Bleep, blop, bloop! A Gibson 1st production run "Robot Guitar" in for a setup. What makes it a robot? It can tune itself automatically. Just pull the grey knob, select the tuning, press the center button, pluck the open strings and the tuning knobs take care of the rest. Certainly a novelty guitar but the auto tuning works fairly well. Sometimes it doesn't find the pitch on the first pluck but just hit the string again until the knob light of corresponding string turns green. A concern I would have on these guitars would be the availability of the proprietary Tronical tuning system components should something fail. Both the bridge and the stopbar are part of the system along with the motorized tuners and circuit board.
