For those interested, the full source-code is available here: (robot), (solving algorithm). This succeeds my own mirrcub3r ( also featured in the 2019 Royal Institution Christmas Lectures as the new fastest Lego-based Rubik's Cube solving robot in the world. Most, obviously it can now turn all 6 sides making solutions ~12% shorter on average. This is however by far not the only improvement that has been made. First, the now exclusively Technic-based construction is a lot more stable and centers the cube much better allowing even more aggressive turning while at the same time maintaining noticeably better consistency. Further, the solving algorithm has been carefully revised, making it even more efficient and implementing some extra features. One of those is the ability to return more than a single solution thus allowing post-selection ba
