Infineon said more than 43 quintillion combinations of the Rubik's Cube's colored squares are possible. That same number of cubes would cover Earth in 275 layers, resulting in an approximately 65.6-foot-high (20 meters) layer of Rubik's Cubes, the company added.
The record-breaking attempt began with the press of a button. Sensor cameras on the machine had their shutters removed, and the computer was then able to detect how the cube was scrambled. The computing chip, or the "brain" of the machine as Infineon called it, then determined the fastest solution. Commands to execute the solution were sent to six motor-controlled arms.
While every Rubik's Cube can be unscrambled with just 20 movements, Infineon's engineer Albert Beer did not design the computer to use the fewest moves. Instead, the company said the machine was programmed to achieve the best time, allowing the Sub1 Reloaded to take extra moves to reach its goal.
