Sensitivity comparison of planar parallel manipulators [PDF]
Mechanism and Machine Theory, 2010 This paper deals with the sensitivity comparison of three Degree-of-Freedom planar parallel manipulators. First, a methodology is described to obtain the sensitivity coefficients of the pose of the moving platform of the manipulators to variations in their geometric parameters and actuated variables.

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 ...

Internal redundancy: an approach to improve the dynamic parameters around sharp corners [PDF]
Mechanical Sciences, 2013 In recent years, redundancy in parallel manipulators has been studied broadly due to its capability of overcoming some of the drawbacks of parallel manipulators including small workspaces and singular configurations. Internal redundancy, first introduced

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

Singular Curves in the Joint Space and Cusp Points of 3-RPR parallel manipulators [PDF]
, 2006 International audienceThis paper investigates the singular curves in the joint space of a family of planar parallel manipulators. It focuses on special points, referred to as cusp points, which may appear on these curves.

Stiffness modeling of non-perfect parallel manipulators [PDF]
, 2012 The paper focuses on the stiffness modeling of parallel manipulators composed of non-perfect serial chains, whose geometrical parameters differ from the nominal ones.

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 ...
