensive optical characterization of the structure being held such as transmission, reflection or fluorescence.
