New record! Robot solves Rubik's Cube in less than a second Solving a Rubik's Cube is an impressive feat by itself, but now, a robot can do it in record time, cracking the 3D puzzle about 10 times faster than the human who holds the world record. In just over half of a second (0.637 seconds), the Sub1 Reloaded robot made each side of the Rubik's Cube show a single color. This breaks the previous record of 0.887 seconds achieved by an earlier version of the same machine using a different processor. German technology company Infineon staged the record attempt at the Electronica trade fair in Munich this week, as a way to highlight its self-driving-car technology. The company provided one of the Sub1 Reloaded robot's microchips.
