Wrench-Closure Condition of Cable-Driven Parallel Manipulators
Applied Sciences, 2021 Cable-driven parallel manipulators (CDPM) have parallel structures that consist of moving platforms connected to the fixed platform through many flexible cables. The moving platform is driven by many winches, and because of the unidirectional property of

Working Modes and Aspects in Fully-Parallel Manipulator [PDF]
, 1998 International audienceThe aim of this paper is to characterize the notion of aspect in the workspace and in the joint space for parallel manipulators. In opposite to the serial manipulators, the parallel manipulators can admit not only multiple inverse ...

Particularities of fully-parallel manipulators in 6-DOFs robots design: a review of critical aspects
MATEC Web of Conferences, 2017 A whole range of industrial applications requires the presence of parallel mechanisms with six degrees of freedom (6-DOF) which have been developed in the last fifteen years, and one of the reasons why they still are a current topic is that present-day ...

Stiffness Model of a 3-DOF Parallel Manipulator with Two Additional Legs
International Journal of Advanced Robotic Systems, 2014 This paper investigates the stiffness modelling of a 3-DOF parallel manipulator with two additional legs. The stiffness model in six directions of the 3-DOF parallel manipulator with two additional legs is derived by performing condensation of DOFs for ...
