Control Architecture for a Novel Dexterous Hand

نویسنده

  • Chen Wenjie
چکیده

The paper presents a control architecture for grasping task of a novel dexterous hand whose 9 DOFs are actuated by a single-motor-driven actuator through 18 clutches. The architecture highlights the use of microprocessors for real-time control of the multifingered hand. The controller and sensors used in the control system of the hand are also described, which are especially effective to suitability for autonomous and non-numerical or reflex control of grasp.

Design of a novel compact dexterous hand for teleoperation

This paper focuses on the mechanism design of a novel compact dexterous hand of 3 fingers, 9 joints and 7 DOF (degrees of freedom). The technology of single-motor actuation is used and a kind of compact bilateral clutch is designed to reduce the size of actuation and control part of the hand. Different from most dexterous hand designs, no lengthy tendons are needed in this design since the actu...

Developing a Brain- Machine Interface for Dexterous Control of an Upper-limb Neuroprosthesis

A Brain-Machine Interface (BMI) uses electrophysiological measures of brain activity to communicate with external devices, bypassing normal neuromuscular pathways. Earlier research has demonstrated the robust coding capacity of neural activity for gross motor movements such as hand and arm trajectory, and opened up the possibility of a BMI for direct neural control of a prosthetic limb and the ...

Cartesian Impedance Control on Five-Finger Dexterous Robot Hand DLR-HIT II with Flexible Joint

This paper presents an impedance controller for five-finger dexterous robot hand DLR-HIT II, which is derived in Cartesian space. By considering flexibility in finger joints and strong mechanical couplings in differential gear-box, modeling and control of the robot hand are described in this paper. The model-based friction estimation and velocity observer are carried out with an extended Kalman...

Design and Implementation of Dexterous Hand Master Glove to Control the Movements of a Virtual Slave Hand

Dexterous Hand Master (DHM) is one of exoskeletal controlling devices used to measure the positions of an operator’s hand, and utilize these positions to control the motion of a remote manipulator or slave. A simplified kinematics model of a human hand was developed to meet the ability of a proposed DHM glove. Only flexion/extension movements for fingers joints were taken into consideration in ...

Dexterous manipulation is poorer at older ages and is dissociated from decline of hand strength.

BACKGROUND The ability to dynamically control fingertip force vector magnitude and direction is critical for dexterous manipulation. We quantified the dynamic control of fingertip forces to examine how dexterous manipulation declines with age. METHODS The strength-dexterity (SD) test measures fingertip forces during compression of a slender spring prone to instability and buckling. The greate...
