WebJan 17, 2024 · Fig. 1 Pigeon flight feathers are underactuated during wing flexion and extension. ( A) Birds morph their wings during flight by flexing and extending their skeleton. ( B) During morphing, as the wrist angle (θ w) extends, flight feathers pivot relative to the ulna bone, measured by primary and secondary feather angles (θ P and θ S ). WebJun 10, 2024 · Birds make morphing wings look effortless, bending in a wide range of planes and arcs. However, making unmanned aerial vehicles, or UAVs, with morphing wings is hard—typically, researchers manage only rough emulations of …
