Ruby & Robotics?

Hello all,
Does anybody know if there are any good implementations of Ruby in basic
robotics? I want to learn some robotics (basic ground-level stuff, i.e. how
to control servos from a computer with ruby) and I don't really want to do
it in Java when I know Ruby and love it so much :). Also, anybody know a
good place to start for getting into that kind of stuff?

Thanks,
Mike

This is something related I came across before. Though as much as I
like Ruby, it's not really the right tool for the job.

In general, no, but at a RubyConf a few years ago (2003, I guess),
Shashank Date showed off controlling a Lego Mindstorms assembly using Ruby.

If you google a bit you'll find more links about Ruby and Mindstorms

If you already have a java api to your hardware controller, you can
write your program in jruby and use the java calls

Actually, real robotic systems need to be real-time systems, running on
Real-time operating systems such as the Linux + Xenomai real-time extension
patch. But, for testing certain alghoritms, I think ruby could act as
Matlab, for prototyping. But you need to have in mind that you will need to
port the final alghoritm to C ou C++, since, usually, real-time system APIs
are written in those languages...

Writing realtime systems in languages such as Ruby or Java (both have
garbage collector) is not reliably (actually it is impossible in Ruby,
currently, as far as I know).

Good luck!

Rodrigo.
