Don’t normally post corporate-y stuff here, but this is really cool. AeroVironment announced on Thursday that they have created a UAV that uses only flapping wings for movement and control. From the press release:

The milestone was part of the Phase II contract awarded by the Defense Advanced Research Projects Agency (DARPA) to AV to design and build a flying prototype “hummingbird-like” aircraft for the Nano Air Vehicle (NAV) program.

The final concept demonstrator is called the ‘Nano Hummingbird’ and is capable of climbing and descending vertically, flying sideways left and right, flying forward and backward, as well as rotating clockwise and counter-clockwise, under remote control and carrying a video camera payload. During the demonstration the Nano Hummingbird flew in and out of a building through a normal-size doorway.
