Sudoku-Solving Lego Robot: A Homegrown Toy with Smarts

By Corinne Iozzio Posted 08.27.2009 at 10:11 am 4 Comments

Here's a short list of things this robot can do that I can't: Write legibly. Solve a beginner sudoku puzzle in less than 10 minutes.

Swedish hacker Hans Anderson built this robot around the Lego Mindstorms System, which he's also used to make the Tilted Twister Rubik's Cube solver.

The 'bot first scans the board, and runs the data gathered through an a series of image-processing algorithms. After it's solved the puzzle, its motor guides it to fill out the solution by hand.

Too bad he's a little hefty for me to carry on the morning commute.

Amazed.. I don't really know what else to say. I am in Engineering Technology Teacher Education at Purdue University, so in short I will be teaching students how to use those very robot devices. I am going to have to see if I can figure this out and then maybe have an advanced course where the students get to try and solve a puzzle. Really cool. Thanks
