A Cable-Driven Parallel Mechanism for the Interaction with Hemispherical Surfaces
2012In this paper, a device based upon a specific cable-driven parallel mechanism to interact with hemispherical surfaces is proposed and investigated. This device could be of use in, for example, the automated cleaning of glass domes. Because the cables move on the hemispherical surface, they are curved.

An asymmetric cable-driven mechanism for force control of exoskeleton systems
Mechatronics, 2016In this paper, an asymmetric cable-driven mechanism is proposed for accurate force control of exoskeleton systems with a compact structure. Inspired by the fact that the required forces in human motions are not symmetric in many cases, a spring-actuator type cable-drive mechanism is adopted, which enables a compact cable routing structure. The joint is

A Cable-Driven Grasping Mechanism With Lock/Unlock Constraints
Volume 6A: 37th Mechanisms and Robotics Conference, 2013The application of manipulators is becoming more and more popular in object handling especially when it is desired to have access to remote areas in destructive or hazardous taskspaces. For this purpose, a hand-like mechanism must be designed to be used as an end-effector, which can grasp objects.

Design and Analysis of a Cable-Driven Deployable Cylindrical Mechanism
Volume 5B: 42nd Mechanisms and Robotics Conference, 2018This paper presents the design of a deployable cylindrical mechanism which is driven by cable. The deployable mechanism can be deployed to approximate a cylindrical surface and be folded into a compact bundle. Construction of the cylindrical surfaces with Bennett linkages is introduced. Geometric shape of the connecting bars and structure of the joints

A Hybrid Self-Stressed Cable-Driven Mechanism
Volume 2: 32nd Mechanisms and Robotics Conference, Parts A and B, 2008A new hybrid cable-driven manipulator is introduced. The manipulator is composed of a Cartesian mechanism to provide three translational degrees of freedom and a cable system to drive the mechanism. The end-effector is driven by three rotational motors through the cables.

Wrench Capability Analysis of Cable-Driven Parallel Mechanisms
Volume 6: 35th Mechanisms and Robotics Conference, Parts A and B, 2011The maximum wrench capabilities of the cable-driven parallel mechanisms are investigated in this paper. Focusing on accuracy and efficiency, two methods, an optimization-based method and a hybrid method based on optimization and geometry, are presented for determining the wrench capability of the cable-driven parallel mechanisms.

Cable-Driven Parallel Mechanisms: Application to a Locomotion Interface
Volume 8: 31st Mechanisms and Robotics Conference, Parts A and B, 2007Over the last decade, cable-driven parallel mechanisms have been used for several purposes. In this paper, a novel application is proposed, namely, using two 6-DOF cable-driven parallel mechanisms sharing a common workspace to obtain the mechanical base for the design of a locomotion interface.

A PLANAR CLOSED-LOOP CABLE-DRIVEN PARALLEL MECHANISM
Transactions of the Canadian Society for Mechanical Engineering, 2009A novel architecture of planar closed-loop cable-driven parallel mechanism is introduced in this paper. In this architecture, instead of being wound on spools, the cables form closed loops attached to the end-effector and whose motion is controlled by sliders.

Workspace Analysis of a Three DOF Cable-Driven Mechanism
Journal of Mechanisms and Robotics, 2009A cable-driven mechanism based on the idea of BetaBot (2005, “A New Cable-Based Parallel Robot With Three Degrees of Freedom,” Multibody Syst. Dyn., 13, pp. 371–383) is analyzed and geometrical description of its workspace boundary is found. In this mechanism, the cable arrangement eliminates the rotational motions leaving the moving platform with ...

Dynamic Analysis on Flexible Cable-Driven Parallel Mechanism
Advanced Materials Research, 2014The interference between cables and surface of acutator limits the movement in the cable-driven parallel mechanism. The mechanism with fixed hinge can’t absolutely avoid the interference point of the track when using linear programming method. One new method, named as distant interference, was proposed to pick out all the interferential points of the ...
