Tic-Tac-Toe-Playing LEGO Robot

Posted by ryuzaki0 on from the step-right-up dept.

David Primo writes "TechEBlog has an interesting article on a Tic-Tac-Toe-playing LEGO robot named WOPR — created by Bryan Bonahoom. It uses built-in sensors and a custom program to challenge humans. Video included. From the article: 'The NXT display also enables the inclusion of instructions to the user on resetting the robot. This allowed WOPR to run unattended.'"

    Um, I think the guy realised that when he called the robot WOPR Would you like to play a game?

    A bunch of MIT students created a tic-tac-toe playing computer a LONG time ago, out of *Tinker Toys*.

    I know it was a long time ago, because:
    a) I saw it in the Boston Computer Museum in 1991 and it had been "broken for years"
    b) Nobody plays with Tinkey Toys anymore... And hasn't since about 1975.

    Ah, here's a neat article from Sci Am in 1989 (probably the one I read which caused me to seek it out in 1991): http://www.rci.rutgers.edu/~cfs/472_html/Intro/Tin kertoyComputer/TinkerToy.html

    For the impatient, there is a photo on the last page.

  4. tic tac toe vs. connect 4? by Main+Gauche · · Score: 2, Informative

    Haven't folks already programmed LEGO bots to play connect four? Some can even beat kids who play against them.

    OTOH tic tac toe has almost no complexity, so what's the big deal?
