The World's Largest Free Standing Rubik's Cube
A giant Rubik’s Cube newly installed on the University of Michigan’s North Campus is believed to be the world’s largest hand-solvable, stationary version of the famous puzzle. Since it was invented in 1974, the Rubik’s cube has become the world’s best-selling puzzle game—one that introduced and promoted mathematical thinking to generations. Solving it involves recognizing patterns and developing and implementing algorithms. The colorful, new cube is meant to be touched and solved. The students worked hard to figure out a movement mechanism that would enable that. They realized they couldn’t simply scale up the approach a handheld cube relies on because the friction would be too great. So to keep friction minimal, they devised a setup that utilizes rollers and transfer bearings. “There is no other human-manipulable cube like this, to the best of our knowledge. That said, it is not technically the largest cube. We're aware of a larger cube that requires the user to literally roll it on the ground to solve and rotate the faces. None of that is required by our stationary design. So to be very precise, it is the world's largest stationary, human manipulable Rubik's cube.”
