Radio-seeking drone

TRAQ is a senior project from a group of Northeastern University engineering students; it's a quadcopter that seeks out and homes in on radio signals. As they write, "The quadcopter's potential applications include disaster relief, surveillance, search-and-rescue, and stolen goods recovery."

I'm interested in the technology as a way to get cameras automatically directed to hotspots in places like Gezi Park -- the drones could automatically focus on police based on their emergency radios, ensuring that the cops were always in shot.
