看图说话：世界最大的魔方在美国密歇根大学落成典礼

2017年4月，世界最大的单人可操作的魔方在美国密歇根大学落成。

该魔方有约2米高，1500磅重，由密歇根大学机械工程系的学生完成，从设想、设计到制造安装，用了3年多的时间。

这个大魔方是典型的“交互式机械艺术作品”。

1）看看，这个大魔方比人要高

2）设计者（制造者或典礼策划者）给魔方来个“两转”造型（先转U层，再转R层）

3）她有个梦，今天实现了

4）整个视频2分半

5）单人可轻松转动，魔方里面有轴承

6）看看，这大魔方不着地，六个面都可以转动

7）这是魔方内部，看看还是有些难度的

8）安装过程，也需要脚手架

9）1500磅，也算是中等重型设备啊

10）剪彩之后

TheWorld's Largest Free Standing Rubik's Cube

Agiant Rubik’s Cube newly installed on the University of Michigan’sNorth Campus is believed to be the world’s largest hand-solvable, stationaryversion of the famous puzzle. Since it was invented in 1974, the Rubik’s cubehas become the world’s best-selling puzzle game—one that introduced andpromoted mathematical thinking to generations. Solving it involves recognizingpatterns and developing and implementing algorithms. The colorful, new cube ismeant to be touched and solved. The students worked hard to figure out amovement mechanism that would enable that. They realized they couldn’t simplyscale up the approach a handheld cube relies on because the friction would betoo great. So to keep friction minimal, they devised a setup that utilizesrollers and transfer bearings. “There is no other human-manipulable cube likethis, to the best of our knowledge. That said, it is not technically thelargest cube. We're aware of a larger cube that requires the user to literallyroll it on the ground to solve and rotate the faces. None of that is requiredby our stationary design. So to be very precise, it is the world's largeststationary, human manipulable Rubik's cube.”
