Stealthy Remote-Controlled Drone Can Sneak Through Windows, Vents
This "Quadrotor Unmanned Aerial Vehicle" was created by Daniel Mellinger, Dr. Nathan Michael, and Dr. Vijay Kumar at the GRASP Lab at the University of Pennsylvania. What makes the Quadrotor special? It can maneuver just about anywhere, then perch itself upside down, waiting the right moment to strike. And you'll probably never even know it was there.
Humanoid terminators, you've officially been usurped: If the robot apocalypse is coming, it's probably going to be led by these things and a pack of Big Dogs.
