Multiloop origami inspired spherical mechanisms

Structure of Parallel Mechanism Combined with Waterbomb-Base-Inspired Origami

“…The creases consist of two types. The first type has a convex shape called Mountain creases, denoted by M, and the second type has a concave shape called Valley creases, represented by V [7,8]. Waterbomb-base origami consists of six planes and six creases.…”

“…Thus, the waterbomb-base origami form contains six revolute pairs and six links. Barreto et al [8] made an analogy between the spherical mechanism and the origami vertex as a concept of mechanism design.…”

Synthesis analysis of the morphologies of convex polygonal tubular origami structures based on Yoshimura origami patterns

“…2 Origami theory based on these well-known origami models is widely used in engineering research, spatially extensible mechanisms, soft and flexible robots, and mechanical metamaterials. [3][4][5][6][7][8][9][10][11] Moreover, complex and variable crease geometry relationships have contributed to a variety of spatial origami structures, creating unique properties, such as being reconfigurable, having a negative Poisson's ratio, and having a large folding ratio [12][13][14][15][16] ; therefore, there is room for the exploration and application of origami structure research. Based on the above content, some researchers have begun to focus on new origami structure construction methods to design new origami structures for use in practical applications.…”
