The University of Pennsylvania posted this fun-to-watch video of flying robot quadrotors playing the James Bond theme on a variety of instruments. The slower instrument parts (keyboard, cymbal) are played by having the robot fly up and down. The faster lead part is played on a “couch guitar” they rigged up by running a series of strings tuned to the right series of notes across a couch frame. 3 robots take turns dragging a wire across the strings to play the sequence.
The whole thing is pre-programmed and the robots are acting autonomously. We’re one step closer to Skynet.
