Rigid origami is a branch of origami which is concerned with folding structures using flat rigid sheets joined by hinges. That is, unlike in traditional origami, the panels of the paper cannot be bent during the folding process; they must remain flat at all times, and the paper only folded along its hinges. A rigid origami model would still be foldable if it was made from glass sheets with hinges in place of its crease lines. However, there is no requirement that the structure start as a single flat sheet – for instance shopping bags with flat bottoms are studied as part of rigid origami. Rigid origami is a part of the study of the mathematics of paper folding, and rigid origami structures can be considered as a type of mechanical linkage. Rigid origami has great practical utility.

How origami is inspiring new kinds of emergency shelters
Engineers have come up with a way of designing structures based on the ancient art of origami. The structures can be put up with by inflation, fold up flat for storage and transport, and can be made of strong, rigid materials. One hope is that these structures could be deployed in disaster
