“At the Micro-Aviary at Wright-Patterson Air Force Base, researchers rig the walls with super-sensitive motion capture sensors that track a tiny plane or helicopter's position ”within about a tenth of an inch,” according to researcher Greg Parker. Information from those sensors helps engineers develop “flapping-wing flight” drones — “very, very small flapping-wing vehicles,” in Parker's phrase. And how. One of the vehicles on display in the video, released by the Air Force Research Laboratory at Wright-Pat, is a robot dragonfly. It doesn't appear to be much more than a circuit board, a super-tiny motor and two insect-like wings”
Once fully developed and service the surveillance insects would be indistinguishable from the real thing and would be extremely difficult to spot with the naked eye. Providing both audio and video reconnaissance capabilities feeding real-time footage back to the control centre.
