hi Kevin --
I think you missed my point. I accept NXT's limitations. What I'm saying
is, we *can* do the sorts of things I outline, with the platform as given,
if we get enough developers interested in contributing.
I was going to post this anyway, but it's pertinent: Here's a
microcontroller from a vendor I've used on a professional robotics project
(NASA and Carnegie Mellon were the sponsors.) We used one slightly more
expensive, but with similar specifications. This one is particularly
interesting because it has an Arm7, 128kb of flash, and 64kb of SRAM. I
wouldn't be surprised if TLG looked at this when designing NXT:
http://www.newmicros.com/
click on 'tiniARM(tm)' on the left pane.
So, the NXT brick is equivalently powerful to a standard robotics
microcontroller as used in the field today.
What I'm interested in doing is to put together a serious platform, where
the NXT and a powerful PC work in concert to implement advanced robotics
research.
I just wanted to gauge the interest in this sort of thing, that's all.
