Rex cube flip two centers12/14/2023 That's a long sequence, but it's not hard to memorize the basic idea. The key move here is Bi,2|R|,Ci,Ai,C,A,2|R|,2B,|Ri|,B,D,Bi,Di,|R|,2Bi,2|R|,C,A,Ci,Ai,2|R|,B,|Ri|,B,D,Bi,Di and a varient of this for the other spike-pair set. I always make the 3 remaining sides a strip (i.e., not pair-wise adjacent.) The next step will address the reamining 3 sides. Solve both spike-pair sets.Įasily solve 3 of the 6 sides using sliver tri-cycles. It's really the same basic sequence strategy in all cases. After positioning the remaining pairs strategically, make a setup move, then a tri-cycle, just as you've been doing all along, so that undoing the setup-move completes the step for a single spike-pair set. If there are 3 remaining pairs, solve them all simultaneously. If there are 2 remaining pairs, use a similar strategy to turn it into 3 remaining unsolved pairs. This strategy works for a single set of spike-pairs up until the last 2 or 3 remaining pairs. Make a setup move to complete a pair (by matching 2 spikes of the same color), then tri-cycle an unsolved pair into the position of the solved pair, therey-by kicking out the solved pair into a safe location, then undo the setup move. There are 2 spike-pairs per face, one in each set. There are 2 sets of spike-pairs, each having 6 pairs, 1 per face. Then, though not necessary, you can temporarily solve the center positions again to see that they solve without a problem. If there becomes two remaining centers that need to be swapped, use X,2|R|,X with X=2,C. In this step we temporarily position the centers. Solving the puzzle from here on means mastering these tri-cycles in all variants, forward and backards. A simple tri-cycle of the edges finishes the final layer.įrom here on we only use sequences of the form X,Y,Xi,Yi to tri-cycle slivers about the cube while preserving the solved edges. Start with one side of the cube, then do the other. In the steps that follow, we are going to let A=LFU, B=RFU, C=RBU and D=LBU. Sub1 Reloaded consisted of three main parts: a system of camera sensors to determine the cube’s combination, a microcomputer that solved the puzzle and six motorized arms to spin the cube into a solved position.The method I show here is an alternative to a simpler and easier method known as the peddle-flip method. The company behind the robot, Infineon, wanted to show off its microchips and a new microcontroller meant for self-driving vehicles. In Germany, a robot named Sub1 Reloaded demolished those records, too. The officially-recognized Rubik’s cube world record belongs to Lucas Etter, who, at the age of 14, in solved a cube in 4.904 seconds in 2015.īefore the Munich expo, machines had previously cracked the 1-second mark, though not by much. To humans fleet of mind and finger, it is possible to solve a Rubik’s cube in a matter of seconds. The goal is simply to put the colors back again. Those sections can be scrambled into more than 43 quintillion combinations.
