Feathered robotic wing paves way for flapping drones

By anders [dot] ortegren [at] biol [dot] lu [dot] se (Anders Örtegren) - published 24 January 2023 Christoffer Johansson with the robotic wing. Photo: Anders Örtegren. Birds fly more efficiently by folding their wings during the upstroke, according to a recent study led by Lund University in Sweden. The results could mean that wing-folding is the next step in increasing the propulsive and aerodyna
