“…Figure 7 is an array of two 4R LEMs. The serially connected spherical 4R linkage discussed by Makhsudyan et al [21] is the basis of many of the following arrays. The output link of one 4R linkage is the input link to the other linkage.…”

Lamina emergent mechanisms (LEMs) are compliant mechanisms that can be manufactured from planar materials and are capable of motion out of the plane of manufacture. Spherical LEMs combine the unique motion of spherical mechanisms with the compactness and simple topology of LEMs. The fundamentals of spherical LEMs are discussed in this work. It is found that 21 of the 33 possible spherical 4R types can be spherical LEMs. A classification based on these 21 possible types is developed. This classification is used to predict motion capabilities of spherical 6R, and Equintet mechanisms. It is also applied to arrays of spherical mechanisms. The extreme compactness and sophisticated motion of spherical LEMs makes them candidates for application that are weight and volume sensitive and may find use in future surface morphing applications.

“…Some have named the mechanism as double-Hooke's-joint linkage [19] or 6R double-spherical over-constrained mechanism [20] and worked on the analysis of the mechanism. In the study of N. Makhsudyan et al [13], the comparative analysis and synthesis of six-bar mechanisms are discussed for two serially connected spherical four-bar linkages and two serially connected planar four-bar linkages. However, they placed the input and output axes of the spherical linkages parallel and the construction parameters of the first spherical and planar mechanism are selected by the authors and not determined by the kinematic synthesis procedure.…”
