Imaging using Lego (in this case, Lego Mindstorms) to build a robotic device that, with the assistance of a smartphone, is capable of solving a Rubik’s Cube in a world record-setting time. Now watch the video above and feel bad that you didn’t do it first.
Two English engineers, David Gilday and Mike Dobson, have set a world record with their machine, which they call the Cubestormer 3, which was able to completely solve a Rubik’s Cube in under 4 seconds. The final time was 3.253 seconds, a time that will dismay actual human record attempt hopefuls.
The duo used Lego Mindstorm components, along with a collection of robotics bits and pieces, as well as a custom app running on a Galaxy S 4. The biggest hurdle for them was apparently getting the smartphone to talk to the motors quickly enough to make sure nothing went pear-shaped during the record attempt. As you can see, they got it right. Now they’re off to beat their current time.
