This looks pretty awesome especially with the SDK. The hovering looks a little unstable compared to the hummingbird (<a href="http://spectrum.ieee.org/automaton/robotics/military-robots/darpa-concludes-nano-air-vehicle-program-we-wonder-whats-next" rel="nofollow">http://spectrum.ieee.org/automaton/robotics/military-robots/...</a>), but still very impressive. If they add support for wireless charging, you could have a pretty cool home monitoring system where the dragonfly roams about your home and returns to a charging station when needed
