Scientists Built a Robot From 40 Pigeon Feathers and It Flies Beautifully | Gizmodo

Scientists seeking to understand the mechanics of bird flight have constructed PigeonBot, a robot made from 40 pigeon feathers (and a few other components). While airplanes maneuver by altering their wing elements, birds can morph the shape of their entire wings to dive, bank, and coast through the air, increasing both their efficiency and agility. This new study on pigeon wings has not only provided a simpler model for how bird wings work but allowed engineers to integrate that knowledge into a nimble fly
