SUMMARY:Computational Biomimetics of Winged Seeds
DESCRIPTION:Technical Papers\n\nQiqin Le (Shanghai Qi Zhi Institute); Jiam
 u Bu (Tsinghua University); Yanke Qu (Peking University); Bo Zhu (Georgia 
 Institute of Technology); and Tao Du (Tsinghua University, Shanghai Qi Zhi
  Institute)\n\nWe develop a computational pipeline to facilitate the biomi
 metic design of winged seeds. Our approach leverages 3D scans of natural w
 inged seeds to construct a bio-inspired design space by interpolating them
  with geodesic coordinates in the 3D diffeomorphism group. We formulate ae
 rodynamic design tasks with probabilistic performance objectives and adapt
  a gradient-free optimizer to explore the design space and minimize the ex
 pectation of performance objectives efficiently and effectively. Our pipel
 ine discovers novel winged seed designs that outperform natural counterpar
 ts in aerodynamic tasks, including long-distance dispersal and guided flig
 ht. We validate the physical fidelity of our pipeline by showcasing paper 
 models of selected winged seeds in the design space and reporting their si
 milar aerodynamic behaviors in simulation and reality.\n\nRegistration Cat
