A novel approach for 2-degrees of freedom redundant parallel manipulator dynamics
Advances in Mechanical Engineering, 2017 A novel Udwadia–Kalaba approach for redundant parallel manipulator dynamics is presented in this article. This methodology is explicit and simple which is suitable for systems with holonomic or non-holonomic constraints.

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 ...

Performance analysis for a 2 (3HSS+S) parallel manipulator with double moving platforms
International Journal of Advanced Robotic Systems, 2016 The working efficiency of a parallel manipulator with double moving platforms is better than a parallel manipulator with a single moving platform. In this study, a 2 (3HSS+S) parallel manipulator is presented, and the topology model of the parallel ...
