Swedish Hacker Builds Sudoku-Solving Lego Robot

This article is over 15 years old and may contain outdated information

Realizing Sudoku is incredibly boring, Swedish hacker Hans Andersson created a robot from a Lego Mindstorms NXT kit to solve the number puzzles for him.

As you can see in the video at right, the robot uses an optical scanner and character recognition software to scan the entire puzzle before crunching the numbers in its superior robo-brain and filling in the remaining blank squares with a pen.

Given that this is really just a writing implement built around a calculator we don’t expect this lil’ guy to go nuts and start lopping off heads or ejecting its pen into people’s eyes.

Then again, that’s what they said about Teddy Ruxpin, and we all know how evil that thing turned out to be.
