Berlin: A robot has successfully solved the Rubik’s Cube in just 0.637 seconds, beating the previous Guinness World Record achieved by an earlier version of the same machine. The Sub1 robot had achieved the record for the Fastest robot to solve a Rubik’s Cube back in January, solving the famously difficult puzzle in just 0.887 seconds. The machine “Sub1 Reloaded” beat that record with the help a new, faster microchip.
The Rubik’s Cube consists of six faces, each having nine squares of a colour that can be turned in opposing directions. The object is to rotate the faces until they have returned to the original position. More than 43 quintillion combinations of the colored squares are possible. The same number of cubes could cover our planet in 275 layers of cubes. The Earth would then be covered with an 20-metre-high layer of Rubik's Cubes.
The fastest time to solve a Rubik’s Cube by a person is 4.904 seconds, which was achieved by teenager Lucas Etter in November last year. “We want to show that problems can be solved much more efficiently using microelectronics,” said Gregor Rodehueser, spokesman of German semiconductor manufacturer Infineon Techno-logies which developed the microchip for the robot.
