MindCub3r featuring LEGO® MINDSTORMS® EV3

108,105 views 10 months ago
MindCub3r is a new LEGO® Rubik's Cube® solver that can be built from a single MINDSTORMS® EV3 set Item: 31313.

MindCub3r is more efficient than previous versions of MindCuber that were created with MINDSTORMS NXT. It is currently able to solve the Rubik's Cube puzzle in an average of about 24 moves in 1 min 50 secs.

This efficiency is enabled by the higher performance ARM9 processor and significantly greater 64MB RAM in the EV3 than the previous NXT. A new software algorithm was developed especially for the robot with a four-phase lookup-table driven algorithm requiring approximately 5MB RAM.

I'd like to thank many people who made this video possible including the LEGO MINDSTORMS team and members of the LEGO MINDSTORMS Community (you know who you are!).

Special thanks to John Hansen for his great work on BricxCC and for his support in enabling me to use pre-release test versions of his IDE. See: http://www.youtube.com/watc...

Build instructions and software are now available on:

As always, many thanks to my very good friend Mike Dobson (co-designer of CubeStormer II and CUBESTORMER 3) for allowing me to use one of his great tracks for this video, "Cube-essence". Thanks Mike :)
