As they constitute a substantial percent of deployable structures, scissor mechanisms are widely studied. This being so, new approaches to the design of scissor mechanisms still emerge. Usually design methods consider the ...

This paper presents a method of building deployable network assemblies derived from the single degree of freedom (DoF) over constrained Altmann linkage as a basic module. The method is based on assembling linkages with ...

In this paper, a novel two-dimensional scissor structure that transforms between concave and convex configurations is presented. The structure is designed by a method of assembling kite or anti-kite loops in the flat ...

The method of decomposition is a useful method for function generation with multi-loop mechanisms. Recently introduced correction methods applied together with the method of decomposition allows the designer to cancel out ...

Method of decomposition has been successfully applied to function generation with multi-loop mechanisms. For a two-loop mechanism, a function y = f(x) can be decomposed into two as w = g(x) and y = h(w) = h(g(x)) = f(x). ...

Determination of the safe working zone (SWZ) of a parallel manipulator is a one-time computational task with several permanent benefits. As this subspace of the workspace of the manipulator is free of both the loss- and ...

This paper presents the design of an assistive mechanism to be used for the rehabilitation of human arm. First the motions of two types of rehabilitation exercises are described. The motions are planar motions, so a planar ...

The path generation synthesis of a double-slider linkage is performed for a given elliptic curve. It is shown that there are ∞2 linkages that can trace the same ellipse. The formulation for obtaining all such linkages is ...

In approximate function generation synthesis methods, error between the desired function’s output and designed mechanism’s output oscillate about zero error while crossing the zero error margin at precision points. The ...
