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.
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.
We can make aircrafts that can navigate a maze of hallways.
I have this dream that the first responders to 911 calls will not be law enforcement personnel but robots. Robots can put eyes and ears on the scene much faster than you can with policemen or women.
