Accuracy is always a problem and defining your error threshold is part of
the design process. However, if the mouse's optical counter is attached to
a non-drive wheel the accuracy can be acceptable.
There used to be a book posted on the net that covered robot navigation
issues very thoroughly. I believe is was done by one of the authors of
"Mobile Robotics". The section on dead reakoning covers many of the issues.
The mouse rotation counter is essentially a part of a dead reakoning system
and hence has all its benefits and flaws.
