Watch a Robot Solve a Rubik's Cube in 2.39 Seconds
A high school student made a bot capable of lapping the best human cubist.
The Rubik’s Cube record for robots has been smashed. Last month Florida high school student Zackary Gromko demonstrated his solving mechanism in front of a crowd of students gathered in a school gym.
“I have done it purely because this is what I love to do,” he told the Guinness World Records. “Even the best human methods up at this point can take 60 turns, but really any cube can be solved in less than 20 turns.”
The human record is a little more than twice as long, at 5.25 seconds (which is still nuts). American teen Collin Burns snatched the title, apparently by surprise, at an event in Doylestown, Pennsylvania, earlier this year. Robots retain the edge by not making unnecessary moves. There are no mid-solve surprises.
