Hi there, I am just wondering - Snaptrax, the Spybotics tracked thing looks like it has longer rubber treads than treads included in RIS. Is it true or not? I tried to build treads with similar design and it looks like there's much more friction (...) (23 years ago, 5-Jan-03, to lugnet.robotics)

(...) I know that this won't help, but I tried your program (and the lnptest.c program from the lnp distribution) and got the same errors. No message came through, only frame errors. Will have a closer look at this. Regards, Michael (23 years ago, 5-Jan-03, to lugnet.robotics.rcx.legos)
