Cartesian Control of a Cable-Driven Haptic Mechanism

open access: yes, 2010
Haptic devices operated through a communication network require a trade-off between the stability of the interaction and the quality of the haptic display. A haptic device must be designed to provide the best haptic display in order to reproduce the tactile sensation of virtual objects, rigid or soft, while ensuring a stable operation to guarantee user

Design of a Cable-Driven Four-Bar Mechanism for Arm Rehabilitation [PDF]

open access: yes, 2016
This paper presents the design of an assistive mechanism to be used for the rehabilitation of human arm. First the motions of two types of rehabilitation exercises are described. The motions are planar motions, so a planar four bar mechanism is designed. The synthesis problem is formulated as a three-position synthesis problem.

Cable-Driven Mechanism Models for Sensitive and Actuated Minimally Invasive Robotic Instruments

open access: yesApplied Sciences
Cable-driven mechanism models are, usually, included in actuated systems; however, recently, their use for sensitive systems has been explored. In this paper, two cable-driven multi-body mechanism models are compared, underlining advantages and ...

A two-axis cable-driven ankle-foot mechanism [PDF]

open access: yesRobotics and Biomimetics, 2014
Abstract This paper describes a novel cable-driven ankle-foot mechanism with two controllable degrees of freedom (DOF) in dorsiflexion-plantarflexion (DP) and inversion-eversion (IE). The presented mechanism is a proof of concept to demonstrate feasibility.

Calculation of the cable-platform collision-free total orientation workspace of cable-driven parallel robots

open access: yes, 2022
S.137-148The large workspace of cable-driven parallel robots is one of their main benefits over conventional parallel robots with rigid links. Therefore, it is crucial to measure its size and analyze its constraints.

Single Actuator with Versatile Controllability of 2-DOF Assistance for Exosuits via a Novel Moving-Gear Mechanism

open access: yesActuators, 2022
Decreasing the system weight while maintaining the assistance performance can help reduce the metabolic penalty in exosuits. Various researchers have proposed a bi-directional cable-driven actuator that can provide two degrees of freedom (2-DOF ...
