Lego robot beats world record for solving Rubik's Cube

Model outperforms the predecessor itself and performs assembly in just over three seconds

Can you solve a Rubik's cube quickly - or at least reach the final ? In 2011, Tecmundo told the story of a robot made with LEGO bricks and a mobile phone from Samsung that addressed this type of puzzle in a matter of seconds . Three years later , the record was broken tax at the time - the successor to the former holder of the trademark .

This is the robot Cubestormer 3 , which managed the feat of solving a Rubik's Cube in 3.253 seconds. The earlier mark , which belonged to Cubestormer 2 , was 62 % slower . Since the fastest movement made by a human which is 5.55 seconds is also easily exceeded.

Outside the building blocks , the model of time is controlled by a smartphone with the Galaxy S4 processor Exynos 5 Octa (quad-core ARM Cortex - A15 and Cortex - A7 four lower intensity ) . A custom app for Android makes the analysis of the magic cube and moves to be made ​​from an algorithm and sends the necessary unity of movement actions . The configuration of the communication between device and engines is considered the most complicated operation .

Those responsible for the project, engineers Guilday David and Mike Dobson, took 18 months to complete the project, carrying out the construction work in free hours. The next goal is to win an even better time, probably with a Cubestormer 4.
