So far, the world record recognized by the Guinness Book of Records is 0.637 seconds, which was established by the German engineer Albert Beer and his Sub1 Reloaded robot.
The new record cuts the time in half: 0.38 seconds. Then you can see the video of the feat (if you do not blink).
Rubik
The researchers, including a student at the Massachusetts Institute of Technology, realized that they could solve the cube more quickly by using a different type of motor on their robot.
His contraption used two PlayStation Eye cameras from the old PS3 console to identify the cube's configuration. The motors took about 10 milliseconds to turn one side of the cube, with each movement that lasted approximately 15 milliseconds in total.
We realized that all the quick solvers in Rubik's cube used stepper motors and we thought we could do better if we used better motors.
