At the Micro-Aviary, tiny helicopters will mix with robot dragonflies and hovering robo-hummingbirds in a space walled in by motion sensors that can track the drones that fly there to within about a tenth of an inch. Data from those sensors will not only evaluate the performance of the drones that are there but inform the design of future generations of flapping-wing drones and stealthy robot micro-helos. Tale an inside look at the lab below.
