A ROBOT made from Lego and powered by a smartphone has beaten the Rubik's Cube-solving record by completing the puzzle in little more than three seconds.

Inventors Dobson and Gilday said that even they were surprised how quickly their robot was able to solve the puzzle: "We knew CubeStormer 3 had the potential to beat the existing record but with the robot performing physical operations quicker than the human eye can see there's always an element of risk," said Gilday.
