(...) OK, that's definitely a good reason to keep things simple. I'm far from convinced that _any_ sensor suite (advanced or not) will completely fix the drift problem, but if the sensors themselves return absolute coordinates (or even absolute (...) (22 years ago, 10-Nov-03, to lugnet.robotics)

(...) Or, then again, you might not. As with the vast majority of the ROM subroutines (and all the _Bead subroutines) this subroutine fiddles around with a global variable (via calls to EnterBead and ExitBead). In this case it happens to be global (...) (22 years ago, 10-Nov-03, to lugnet.robotics.spybotics)

I had to buy this set just to see. Total disappointment :( Nice idea, dreadful implementation. The motor/battery box clearly tries to record the rotation of each of two wheels in "record" mode, and I think it actually manages to do that part ok. The (...)
