This paper presents a novel constant force mechanism based on a 11- revolute joints spatial linkage using simple pin joints and two regular springs. Passive linear sliders with ball bearings are not suitable for certain applications such as in medical environment or for miniat ...
A complete stiffness analysis of a parallel manipulator considers the structural compliance of all elements, both in designed degrees-of-freedom (DoFs) and constrained DoFs, and also includes the effect of preloading. This paper presents the experimental validation of a Jacobian-

Parallel robots with configurable platforms
Fundamental aspects of a new class of robotic architectures
The Cartesian stiffness analysis of mechanisms and robotic manipulators is often performed using Jacobian-based stiffness analysis methods. In general it is necessary to consider the effect of loading, which introduces a Jacobian-derivative term. However, early examples of stiffn

Conventional parallel robots are formed by several independent serial chains, connecting in-parallel a single rigid platform, or end-effector, to the base. The novel concept behind a parallel robot with configurable platform is that the rigid end-effector is replaced by a closed-

This paper explores the fundamentals of parallel robots with configurable platforms (PRCP), as well as the design and the kinematic analysis of those. The concept behind PRCP is that the rigid (non-configurable) end-effector is replaced by a closedloop chain, the configurable pla
