First they came for Jeopardy!, then they came for our vibraphones. We still own baseball, but the "humans only" list has grown one shorter now that the Carnegie Mellon Robotics Club has birthed Vibratron, a robotic vibraphone. Vibratron's Arduino Mega controls 30 solenoid gates that drop steel balls onto the vibration keys, producing a note; an Archimedes screw recycles the bearings, turning them once more into sweet, sweet music. We should also note that Vibratron doesn't put decent, salt-of-the-earth vibraphonists out of work. That cacophony in the video is "Circus Galop," written for two player pianos and impossible for humans to perform -- and still pretty hard for humans to listen to. See, Vibratron is here to help you, fellow humans. At least for now. Click the video above to get acquainted.
