[Cialug] ROS (Robot Operating System)

Dan,

As far as controlling the S2 with the Chumby goes, I already mentioned that
I'd be tempted to just use serial port communications.

They do have code available for this purpose:

Simple serial:
http://obex.parallax.com/objects/183/

and Full Duplex Serial:
http://obex.parallax.com/objects/54/

It would then be a matter of using one of those libraries to make a (rather
short) program to handshake between the two devices.

Does your S2 really have WiFi?  If it does, well, it's a tough call whether
or not WiFi is the way to go.  I'm just throwing out options.

However you do it, I'd probably keep things simple by having the Chumby
accept a huge 'status word' which describes everything going on with all of
the S2 devices at any time, and then a 'command word' which the Chumby could
yell at the S2 which would tell it what to do with any of its devices at any
time.  That's just a personal preference on how I'd design it.

 I guess that GUI tool for installing the code on the propeller only works
on Windows, but someone (as usual) is developing an IDE for Linux:

Getting serial communications to function on the Chumby will probably be
less involved; it actually is a real computer with an OS.

Also, you mentioned that you installed gcc on the Chumby.  Did you test it
by trying to compile anything yet?

I know this is a lot to throw at you if your not much of a coder.  Heck, I
do programming and it seems like a deep pool to dive into even to me.

Alas, things will always get weird if we set out to do weird things.
