Kinematic Analysis of a Parallel-Sequential Structure Mechanism with Five Degrees of Freedom

Design and Analysis of a Three Degrees of Freedom Parallel Kinematic Machine

Kinematic Mapping and Forward Kinematic Problem of a 5-DOF (3T2R) Parallel Mechanism with Identical Limb Structures

The main objective of this paper is to study the Euclidean displacement of a 5-DOF parallel mechanism performing three translation and two independent rotations with identical limb structures-recently revealed by performing the type synthesis-in a higher dimensional projective space, rather than relying on classical recipes, such as Cartesian coordinates and Euler angles. In this paper, Study's...

Design and Kinematic Analysis of a 4-DOF Serial-Parallel Manipulator for a Driving Simulator

This paper presents the kinematic analysis and the development of a 4-degree-of-freedom serial-parallel mechanism for large commercial vehicle driving simulators. The degrees of freedom are selected according to the target maneuvers and the structure of human motion perception organs. Several kinematic properties of parallel part of the mechanism under study are investigated, including the inve...

Singularity analysis of a fully parallel manipulator with five-Degrees-of-Freedom based on Grassmann line geometry

This paper addresses the singularity analysis of a fully parallel manipulators with five degrees of freedom, based on line geometry. Starting from the inverse Jacobian matrix, which maps the moving platform’s twist to the actuated joint velocities, the singularity analysis is transformed into a search for specific geometric conditions, which apply, when the manipulator is in a singular pose. Fu...
