LEGO machine solves Rubik's Cube in 3.6 seconds! [video]

Take a look at the "Cubestormer 3"! A machine built from LEGOs that can solve a Rubik's Cube in 3.6 seconds!  

"It turns out that the Samsung Galaxy uses a special app to take pictures the Rubik’s Cube’s faces, then calculates the most efficient way to solve the puzzle.

The phone then communicates with the software powering the Lego arms via Bluetooth, and sends it the solution. Boom!"

Impressive!
