Dynamic Analysis on Flexible Cable-Driven Parallel Mechanism

Advanced Materials Research, 2014
The 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 ...

Workspace Analysis of a Three DOF Cable-Driven Mechanism

Journal of Mechanisms and Robotics, 2009
A 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 ...

Tension analysis of cable-driven parallel mechanisms

2005 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2005
A 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 ...

Impedance Control of Cable-Driven Mechanisms

Volume 2: 32nd Mechanisms and Robotics Conference, Parts A and B, 2008
In this work, an impedance control method is developed and applied to two cable-driven mechanisms. The first one is a classical problem of driving a rigid body in 3-D space by seven cables. Our approach is based on the impedance control of rigid link manipulators which is then extended to include the specific considerations of the cable-driven ...

Task-based design of cable-driven articulated mechanisms

Proceedings of the 1st Annual ACM Symposium on Computational Fabrication, 2017
We 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.

Wrench-Feasible Workspace of Parallel Cable-Driven Mechanisms

Proceedings 2007 IEEE International Conference on Robotics and Automation, 2007
The wrench-feasible workspace (WFW) of a parallel cable-driven mechanism is the set of poses of its mobile platform for which the cables can balance any wrench in a specifed set of wrenches, such that the tension in each cable remains within a prescribed range. The WFW is fundamental since it takes into account both the requirement of nonnegative cable

Workspace Analysis of Multibody Cable-Driven Mechanisms

Journal of Mechanisms and Robotics, 2011
A 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.
