Nice images, they should go nicely with your excellent site. I am curious as to the ground that is in those images. Looks like broken gravel with grass or some other green growing through. I am wondering if this is your back yard, or drive way, or (...) (24 years ago, 8-Apr-01, to lugnet.robotics)

Hello to All, I don't have a LEGO MindStorm Robot to play with yet :>(, but I've been doing a lot of research trying to learn the various techniques used to program the RCX. Do any of you use or plan to use Java to develop your RCX programs? I could (...) (24 years ago, 8-Apr-01, to lugnet.robotics)

(...) There certainly is some kind of a Java implementation for RCX. I havn't used it though...most people start off with NQC (Not Quite C) which is a very good starting point...then if you need more, dump the RCX firmware and replace it with (...) (24 years ago, 9-Apr-01, to lugnet.robotics)

Steve, Thanks for the reply. I was thinking more along the lines of abstraction and simplification versus a pure visual language. Something that would make programming an RCX alot easier with respect to range checking for valid values, such as motor (...) (24 years ago, 9-Apr-01, to lugnet.robotics)

(...) Ah - OK. (...) I think that might just be overkill for a system as simple as the RCX. There are only three motor outputs - and you have no direct control over speed or angles - you can only say "forwards", "reverse", "brake" or "freewheel" (...) (24 years ago, 9-Apr-01, to lugnet.robotics)
