Origami-based Reconfigurable Systems

Main content start

Origami, the ancient art of paper folding, allows the reshaping of planar materials or structures into intricate three-dimensional architectures. Origami-based reconfigurable systems enable various deformations and motions that can be applied to engineering fields including morphing structures, soft robotics, and biomedical devices.

Amphibious origami millirobot utilizes spinning-enabled locomotion for navigation capability in various on-ground and in-water environments with controlled delivery of liquid medicine and targeted solid cargo transportation functions

A small-scale origami crawler is developed based on a four-unit Kresling origami assembly by magnetic actuation with the capabilities of crawling in confined space, fast steering, and drug storage and release

Details

Inspired by the soft-bodied cephalopod biosystem, we engineer origami robotic arms to achieve multimodal deformations that integrate stretching, folding, omnidirectional bending, and twisting

Details

A magnetically responsive origami system is developed, possessing distributed, untethered control capabilities for integrating actuation, sensing, and computing

Details

Ring origami uses a snap-folding mechanism triggered by the buckling instability of rods under either bending or twisting load.  It is demonstrated that the snap-through instability leads to a self-guided folding behavior while showing a high packing ratio for rings with different geometries.

Here, we propose strategies to facilitate easy snap-folding of the hexagonal ring by a simple point load or localized twist or squeeze

Details

Motivated by this significant packing, we utilize a combination of experiments and finite element analysis to study effective folding strategies and packing abilities of various 2D and 3D hexagonal ring assemblies

Details

In this work, we use finite element analysis to systematically investigate how geometric parameters, loading locations, and loading methods affect the foldability and stability of hexagonal rings

Details

Motivated by the large area change and the self-guided deformation through snap-folding of the rings (circular, elliptical, rounded rectangular, and rounded triangular shapes), this work introduces ring origami assemblies with unprecedented packing ratios
