I clipped this from a forum on the subject. Since this portion from the chat gave a link, I am posting the remarks and the reference here. Those writing science fiction, futuristic or fantasy stories may find this information helpful.
Swarms of cyborg insect drones are the future of military surveillanceThe kinds of drones making the headlines daily are the heavily armed CIA and U.S. Army vehicles which routinely strike targets in Pakistan – killing terrorists and innocents alike.
But the real high-tech story of surveillance drones is going on at a much smaller level, as tiny remote controlled vehicles based on insects are already likely being deployed.
Over recent years a range of miniature drones, or micro air vehicles (MAVs), based on the same physics used by flying insects, have been presented to the public.
The fear kicked off in 2007 when reports of bizarre flying objects hovering above anti-war protests sparked accusations that the U.S. government was accused of secretly developing robotic insect spies.
After writing this post, I stumbled onto a humorous video about microbots, including a photograph of a mosquito-sized drone that can extract a DNA sample from a human covertly. As TheTrutherGirls says, “Get a fly swatter and screens!” Enjoy the video!
And just to feed your paranoia, here’s a video from a NSA whistleblower. He confirms the government’s program of domestic intelligence collection. Just think of all this stuff as research for your novel about nanobots and their nefarious controllers. :-p
