چکیده

A remotely controlled microgripper has been developed as an end-eeector for a six-degree-of-freedom force-reeecting motion-scaling system. The microgrip-per is small and lightweight, and features relatively high force and stroke compared to other designs. Furthermore , force sensing enables the accurate measurement and control of tool-tissue forces, and the em-ulation of diierent mechanical devices. This paper presents the design of the microgripper and describes some control methods that have been implemented.

Design, Kinematic Optimization, and Evaluation of a Teleoperated System for Middle Ear Microsurgery

Middle ear surgery involves the smallest and the most fragile bones of the human body. Since microsurgical gestures and a submillimetric precision are required in these procedures, the outcome can be potentially improved by robotic assistance. Today, there is no commercially available device in this field. Here, we describe a method to design a teleoperated assistance robotic system dedicated t...

Simulation of a Microgripper with Electrothermal Actuator Using COMSOL Software Based on the Finite Element Method

Micro-electro-mechanical systems (MEMs) are Combination of electrical and mechanical components in Micron dimensions. In recent years, holding, actuating methods and handling of MEMs components such as microgripper, microsensors and etc. have been deeply studied. Microgrippers for handling, positioning and assembling of micro components are very useful so that for clamping need actuation create...

Fault Tolerant Control of a Teleoperated Piezoelectric Microgripper

This paper presents a new architecture of control for micro-teleoperation system using a fault tolerant control (FTC) strategy to compensate for the degradation effects of piezoelectric-based microgipping system. The proposed strategy uses passivity approach for the bilateral controller and robust fault tolerant control (FTC) for the two-fingered microgripper system. First, the bilateral contro...
