Programmable Fluidic Networks Design for Robotic Origami Sequential Self-Folding

Jamie Paik, Mustafa Mete, Zhenishbek Zhakypov, Julien Fiorentino

Self-folding enables compact, deployable and reconfigurable structures for close and far remote applications. As the degree-of-freedom in achieving folded shapes is dictated by the number of actuators, distributed on a quasi-2-D lattice, their design remai ...
