| | | (...) 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 (...)

| | | | (...) 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)

| | | | | What about a piece of masonite backed whiteboard that can be purchased at Home Depot, with tape on it and then use whiteboard pens and an eraser? The board would have to be cut to size, and might be way more complicated that you'd like. The nice (...) (18 years ago, 15-Aug-06, to lugnet.org.ca.rtltoronto)

| | | | | 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)
