Abstract

This demonstration, based on our full paper, presents a physical prototype of a transformable modular system constructed from Snapology origami. By introducing geometric frustration into assemblies of rhombic and regular triangular prismatic modules, we introduce a snap-through transformation from a 2D to 3D structure. The motion is programmed by activating selected out-of-plane fold hinges around a vertex, enabling either smooth or snapping motion. Participants can experience the snapping motion, triggered by in-plane actuation of rhombic modules. The demonstration showcases the design and fabrication of our Snapology and its potential for programmable mechanical metamaterials.}, booktitle = {Adjunct Proceedings of the 10th ACM Symposium on Computational Fabrication
