This robot can complete a Rubik's Cube in 1.02 seconds.
The fastest human takes more than four times as long – a 14-year-old called Lucas Etter became the first person to "break the five-second barrier" in November last year.
Someone on Reddit has pointed out that the cube has little holes drilled in it to let the robot's arms turn it.
However, there doesn't seem to be anything in the World Cube Association's guidelines which disallow that. The robot's builders are going to submit it to the Guinness Book of World Records.
