A Lego robot breaks the world record by solving a Rubik's cube in 3 seconds

The device, called CubeStormer 3, has been presented at the fair of technology and engineering held in Birmingham

   A robot that works with Lego modules and a Samsung phone, has beaten the resolution record of a Rubik's cube, after taking to finish it in 3.253 seconds, according to the crediting editor of Guinness World Records, Craig Glenday.

The device, called CubeStormer 3, has been presented at the technology and engineering fair held in Birmingham. It has been created in 18 months with a Samsung Galaxy S4 smartphone and ARM processors as key elements.

   The S4 device is the "intelligence" component, which serves to analyze the cube and works with an Exynos 5 Octa application processor with an eight-core ARM big.LITTLE implementation, with four Cortex-A15 and four Cortex-A7 processors. After analyzing the cube, the phone orders four robotic hands to perform the manipulations.

Complex orders

The designers of this project have explained how the hands of the robot must be "incredibly precise" to move so quickly and without problems. "In addition to developing the solution, the processor has to instruct the robot to carry out the movements. This is more complex than it seems, because Cubsestormer 3 uses a speed cube that allows turns », they have indicated.

After this achievement, which can be seen in a video uploaded by the researchers , these experts indicate that their great challenge now "is to make this robot go faster".
