Wow! Jennifer, your work never ceases to amaze me. So much detail, so many complicated sub-systems, so little room for it all! Yet again another great model to marvel about. I'd like to also congratulate you on the excellent presentation you have (...) (23 years ago, 25-Jun-02, to lugnet.robotics)

Excellent explanation, Jennifer (and amazing model too!!!). I just want to note to everyone that LEGO themselves modifies their own parts in their theme parks. In California, they use machined parts and motors from a custom machine shop adjacent to (...) (23 years ago, 25-Jun-02, to lugnet.robotics)

I think we'll probably go with Team Challenge, but I have a slight problem. I'm using MS RIS 2.0 with a serial port. Dacta offers a software upgrade for $30 to 2.5. However, I'm not sure if it will only run off USB. Well, maybe a call to Dacta (...) (23 years ago, 25-Jun-02, to lugnet.robotics)
