This paper presents a critical review on the calculation of the mobility, the main structural
and kinematic parameter of a mechanism. We focus on a brief presentation and a critical …

The paper presents a critical review of the well known Chebychev–Grübler–Kutzbach's
criterion for global mobility calculation of multi-loop mechanisms. We emphasize on the …

Parallel robots are closed-loop mechanisms presenting very good performances in terms of
accuracy, velocity, rigidity and ability to manipulate large loads. They have been used in a …

This paper addresses the architecture optimization of a three-degree-of-freedom
translational parallel mechanism designed for machining applications. The design …

The paper presents a new structural synthesis approach of fully-isotropic translational
parallel robotic manipulators (TPMs) based on the theory of linear transformations. A TPM is …

This paper introduces a 3-DOF translational parallel manipulator called Cartesian Parallel
Manipulator (CPM). The manipulator consists of a moving platform that is connected to a …

This paper presents a parametric stiffness analysis of the Orthoglide. A compliant modeling
and a symbolic expression of the stiffness matrix are conducted. This allows a simple …

This article presents the position analysis of a new family of 3-limbed 3-dof parallel
manipulators, whose output links exhibit a motion of pure translation with respect to the …

Although stiffness analyses of specific parallelogram-type parallel manipulators (PTPMs)
have been presented by several researchers, an algebraic expression is still needed to …

This paper deals with the multi-objective path placement optimization for Parallel Kinematics
Machines (PKMs) based on energy consumption, actuator torques and shaking forces. It …
