 | | RCX+PC=Rubik's Cube Solver —Jonathan Brown
|
| | | All -- There's recently been some discussion in the Mindstorms Forums about the feasibility of producing an RCX-based Rubik's Cube solver. I am happy to report that I have finished a functional "late beta" version. You can see it at (URL) are (...) (23 years ago, 18-Apr-01, to lugnet.robotics, lugnet.robotics.rcx) !!

These are amazing - a must see and candidate for Site of the Week, no? Cheers, Ralph Hempel (23 years ago, 18-Apr-01, to lugnet.robotics, lugnet.robotics.rcx)
