University of Pennsylvania Amazing Quad-Rotors

The fellows at the University of Pennsylvania did it again. They haven an even more impressive quad-rotor UAV demo that was done for their latest TED talk. This presentation summarizes their impressive work and features a rather surprising finale that you don't want to miss. So sit tight and watch till the end, it is worth it. http://www.youtube.com/watch?v=4ErEBkj_3PY
