A quick survey of the desks at Pi Towers reveals thirteen Rubik’s Cubes in various states of done-ness. Gordon’s brain doesn’t work without a cube to play with, and Ben appears to breed them in his desk drawers.
(Rubik’s cubes are not the worst thing that breeds in Ben’s drawers.)
With this Cube Solver from Maxim Tsoy and Wilbert Swinkels, we finally have a way to completely replace both Gordon and Ben with robots.
The Cube Solver uses a Compute Module to run the cube solving algorithms and move the grips and motors; you can find full details of the build and all the code you need at Maxim’s blog if you ever feel the need to replace the cuber in your life with a more compact solution.
