Quite understandable (and understood).

I agree. I wish brickshelf would authorize my photos.
My robot is currently 10in wide, 18in high, and 28
inches long. Not a stick of it was built by anyone but
me with LEGO pieces.

I wish they would, too -- I'd love to see it!

Its not just quick prototyping, but the fact that you
can prototype without the need for bandsaws,
sheetmetal breaks, or handtools that makes LEGO very
impressive.

Agreed.  For structural work -- especially, the sort of tinkery
rapid-prototyping structural work we all love -- LEGO can't be beaten.

However...

I do not believe that there is another building set
capable of building autonomous robots that is as
extensible or useful per dollar per pound anywhere.

It's the extensibility part that's sticking in my craw.  Yes, structurally, LEGO
is very extensible.  But that makes a mechanized gadget, not a robot -- a robot
requires sensors and effectors.  And the RCX limits you to three of each.
That's not very extensible.

Now, if you took something like the OOPic (or similar) controller, and the cheap
and plentiful sensors and effectors that the MarkIII folks have, and used them
to control a LEGO-built robot, it seems to me that you would have the best of
both worlds.

As it is, I'm reluctant to sink $100 or more into a Mindstorms set when I could
spend the same money on a PIC-based platform, and not hit any I/O limits for a
very long time (if ever).

So why am I posting this?  Two reasons: one, I have some hope that LEGO is
listening and will consider beefing up the next-generation RCX; and two, I'd
like to hear about other LEGO robotics projects using PIC controllers.  Though I
suppose that should be a different thread!

Best,
- Joe
