| (...) From something I read 12 years ago for my university project (a Lego robot of course, but pre-RCX), I think it required differential equations (ugh!). Probably a bit too memory-hungry for an RCX. Perhaps you could use the PC's computing power (...) (21 years ago, 26-May-05, to lugnet.robotics.rcx.legos)
