Task-based design of cable-driven articulated mechanisms
Proceedings of the 1st Annual ACM Symposium on Computational Fabrication, 2017We present a framework for the automatic design of articulated cable-driven mechanisms performing push andpick-and-place tasks. Provided an initial topology and task specification, our system optimizes the morphology and cable mechanisms such that the resulting mechanism can perform the desired task successfully.

Dynamic analysis of cable-driven parallel mechanisms
Proceedings, 2005 IEEE/ASME International Conference on Advanced Intelligent Mechatronics., 2006A cable-driven parallel mechanism (CDPM) possesses a number of promising advantages over the conventional rigid-link mechanisms, such as simple and light-weight mechanical structure, high-loading capacity, and large workspace. However, the formulations and results obtained for the rigid-link mechanisms cannot be directly applied to CDPMs due to the ...

Workspace Analysis of Multibody Cable-Driven Mechanisms
Journal of Mechanisms and Robotics, 2011A systematic approach is proposed to determine the tensionable workspace of multibody cable-driven mechanisms. The method is also capable of finding analytical descriptions for the boundaries of the tensionable regions for any number of redundant cables used.

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

On the determination of cable characteristics for large dimension cable-driven parallel mechanisms
2010 IEEE International Conference on Robotics and Automation, 2010Generally, the cables of a parallel cable-driven robot are considered to be massless and inextensible. These two characteristics cannot be neglected anymore for large dimension mechanisms in order to obtain good positioning accuracy. A well-known model which describes the profile of a cable under the action of its own weight allows us to take mass and ...

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.

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.
