A well-behaved motion system depends on motor parameters derived from lab tests. When critical ratings are suspect, run the tests and measure the results yourself.
Nonprofessional digital cameras feature high resolution, innovative user interfaces, customized memory storage systems, and power-saving imaging technology
The problem with most friction models is that they concentrate on dynamic conditions and ignore static friction. The best they might do is include coulombic and viscous friction
