We have several robots in our lab. Every single one of them has sensors 
to detect where the various moving parts are. Every single one runs a 
calibration routine of varying degrees of slowness when you turn it on 
and/or reset it.

Yes it is. So is a washing machine, or a printer, or any other 
electromechanical device of similar complexity.

My point still stands: The fact that a given mechanism isn't very 
precise doesn't mean that the thing controlling it is inherently imprecise.
