Quadrotors Perform James Bond Theme
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.
