If anyone is wanting them, I'm still seeing RIS 1.0 systems with the 'upgrade to 1.5' sticker on them at most the local Best Buys in NE Kansas (IE Topeka and Overland Park Areas) Tom (25 years ago, 13-Dec-99, to lugnet.robotics.rcx.nqc)

(...) Sorry, should have said the command console, which does use the VB stuff, and also (of course), sending anything yourself from VB... (25 years ago, 12-Dec-99, to lugnet.robotics.rcx.nqc)

(...) That's not true. Neither NQC nor LegOS require any vbx files. (25 years ago, 12-Dec-99, to lugnet.robotics.rcx.nqc)

Dave, I like the idea of teaching how to solve certain problems both with multiple threads and with a Finite State Machine. Adding "switch" would be great! Personally I think that a plain 'C' FSM using switch can be made to look very clear if (...) (25 years ago, 12-Dec-99, to lugnet.robotics.rcx.nqc)

(...) The problem is that 1.5, does not have the vbx file to allow these to work. You have to get this from a version 1 system. (...) 1.5, adds quite a few useful pieces, but loses a few others. Having '1' upgraded, gives you the best of both (...) (25 years ago, 11-Dec-99, to lugnet.robotics.rcx.nqc)

(...) [snip] (...) FSMs are a boon in our behavioural robotics projects. If you have read the Rod Brooks papers, he uses them to implement subsumptive architectures in his "radical" robots. I have used them a LOT in my Stamp II robots as the only (...) (25 years ago, 11-Dec-99, to lugnet.robotics.rcx.nqc)

(...) Adding a switch statement to NQC would certainly help make implementation easier...I'll see if I can work it into the next release. Actually, I've been somewhat surprised by the general lack of needing FSMs in my own Mindstorms programming. I (...) (25 years ago, 11-Dec-99, to lugnet.robotics.rcx.nqc)

Vlad, The Finite State Machine is a good subject for people to consider in robotics, especially in coding the typical 'looping forever' Rcx applications. Lots of regular 'C' FSM's are implemented with a State variable and "switch" statements, or (...) (25 years ago, 11-Dec-99, to lugnet.robotics.rcx.nqc)

(...) thank you (and bob fay) for your two responses. i have a sneaking suspicion that bob was right on with the curious battery problem. i opened my tower battery case and "re-seated" the battery. (and i confirmed it *was* in the proper (...) (25 years ago, 9-Dec-99, to lugnet.robotics.rcx.nqc)

(...) Try this: nqc -v -raw 10 and then also this (substituting the right filename) nqc -v -firmware <filename> and post the results. The "-v" option turns on some logging that may help us figure out what is wrong. (...) The firmware file is (...) (25 years ago, 9-Dec-99, to lugnet.robotics.rcx.nqc)
