Sure. But that does not automatically lead to good results. I think you
can be able to mimic the internals of a robot with some precision. Ah,
you will limit your robot to some drive-and-seek robot, I think? I mean,
you don't want to simulate a chess playing robot?
Even if you can handle the robot's internals, you will get problems if
you try to get the same results "in real life". Your carpet gives other
friction, your wooden floor has some cracks your robot will follow a bit
and so on. I played with simulators for a while and they can help to
understand how to program the robot. But on the other hand, that is what
I build my Lego robot for...

Right! Any success stories are welcome :)
