(...) Yes, but I believe that in most cases the CPU for a human has a few more KB of RAM than the RCX. (...) Another difference is the range on visual sensors - eyes can detect lines meters away, and even distinguish 2 lines inthe same field. (25 years ago, 16-Nov-99, to lugnet.robotics)

Greetings All! I am still awaiting the arrival of MindStorms in Hungary, so I have had a lot of time to read the O'Reilly book, lurk on LUGNet and this list for a month or so, and just generally get a feeling for the whole LEGO robotics world. I (...) (25 years ago, 17-Nov-99, to lugnet.robotics)
