Bird sized airplane to fly like a swift
...ing means the wings can be swept back in flight by folding
feathers over each other, thus changing the wing shape and reducing the wing surface area. RoboSwift also steers by morphing its wings. Doing so, the micro airplane can perform optimally, flying efficiently and highly maneuverable at very high and ve...
