Normally, in the presence of radiation, communication links fail. But with autonomous robots, you don't need communications.
If you want a robot to maneuver aggressively, it has to be small. As you scale things down, the 'moment of inertia' - the resistance to angular motion - drops dramatically.
Robots are good at things that are structured.
Clearly, humans will always have a role to play in emergency response for law enforcement. But if there's an emergency, if there's a 911 call, the question is, do you want a human dashing off to respond to it right away?
Our nano-quadrotor robots are made to be as lightweight as possible: less than a fifth of a pound and palm-sized. They can do an aerial backflip in half a second, accelerate at two Gs, and fly rotor blade to rotor blade in three-dimensional formations - and they do all this autonomously.
