    Hi,

    I am very interested in a project like this! As a matter of fact, we are discussing this in a chess computer forum at www.ismenio.com/forum
    (site: www.chesscomputers.org)

    Do you have a page or a blog with details on this?

    Thanks,

    Ismenio

    Thanks Vikas! I read the article and that was very impressive!
    Congratulations!

    However, I'm looking for one that can play chess and from the article it seems that particular one only play checkers, is that correct or can the program be modified so that it will play chess?

    I have a few robotic models that were available commercially in the 80's and 90's at: www.ismenio.com/chess_computers.html but I'm trying to either build or buy one that has a robotic arm.

    Best regards and thanks everyone for their replies!

    Sorry about that, I had the wrong direct link to the robotic chess models:

    www.ismenio.com/chess_collection.html

    The models are the Phantoms, MB Grandmaster and the Excalibur Mirage.

    Well

    Actually it played chess but the damn thing just kept knocking pieces off here and there ( in chess they are diffrent sized and close together ) But for the final demonstration we needed something which was working perfectly and did not need any human help for playing . So we finally downgraded to checkers ( faroff and similar sized pieces ) .

    Also you need a arm which can have very repeatable motion ( minimal error when repeating positions )

    Hi Vikas

    Could you provide some details of its image recognition...Did you put any spl. markers on the pieces to make them "stand out" for the robot?...the kind special effects guys do in movies

    One more thing....was the AI player embedded or a backend IBM computer?

    Regards

    Default hi

    Well

    Image recognition - IT was simple the system took snapshots of the chess board and broke the board into 64 blocks and compared them between changes . If some block had a more than threshold of diffrence from the previous time meant change had taken place . We did try to use some advanced also's but nothing worked like this simple and effective method .

    The Ai was on an PC ( putting it on 8k of flash is not possible ) You can do something similar for tic tac toe but when you have to do image processing then u require a PC . Also we had some other things which made a PC a must .

    Hi Vikas,

    I was checking around and found this:

    http://www.ideworld.com/fr_index.htm...micon%20Europa

    Could you revisit your project using their idea so as to overcome the problem with the different sizes for the pieces?

    Best,
