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

The aesthetics of this are great. Nice job.

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...

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

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.)

Ahh right, I forgot the center piece defines the face color, thanks.

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