    rtl22 working concept —Calum Tsang
   So...after much debate...and some diagrams of how a root canal and partial crown works...the rtlToronto22 working concept is... Tic Tac Toe... ...wait a second...hasn't someone done that before....well yeah. But rtlToronto just can't well leave that (...) (18 years ago, 12-Aug-06, to lugnet.org.ca.rtltoronto)

          Re: rtl22 working concept —Rob Antonishen
      (...) I'd suggest a template that has a very light X and O marked in tiny dots. This would be the "ideal" mark location, and robots (and humans) should try to make them as close as possible top these. -Rob A> (18 years ago, 13-Aug-06, to lugnet.org.ca.rtltoronto)
    
         Re: rtl22 working concept —Chris Magno
     (...) Calum, I think you missed my point. When I said "easier" to draw. I meant to imply, that the robot who plays O would be at a SLIGHT timed disadvantage, vs. the X playing bot.

      (...) So, we find a marker. we agree on 2 games (each bot is and X and an O) we agree that the game board is going to be a 8 1/2 x 11 sheet of paper, with a printed board from a PDF. the bot space is the L shape around the paper. you can have a bot (...)

       (...) I have (yet another) suggestion. This should help people decide where and how to "make their marks", and will help decide if a robot does a bad job of looking for the mark, or a bad job of making a mark.

            Re: rtl22 working concept —Chris Magno
        (...) while the Arbitrator is VERY cool. there is only one. These games are difficult enuff to organize ithout the extra step of hooking up to the Arbitrator. I suggest keep it simple. 2 bot's and a human to time the game. Chris (18 years ago, 14-Aug-06, to lugnet.org.ca.rtltoronto)

      OK, stupid suggestion coming up... Why not print a board that is guaranteed to fit in every printer and then fold (or cut) to that outline? Ralph (18 years ago, 14-Aug-06, to lugnet.org.ca.rtltoronto)
     
          Re: TTT board marks or not —Rob Antonishen
      (...) Not stupid - That is pretty much the same idea as registration marks, but better. The "board" could just be a simple 2x frame that could sit on, or have a folded paper board laying inside. Something like this: (URL) would also give the bots a (...)

          Re: TTT board marks or not —Calum Tsang
      (...) That was my first inclination, to build some sort of registration frame or holes to attach the paper to the robots. That would make sense, but the concern was not to make it too complicated. Calum (18 years ago, 15-Aug-06, to lugnet.org.ca.rtltoronto)

          Re: TTT board marks or not —Derek Raycraft
       I like the 6x6 size. I think the frame is unnecessary. I only need to be aligned with the board, my alignment with the other bot is irrelevant. I can use the alignment marks anyway I see fit. Derek (18 years ago, 15-Aug-06, to lugnet.org.ca.rtltoronto)
      
           Re: TTT board marks or not —Calum Tsang
       (...) I like the 6x6 cell as well. But 1 wide thick lines or 2 wide? I'm not sure the frame is required either, but the alignment marks certainly are. Calum (18 years ago, 15-Aug-06, to lugnet.org.ca.rtltoronto)
      
           Re: TTT board marks or not —Derek Raycraft
       I don't think the line needs to be wide, because you don't need to read it. But one stud wide is plenty wide enough to detect if you think you do. Derek (...) (18 years ago, 15-Aug-06, to lugnet.org.ca.rtltoronto)
      
           Re: TTT board marks or not —Calum Tsang
       (...) The reason why I think we might want two is because of even versus odd spacing. I can't explain it, I just think an odd line space would make it more difficult. Calum (18 years ago, 15-Aug-06, to lugnet.org.ca.rtltoronto)
