This is up there in "performance art" because the robot would take forever. Mitsubishi apparently has a robot that can do a normal cube solve in ~0.3 seconds (https://www.livescience.com/technology/robotics/this-ai-powered-robot-has-worked-out-how-to-solve-a-rubiks-cube-in-just-0305-seconds https://www.livescience.com/technology/robotics/this-ai-powe...), which they developed to show off their precision manufacturing. They mention one run that did 15 moves in 0.204 seconds. At that rate it works out to ~19 billion years to run through all positions.
- hinkley 2y agoDon’t forget leap years! What’s 18.6 billion years between friends? I’m sure they could make it go faster but I suspect the reason the robot works at this speed is the friction in the cube only raises the temperature a few degrees before the cube settles and can cool down. And pausing for 60 milliseconds so the human eye has time to register the cube positions probably doesn’t suffice. You could probably get it down to a billion years without reducing it to just a blur. A couple million if you point a bunch of high speed cameras at it and show the last fifty moves on screens next to the machine. Or 30 machines all showing 1/30th of the cycle.
