Lego Mindstorms robot solves Sudoku puzzles
Swedish hobbyist Hans Andersson has build a robot that can complete a Sudoko grid all by itself, a report in The Escapist has noted.
On his Tilted Twister website, Andersson said that the robot, put together using a Lego Mindstorms kit, first uses an optical scanner to map the empty boxes and grab images of the numbers already entered. The blurry number images are then sharpened and classified using character recognition software, so they can be identified. Finally, the Mindstorms computer calculates the missing digits and writes them in using a pen.
Andersson has posted a video on YouTube of the robot in action..
