A small insect or a mosquito over your ear may now be much more than simply annoying. Those could easily be micro drones which now come in a swarm of bug-sized flying spies.
In an effort to create a hard-to-detect surveillance drone that will operate with little or no direct human supervision in out of the way and adverse environments, researchers are mimicking nature.
The US Department of Defense has turned its attention to miniature drones, or micro air vehicles long ago.
As early as in 2007 the US government was accused of secretly developing robotic insect spies when anti-war protesters in the US saw some flying objects similar to dragonflies or little helicopters hovering above them. No government agency has admitted to developing insect-size spy drones though some official and private organizations have admitted that they were trying.
