[Tim] let us know about a video outlining some covert camera devices the Air Force is developing (dead link, try the Internet Archive version). The video takes a lot of time to explain induction to those who’ve never heard of it but we liked to see the bird-like concept animations. They’ve already developed cameras that will clamp on to power lines in order to use induction as a power source. Shown in the video is an eight-rotor quadcopter they’re hoping to use to deliver the camera covertly. But the animations show a winged robot similar to a hawk that has a camera for a head. Having seen some of the other flying devices in development this may not actually be that far off.
