DARPA has awarded an extension to AeroVironment for their work on the Nano Air Vehicle project. The prototype seen above, called Mercury, is an ornithopter which means it flaps it’s wings. It is the first to show controlled hovering. Look closely, there’s no rudder or tail. Mercury uses the two wings for both lift and control. Ornithopters themselves aren’t new, we’ve even covered them before. Usually they use the flapping wings for propulson and a tail to steer as they travel like an airplane. We would really love to see some detail shots of Mercury.
