The present paper is about a detailed review of planar parallel manipulators. Planar parallel
manipulators have three degrees of freedom, one linear motion along the X-direction, one …

This paper proposes a unified method for the elastostatic stiffness modeling of
overconstrained parallel manipulators. First, the constraint wrench systems of an …

Solving the forward kinematics of parallel robots efficiently is important for real-time
applications. However, it remains a difficult problem due to its high nonlinearity. This paper …

This study is concerned with the surface integrity of Inconel 738LC parts manufactured by
selective laser melting (SLM) followed by high-speed milling (HSM). In the investigation …

This paper investigates the problems of kinematics, Jacobian, singularity and workspace
analysis of a spatial type of 3-PSP parallel manipulator. First, structure and motion variables …

Mecanum wheels are widely used in omnidirectional vehicles, but their arrangements are
usually arbitrarily selected. We find that the arrangement of Mecanum wheels influences the …

The elastostatic stiffness performance of a 2 P UR-P SR (S: spherical joint; U: universal joint;
R: revolute joint; P: prismatic pair) overconstrained parallel mechanism with two rotational …

Abstract Machine tools with a parallel–serial (hybrid) kinematics structures represent a
compromise solution that combines the advantages of traditional serial and parallel …

Industrial robots have advantages of large workspace, compact structure, and good
flexibility, but the stiffness of the robot is relatively weak due to the compliance of reducers …

This paper combines a new structure of artificial neural networks (ANNs) with a 3rd-order
numerical algorithm and proposes an improved hybrid method for solving forward …
