I agree whole-heartedly.
This is the idea behind JCX which has now been in development for over a
year, and has been rather extensively alpha-tested at a major university.
This past fall students at the University of Utah were able to use the
CMUCam vision sensor and build *autonomous* (no PC with the camera on it!)
robots:

We are finally into the move to production on JCX. (If the economy were
better we'd have been done a year ago.) A JStamp CPU board for JCX is being
prototyped this week and work on the RFModem is crawling along.
The point of this message is not only a shameless plug for JCX vaporware
(it's really coming this spring) but to sound an upbeat note that there
will soon be practical alternatives to the RCX for "real, serious" robots
using the Lego mechanicals and sensors and motors (also those of HiTechnic
and other companies).
We plan to sell some kit of JCX sufficient for initial work for about
US$500, which is a fraction of competitive robot products.
Last year an engineer from Lego in Denmark contacted me and we are planning
a product swap and further dialog, so, at some level, Lego is aware of and
interested in JCX. Perhaps Dacta or whomever will pick up JCX once it
becomes "real" and is shipping.
I realize for the purists this is not an answer simply because Systronix is
not located in Denmark and is not part of the Lego group. But if all you
want is a viable, powerful, expandable, open system...
There is also a new 'Embedlet' SourceForge project:
http://sourceforge.net/projects/embedlets/
which touches on the issue of creating firmware and hardware modules which
could easily plug together for variety of applications including robotics.
It's all Java and open standards based, and there is a very active mail
list. And - it's Open Source. (I'm blind copying the embedlets list with
this message). There are some university-level educators active in this
project, too.
So I am very optimistic about the future of Lego robotics! By this summer
there should be a whole raft of interesting new technology available.
