A Partially Decoupled Hybrid Manipulator with Separated Positions and Poses
Hybrid manipulator has high bearing capacity of parallel manipulator and large operating space of series manipulator,so it has broad engineering application prospect. Taking the RPS parallel mechanism with decoupled characteristic as a module,a partially

The kinematics of the redundant $N-1$ wire driven parallel robot [PDF]
We address the kinematics of the redundant $N-1$ wire-driven parallel robot, i.e. a robot with $N > 3$ wires connected at the same point on the platform. The redundancy allows one to increase the workspace size.

Stiffness Model of a 3-DOF Parallel Manipulator with Two Additional Legs
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
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 ...

Comparison of actuation schemes for wire-driven parallel robots [PDF]
There are two main systems that can be used to coil and uncoil the wires of a wire-driven parallel robots: a rotary motor that turns a drum on which the wire is coiled or a linear motor with a pulley system.
