This is pretty mad. Not what you'd call groovy or with feel and dynamics, but  what these computer-controlled Quadrotors are capable of is impressive. 

What worries me more, is that here they are used for good, imagine what these things could do for an evil mind.....

Flying robot quadrotors perform the James Bond Theme by playing various instruments including the keyboard, drums and maracas, a cymbal, and the debut of an adapted guitar built from a couch frame. The quadrotors play this "couch guitar" by flying over guitar strings stretched across a couch frame; plucking the strings with a stiff wire attached to the base of the quadrotor. A special microphone attached to the frame records the notes made by the "couch guitar".

These flying quadrotors are completely autonomous, meaning humans are not controlling them; rather they are controlled by a computer programed with instructions to play the instruments.

Penn's School of Engineering and Applied Science is home to some of the most innovative robotics research on the planet, much of it coming out of the General Robotics, Automation, Sensing and Perception (GRASP) Lab.

This video premiered at the TED2012 Conference in Long Beach, California on February 29, 2012. Deputy Dean for Education and GRASP lab member Vijay Kumar presented some of this groundbreaking work at the TED2012 conference, an international gathering of people and ideas from technology, entertainment, and design.

The engineers from Penn, Daniel Mellinger and Alex Kushleyev, have formed a company called KMel Robotics that will design and market these quadrotors.
