A robot made of Lego, called Cubestormer 3 has broken the world record for solving a Rubik‘s cube, a record that belonged to its predecessor, Cuberstormer 2. The previous record was set in 2011 and the puzzle cube was solved in 5.27 seconds back then.
This series of robots was built with the sole purpose of solving the Rubik‘s Cube, and the latest record now stands at 3.253 seconds. It‘s a blistering time and you will struggle to see the moves being made in that short time.
According to creators, it uses the Samsung Galaxy S4‘s octa-core chipset, with the four ARM Cortex-A15 and four ARM Cortex-A7 cores each managing its own Lego Mindstorms actuator. Essentially, the phone is responsible for analysing how the cube is arranged, outlining the steps necessary to solve it, and then instructing the robot what to do.
It would be interesting to see how it would differ with other chipsets powering the calculations and analysis, for example using an Apple, Intel or Snapdragon chipset. Perhaps we will see that in the Cubestormer 4, but for now we have to be happy with the video demonstration of the world record attempt below:
