Classification and type synthesis of 1-DOF remote center of motion mechanisms

چکیده
Type synthesis of 1-DOF remote center of motion (RCM) mechanisms is the preliminary for research on many multiDOF RCM mechanisms. Since types of existing RCM mechanisms are few, it is necessary to find an efficient way to create more new RCM mechanisms. In this paper, existing 1-DOF RCM mechanisms are first classified, then base on a proposed concept of the planar virtual center (VC) mechanism, which is a more generalized concept than a RCM mechanism, two approaches of type synthesis for 1-DOF RCM mechanisms are addressed. One case is that a 1-DOF parallel or serial–parallel RCM mechanism can be constructed by assembling two planar VC mechanisms; the other case, a VC mechanism can be expanded to a serial–parallel RCM mechanism. Concrete samples are provided accordingly, some of which are new types. 2008 Elsevier Ltd. All rights reserved.

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...
متن کاملStructure Synthesis of 6-DOF 3-3 Decoupled Parallel Manipulators
In parallel manipulator design, usual 6-DOF PMs, like the Stewart platform, suffer from the disadvantages of difficult forward kinematics, coupled motion, and small workspace, so that the motion planing and control become very complicated and difficult to be implemented in real application. Most of the PMs with lower mobility are over-constrained when assembly errors are considered [1]. Therefo...
متن کاملType synthesis of 4-DOF nonoverconstrained parallel mechanisms based on screw theory
A systematic method is developed for the type synthesis of 4-DOF nonoverconstrained parallel mechanisms with three translations and one rotation inspired by the design of H-4. First, the motion requirements of primary platform and secondary platform of the 4-DOF nonoverconstrained parallel mechanisms are analyzed, and the conflict between the number of actuators and the constraint system for no...

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...
متن کاملType Synthesis of Low-dof Parallel Robots Based on Screw Theory
In this paper a new procedure for type synthesis of low-DoF parallel robots based on screw theory is presented. The motivation of these work is that for many industrial applications, in particular in the machine-tool field, less than 6 degree of freedom (6-DoF) may be needed to complete the task. For example, for milling operation in the machine-tool domain, the rotation of the platform around ...
