New Robik Rubik's Cube Speed ​​Record

In recent years, lovers of robotics and simply enlightened people can observe a very happy trend of progress in the field of engineering developments. Technological solutions that previously seemed applicable only to the scale of large and expensive production are becoming more and more accessible every day.

The building of the Rubik's cube for speed has long become a kind of sport, but in recent years puzzle lovers have become even more clearly active. The very same toy began to be used in robotics, including in order to demonstrate the speed and accuracy of data processing and the execution of simple tasks by robots. The conditions of the problem are as simple as possible: a robot, in conjunction with any available software and equipment, must quickly fold a Rubik's cube 3x3x3 in the minimum number of revolutions of the faces.

The speed of the Rubik's cube assembly by robots has been gradually increasing since the beginning of the decade. Back in 2011, CubeStormer2 assembled the puzzle in 5 seconds . Three years later, the new model of the robot, CubeStormer3, cope with this task in just 3.253 seconds .

The last record for the Rubik's Cube assembly belonged to the robot by Jay Flatland and Paul Rose: the best assembly time officially recorded by observers was 0.900 seconds. In other, non-scoring attempts, the robot could cope with the task even faster. Achievement was recorded in February of this year.


But this record is already broken. Back in February, there was talk about the fact that there is another contender for the title of "the fastest robot to build the Rubik's cube" - the development of Albert Beer and Infineon company called "Sub1". It was this machine that achieved the maximum result: the fixed speed of the Rubik cube assembly performed by “Sub1” was 0.637 seconds.


This time, the engineers achieved success not at the expense of the original design (in “Sub1” it is, in fact, a classic for this kind of task), but thanks to the new AURIX microcontroller. Infineon, which created Sub1, developed AURIX for automotive autopilot. Using the same development in the robot collector Rubik's Cube is an excellent demonstration of the speed with which the microcontroller is able to process data and send signals.

Achievements of people in the field of high-speed assembly of a Rubik's cube sized 3x3x3 are much more modest. The latest record is 4.74 seconds for the best attempt at an average of 6.89 seconds.
