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.
The 1,500-pound, mostly aluminum apparatus was unveiled today on the southwest corner of the second floor of the G.G. Brown Building. It was imagined, designed and built by two teams of mechanical engineering undergraduate students over the course of three years
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.
