The two kits - Dark Side and Droid - are good from a "wow - cool Star Wars
models" perspective. They suck big time when it comes to using the
micro-scout for anything else. I built the BattleDroid from the instructions
on the Lego web site and then modeled it with MCLAD/POV. These are really
cool tools. It takes a while to get a complete model drawn - I think I spent
about three weeks in total - an hour here and there - but the end result was
worth it.

As for the RIS - turning/position seems to be the hottest topic on the
robotics newsgroup. I am currently working on getting a handheld GPS to
determine the position and then send the robot away to do certain things,
and head back to where it started. When I have anything serious to show,
I'll add it to the web-site.

I have noticed some posts using rotation sensors to determine
position/rotation - have you tried these? Also, some interesting gearing
mechanisms. As for not using tracks - hmmm - not too sure about that. The
Mars exploration kit comes with some big wheels - I think...

I'm from Cork and have the Mindstorms RIS kit and the R2D2 kit - what a blast.
I have been watching LUGNET for a while now and have tinkered with MCLAD,
L3P, POV-Ray, etc. I even built and modelled the BattleDroid. Check out:

Hey - That's cool! I've been slowly learning MLCAD and only recently started
to model things entirely virtually. I'll fire a few up onto BrickShelf one
day... Is the R2D2 kit any good? I'd avoided it and the Dark Side kit 'cos
they looked more for kids. Actually now that I've said that it makes no
sense. I mean, theoretically most Lego is for kids, right? Argh.

Mindstorms question for you (and anyone else) - Have you ever built any kind
of mobile robot that *doesn't* work on treads that turns properly on carpet?
I've been trying to do that for a while... I had a robot on the big wheels
you get with the RIS (1.0) which had a seperate rack and pinion steering
mechanism, but even on the lowest speed setting for the motor the stress of
turning the wheels broke the mechanism after a couple of three point turns :(

Smiths in Cork would be my only source, apart from Shop@home.

Aha! So there *are* Smythseseses outside Dublin!

Nick.
