During my research student days, we had several robotics projects involving
manufacturing and non-manufacturing tasks.  Precision was important in all
applications. Assembly line robotics required precise positioning of the 
manipulator.  Even sensing required precision positioning (as a result of
the sensing).  When we conducted industry sponsored projects, the specifications
put froth by most industries required accuracy (even the tasks demanded this).

For instance, using a manipulator for card assembly, force sensing
and positioning would require the system to be capable of micro-movements.

Surgical applications would most definitely require extreme positioning.

The applications go on and on and on............
