While I know a few other people have done this before (even though I can't find anything online!), this is new to me. But I thought I'd give it a go anyway. This is my first attempt at doing a "pole-balancing" robot. It's hard! Suposedly there are (...) (23 years ago, 20-Jun-02, to lugnet.org.ca.rtltoronto, lugnet.robotics)

About the most economical way to install a compass is the Dinsmore analog unit. It has two analog outputs which you will need to do some serious processing on, they aren't sin and cos, so you have to do a sort of arctan and then lookup table (...) (23 years ago, 19-Jun-02, to lugnet.robotics)

(...) Derek, what you need to assess is how stable you need a reading (I guess you want an heading). A compass needs a stable platform to provide you with a decent value. Any acceleration (turning is a kind of acceleration) is going to spoil you (...) (23 years ago, 19-Jun-02, to lugnet.robotics)

Yes, very odd. After I signed in and copied the link, I got to the NQC file. Thanks. I'm using NScape 4.76. Never recall having that happen before. I'm surprised they don't have an errata on the book. I've noted at least 5-6 obvious errors in the (...) (23 years ago, 19-Jun-02, to lugnet.robotics)

I'm just getting into MS RIS 2.0 and started looking at some of the suggested code for line following. It's generally clear, but it looks like it's best used when a robot is placed parallel to the start of a line and on the line. I'll probably build (...) (23 years ago, 19-Jun-02, to lugnet.robotics)

What exactly needs to be done to 'upgrade' DJGPP to work with the new LegOS? Are these same changes required for cygwin?
