A Few More Amazing NXT Robots...

These projects, like the Rubik's cube solving creation in the post below, use computer programs to determine what to do.

Sudoku Solver
This project is epic. I couldn't find who it was made by, but his YouTube account name is "tiltedtwister". Also, if you are interested, here is his website. It includes a ton of information about his Sudoku Solver, and also about another project he made to solve Rubiks cubes... He was even generious enough to post building instructions. :)



Mindstorms NXT Portrayer Robot
This next project was made by Daniele Benedettelli (YouTube account name "mentulatus"). He has a fascinating website.

Rubik's Cube Solver

Mindstorm robots that solve Rubik's Cubes never fail to amaze me. I can only imagine how complex the programming is... and even building it to be that fast, efficient, and accurate must be a challenge. However, many people have done it. Recently I found a video of an amazingly fast robot created by Mike Dobson:





Also, here is a discription as it was posted on YouTube:

The Worlds Fastest Lego Mindstorms RCX Speedcubing Robot. Built entirely from lego elements with a lego web camera to scan the faces of the cube, The solve engine (algorithm) running on the computer is provided by the incredible "Cube Explorer "software which also provides the colour recognition required to determine the exact location of each coloured square. Thanks to Herbert Kociemba for making his work available to anyone wishing to use it! Respect! "Cube Explorer" has the ability to produce very fast solutions to a successfully scanned cube, usually around 20 face turns! Doesn't sound a lot , but it is believed that around 20 turns are enough to solve ANY 3x3x3 cube combination. I'm still working on "CubeStormer" I would like to see it reach sub-10 and feel it's close to that. but reliability begins to suffer when you start to push things just that bit too far..... Special thanks to David Gilday for his assistance with the software interface to Cube Explorer.....Enjoy !
