In this paper, the kinematics, dynamics, and load distribution algorithm of a 4-PPPS
redundantly actuated parallel manipulator are investigated with the screw theory. For the …

This paper presents a CGA-based approach to the inverse displacement of the S-PMs
composed of two PMs. Two novel S-PMs including (2-SPR+ RPS)+(2-RPS+ SPR) and (2 …

Although the serial-parallel manipulators (S-PMs) formed by the symmetric 3-RPS and 3-
SPR PMs have been widely studied, the terminal constraint and mobility criterion for this …

Pointing mechanisms are widely used in aerospace fields. In order to make the pointing
mechanism more adaptable and make the structure more compact and lightweight, a novel …

Complete kinematic is an essential and a challenging work for series–parallel manipulators
(S–PMs). This paper studied the complete kinematic of a 2 (3-SPS+ UP) series–parallel …

Parallel mechanisms are finding wide applications in manufacturing. The design
methodology of parallel mechanisms is generally considered as a complex procedure. Many …

The structure design of divertor Multi-Functional Maintenance Platform (MFMP) actuated by
hydraulic system for China Fusion Engineering Test Reactor (CFETR) was introduced in this …

A serial-parallel dynamics simulator based on serial-parallel manipulator is proposed.
According to the dynamics simulator motion requirement, the proposed serial-parallel …

Construction robots with mobile systems are an integral part of automatic building
processes. However, with the vigorous development of prefabricated buildings, traditional …

This paper discusses the issue on mobility analysis of parallel mechanism. The analysis is
focused on the two-rotational and one-translational 2UPR-SPR parallel mechanism which …
