In October of 2011, Mike Dobson and David Gilday’s CubeStormer II robot, built from Lego kits and powered by a Samsung Galaxy S2, set the world record for solving a Rubik’s Cube: 5.27 seconds. That time just narrowly defeated the best ever human time, marking the first time a robot had done so.
Now the two robot builders are at it again. At last weekend’s Big Bang Fair in Birmingham UK, the team brought their next creation: the CubeStormer 3. Again built from Lego mechanical and robotics parts and this time powered by a Samsung Galaxy S4, the robot shattered the record set by the CubeStormer II by solving a Rubik’s Cube in only 3.253 seconds – which is not only faster than the CubeStormer II, but also faster than the fastest human time of 5.55 secondsset by Mats Valk.
