HMPS - YuMi vs Rubik's Cube
Published on May 26, 2016
ABB's robot, YuMi, is one of a new breed of "cobots". These collaborative robots are designed to be safe enough to be around people. This opens up avenues for humans and robots to work together more closely, a scenario not previously possible with standard industrial robots. YuMi's arms have 7 degrees of freedom each, making the entire system a 14 axis robot. This provides a great deal of flexibility of movement, allowing more complex functions to be carried out.
In this application a Cognex Insight camera is identifying the position and orientation of the Rubik's Cube on the table. YuMi picks up the cube and analyses each face to determine the position of each coloured square. The RAPID program then formulates a sequence of moves to solve the puzzle and match up all the colours. YuMi executes these moves, requiring accuracy and coordination between the arms.

Engineering a massive Rubik's Cube
Published on Jul 19, 2016
When inspiration hits, it’s hard to ignore. That’s why a group of four Michigan mechanical engineering students decided to craft their very own senior design course. It just so happens that their course was designing and building a massive human controlled Rubik’s Cube. Follow the four of them through conception to completion of their initial design, and see what it takes to scale something that fits in the palm of your hand to a four by four foot, 1500 pound tribute to one of the world’s most beloved puzzles.
The World's Largest Free Standing Rubik's Cube
Published on Apr 13, 2017
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.”
