I'm not an AI expert, so correct me if I'm wrong.
To evolve, you need a purpose and some means to give it a score how it performs in real life.
It would evolve into what? It needs a purpose. And why should it evolve in the first place?
How would you say that "no, this design is no good". Grab the best of this design and try to combine it with the best of previous designs, adding some random data (I believe this is called Genetic Algorithms).
And so on, and so on...
I think you should start by creating some sort of mechanical hand that can grab a part, rotate it if needed and fit it with precision in some place.
It also needs some strength and programming to "understand" how the parts fit and why they sometimes don't fit. [...]
Yeah, that's definitely the ultimate project. :-)

| I'm not sure how feasible this would be, but has anyone considered making a digital camera using the light sensor? All you'd need is a focusing mechanism with lenses/mirrors, and a couple of motors to scan left to right and up and down. Sounds easy (...) (25 years ago, 9-Feb-99, to lugnet.robotics)
