About

Tomohiro Tachi is a leading figure in computational origami and the mechanics of deployable structures, whose work bridges geometry, computer science, and engineering. His research focuses on the rigid foldability of crease patterns, the design of reconfigurable origami tubes, and the development of novel deployable systems with tunable mechanical properties. Tachi’s most impactful contribution is his foundational work on origami tubes with reconfigurable polygonal cross-sections (113 citations), which demonstrated how thin sheets can be assembled into deployable, mechanistically unique 3D structures with broad applications in robotics and aerospace. He also proved that deciding rigid foldability is NP-hard, a landmark theoretical result that established fundamental computational limits in origami design. More recently, he has explored graded Miura origami for crawling robots and grippers, and coupled origami tubes for stiff deployable cantilevers. His work on frustration-driven snap-through in Snapology systems (2025) continues to push the boundaries of transformable modular structures. With a career spanning theoretical complexity proofs to practical robotic applications, Tachi’s research has profoundly shaped how engineers and computer scientists think about folding, deployment, and reconfigurability.
