Try putting some bricks together using your knuckles - that is with
pressure feedback, now try doing it in a dark room :) It's a cute idea
but I think you'd have *real* trouble with anything smaller than 2x2
bricks, or is that what you meant?
It probably isn't impossible.. but I'd imagine that you'd need:
* vision/pattern matching to resolution were it could distinguish 3x1x2
plates from a 1x2 brick
* A variety of manipulators: pressure-feedback gripper, poker/puller,
seperator etc
* Layered construction? Would require determining what order to build
sections in.
I think that is a few levels beyond even a few RCXs at present.. maybe
in a year or so some of these problems will have been solved?
But then it depends on what sort of assembler you mean - making a 2x4
brick wall is obviously simpler than getting it to build your SuperCar!

I like that idea! If they competed for bits of Lego by wandering about,
picking some up and putting it in their 'area' then that would be quite
fun. You'd need some electronic scale and the one with the heaviest pile
of Lego would win :)
Or you could give each robot a color or type of piece for which they get
extra points for, but with the scale you could have automatic
score-feedback.
You can hold the data for many complex genetic algorithms in 32k, so
they could time share or something - it seems wasteful having one GA per
RCX.
