Flying Snakes to Help Design Robots

Always interested in examples of biomimicry ... here an unusual direction.

 Flying Snakes Help Scientists Design Robots

AIP Publishing, December 13, 2022

Researchers at the University of Virginia (UVA) and Virginia Polytechnic Institute and State University modeled the dynamics of flying snakes, in order to design robots that can replicate their gliding motion. Flying snakes undulate side-to-side as they glide from the tops of trees to the ground; the researchers analyzed the reptiles' lift production mechanism using a computational model based on data from high-speed video. The model includes the cross-sectional shape of the snake's body, through which the researchers learned leading edge vortices last longer at the curves in the body before being shed. The researchers hope such insights will improve their understanding of gliding motion, leading to a more optimal design for gliding snake robots.  ... '
