Self-Biased-SMA Drive PU Microgripper with Force Sensing in Visual Servo
International Journal of Advanced Robotic Systems, 2013 An innovative design of a polyurethane microgripper system with force sensor is developed for the measurement of gripping force in vision-based control. A microgripper mechanism integrated with a force sensing arm is fabricated by an excimer laser.

Overview of Microgrippers and Design of a Micromanipulation Station Based on a MMOC Microgripper [PDF]
2005 International Symposium on Computational Intelligence in Robotics and Automation, 2005 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 50mum to approximately 2 mm and a maximum forces varying from ...

Universal Soft Robotic Microgripper [PDF]
Small, 2018 AbstractHere, a soft robotic microgripper is presented that consists of a smart actuated microgel connected to a spatially photopatterned multifunctional base. When pressed onto a target object, the microgel component conforms to its shape, thus providing a simple and adaptive solution for versatile micromanipulation. Without the need for active visual

Design of large-displacement asymmetric piezoelectric microgripper based on flexible mechanisms
Nanotechnology and Precision Engineering, 2019 The output displacement of the traditional symmetrical microgripper is large, but its micro-components or parts are easily damaged due to the uneven force exerted on the left and right jaws of the gripper.

A Submerged Freeze Microgripper for Micromanipulations [PDF]
Proceedings 2007 IEEE International Conference on Robotics and Automation, 2007 Efficient, reliable and flexible handling is still very challenging in micromanipulation and micro-assembly. In this paper, we propose an original thermally actuated gripper based on the use of ice to manipulate submerged artificial micro-objects sized under 100 mum.

Hybrid Optothermal-Magnetic Mobile Microgripper for in-liquid Micromanipulation
, 2022 In this paper, we propose a mobile microgripper actuated using laser optothermal and magnetic actuation in liquid environments. This hybrid actuation scheme allows the full decoupling between the in-plane positioning of the mobile microgripper and the ...

Tetherless thermobiochemically actuated microgrippers [PDF]
Proceedings of the National Academy of Sciences, 2009 We demonstrate mass-producible, tetherless microgrippers that can be remotely triggered by temperature and chemicals under biologically relevant conditions. The microgrippers use a self-contained actuation response, obviating the need for external tethers in operation. The grippers can be actuated en masse, even while spatially separated.

Toward an Electroactive Polymer-Based Soft Microgripper [PDF]
IEEE Access, 2021 Grasping and manipulating objects on a microscale hold great promise, especially using mechanical structures made from soft materials that enable, for example, safe operations during microsurgery. Soft robots should be preferred to manipulate micro-objects, but their adoption requires, inter alia, soft transducers that can operate either in air or in ...
