It's a cool project, but also they're really underselling the amount of work put in to make it annoying.

There's a lot more detail describing the project in a couple of forum posts here: https://forum.pjrc.com/index.php?threads/sarcasm-an-over-eng...

This is fantastic, how did it not get confused by the blue logo on the cube in the video?

Western cubes always have white opposite yellow. Japanese cubes always have white opposite blue. (The center piece on each side can be considered "fixed" relative to all moves.)

I think you built a rubik cube solving machine just to show-case your acronym ;-) Super cool work.

Robotic solver is more of a physical problem than a mental one. A photo of the cube from top and bottom corners and you can solve it in a nanosecond
