This paper introduces a novel family of singularity-free kinematically redundant planar
parallel mechanisms that have unlimited rotational capabilities. The proposed mechanisms …

Type synthesis methods of parallel mechanisms or metamorphic mechanisms have drawn
rising interest for mechanism designers. However, existing synthesis approaches cannot …

In this paper, the stiffness of a 3-PSP spatial parallel manipulator is investigated. Unlike
traditional stiffness analysis, the moving platform is assumed to be flexible. Two analytical …

A four-degree-of-freedom (DOF) 3T1R parallel manipulator is presented in this paper. This
manipulator generates the family of so-called Schönflies motions, SCARA motions or 3T1R …

This paper introduces two general architectures of kinematically redundant planar parallel
mechanisms. Their kinematic models are analyzed, an analytic workspace determination …

This paper presents a comparison study on the dynamics of three planar 3-DOF parallel
manipulators, one with 3-RRR structure, and the other two with 2-RRR and 4-RRR …

Abstract A novel 5-degree-of-freedom (DOF) hybrid serial-parallel manipulator is introduced,
and the prototype of its parallel part has been manufactured for pratical testing purpose. The …

This paper addresses the inverse dynamics of three degrees of freedom (DOF) U-shaped
planar parallel manipulator having three legs consisting of prismatic–prismatic–revolute …

This paper proposes a modular lightweight three degrees of freedom (DOF) vertical planar
parallel robotic manipulator with a singularity free working region and that which is partially …

In this work, an optimization-based methodology for resolving the generalized forces for
kinematically-redundant planar parallel manipulators following a desired trajectory is …
