Just when you thought insects couldn’t get any creepier, the US Air Force has unveiled tiny finger-sized insect spy drones that would be undetectable to most. The example above can be used to inject toxins into enemies during wars.
Researchers have now developed bio-inspired drones with bug eyes, bat ears, bird wings, and even honeybee-like hairs to sense biological, chemical and nuclear weapons. And the U.S. isn’t the only country to have poured money into spy drone miniaturisation. France has developed flapping wing bio-inspired microdrones. The Netherlands BioMAV (Biologically Inspired A.I. for Micro Aerial Vehicles) developed a Parrot AR Drone last year – which is now available in the U.S. as a ‘flying video game’.
