SUMMARY:Computational Biomimetics of Winged Seeds
DESCRIPTION:Qiqin Le (Shanghai Qi Zhi Institute); Jiamu Bu (Tsinghua Unive
 rsity); Yanke Qu (Peking University); Bo Zhu (Georgia Institute of Technol
 ogy); and Tao Du (Tsinghua University, Shanghai Qi Zhi Institute)\n\nWe de
 velop a computational pipeline to facilitate the biomimetic design of wing
 ed seeds. Our approach leverages 3D scans of natural winged seeds to const
 ruct a bio-inspired design space by interpolating them with geodesic coord
 inates in the 3D diffeomorphism group. We formulate aerodynamic design tas
 ks with probabilistic performance objectives and adapt a gradient-free opt
 imizer to explore the design space and minimize the expectation of perform
 ance objectives efficiently and effectively. Our pipeline discovers novel 
 winged seed designs that outperform natural counterparts in aerodynamic ta
 sks, including long-distance dispersal and guided flight. We validate the 
 physical fidelity of our pipeline by showcasing paper models of selected w
 inged seeds in the design space and reporting their similar aerodynamic be
 haviors in simulation and reality.\n\nRegistration Category: Full Access,
