Three objectives to address the fundamental challenges of adaptive origami design guided the effort 1 Identify metrics to quantitatively compare fold performance between polymeric materials, 2 Build an integrated optimization and mechanical analysis toolset to design and evaluate origami structures on both the macro and micro scale, and 3 Design, fabricate and demonstrate repeatable self-folding origami structures with remote activation capability. These three goals are highly complementary, requiring constant interchange of ideas and results, but at the same time allow work to progress in parallel until such time where they can be brought together into a complete demonstration of the concept. The cross directorate AFRL Laboratory Research Independent Research LRIR team RQ and RX ultimately envisions the addition of unforeseen capabilities bridging both TDs. The research developed the toolsets necessary to transfer the 2D to 3D reconfiguration capacity of origami into a design strategy for solving engineering challenges with mechanically relevant performance criteria.
