This paper is to review all the discovered three-dimensional overconstrained linkage with
only revolute joints. There are 15 types well known and several types recently proposed …

This paper revisits the geometric constraints for a movable spatial RPRP mechanism and
further finds that it can be mobile as long as the link lengths and skew angles satisfy specific …

This paper deals with the type synthesis of variable-DOF (degree-of-freedom) single-loop
spatial mechanisms—a class of reconfigurable mechanisms that DOF may change. A …

In this paper, we present a virtual chain approach for the mobility analysis of multiloop
deployable mechanisms. First, the relative motion of the links of single-loop units in …

In this paper, a particular type of double-subtractive-Goldberg 6R linkage is obtained by
combining two subtractive Goldberg 5R linkages on the commonly shared 'roof-links' …

Traditionally, planar overconstrained mechanisms has been explained through special
geometry, which often lacks clarity and specificity. This paper addresses this challenge by …

A complete family of double-Goldberg 6 R linkages is reported in this article by combining a
subtractive Goldberg 5 R linkage and a Goldberg 5 R linkage through the common link-pair …

Planar mechanisms dominate modern designs of legged robots with remote actuator
placement for robust agility in ground mobility. This paper presents a novel design of robotic …

This paper addresses the assembly strategy capable of deriving a family of overconstrained
mechanisms systematically. The modular approach is proposed. It treats the topological …

While the animals' Fin-to-Limb evolution has been well-researched in biology, such
morphological transformation remains under-adopted in the modern design of advanced …
