What's even cooler than flying robots? Flying robots that work in tandem to grasp and transport objects across a room. Individually, the robots can't lift much but swarm them together and watch their strength grow.
The GRASP Lab at UPenn (yep, these same guys) placed a claw-like gripper on the bottom of each quadrotor so it could grab objects and developed a control method, basically swarm robotics, which allows the quadrotors to team together in any number and configuration.
I want at least 10 of these quadrotor flying robots in my future home. One can bring my iPhone to me. Four could team together to bring my laptop. And the rest can bring me beer. [BotJunkie]
