Solving Rubik's cube is a difficult task but robots handle it with ease. A lego robot named Cubestormer solved Rubik's cube in only 3.253 seconds. It broke previous record of 5.27 set by its previous model: the Cubestormer 2.
Cubestoremr 3 is run by the Samsung Galaxy S4's Scta-core version. The phone gives instructions to the robot on solving the cube. This solving time can be lessened if the designers David Gilday and Mike Dobson use a faster processor may be Snapdragon latest mode.
