| (...) By standard firmware, I assume you mean using the byte codes ala NQC or something similar. If you only want semi-precise timing, you can use the wait opcode to delay for approximately 100 ms between sensor samples. If you want something more (...)

| | Re: NQC floating point library?

| (...) Sorry, the standard RCX firmware doesn't support anything other than signed 16 bit integer math, so NQC doesn't do floating point. Depending upon the problem, you may still be able to convert the operation into appropriate integer math. If you (...) (25 years ago, 15-Aug-99, to lugnet.robotics.rcx.nqc)

Yes, unfortunately the current firmware implementation from LEGO doesn't have a call stack, so you can not build recursive routines. :-( On the other hand I can imagine labyrinths where that bot would never be able to do anything out of them.
