Lego robot solves your Sudoku puzzles

Robot scans puzzle, does the math, then physically writes the solution

Ever struggled to complete an overly tricky Sudoku puzzle? Fear not as a geeky, fun solution is here. Say hello to the Sudoku Solver!

Hans Andersson, a popular Swedish hacker, has taken a readily available Lego Mindstorms kit and hacked it to solve any Sudoku puzzle it's presented with. The robot starts by scanning the puzzle using a light sensor and after doing the math, begins physically writing down the solution.

If you want to attempt this hack all you will need is a love of Lego, a little technical know-how, and some spare time. The details on how to have your very own puzzle solving robot are expected soon.
