I'm sorry, but I find this VERY funny. :) But you've already said how little
you really know about building, so I guess it's OK.
A robot that could copy a continuous model is something that would be very
do-able.
On the other hand, if you allow gaps, it would be very easy to make a model
that's almost impossible for a robot to copy. For example, an M where the
middle leg doesn't touch the bottom line:
studs: 1 2 3 4 5 6 7 8

Also, it's going to be hard for any type of sensor (light sensor or camera) to
tell the difference between a brick of unknown color, and the background, unless
you have stereo vision (two cameras).
Once someone can make the "easy" one, then maybe you could make it harder...
