Viscous friction, like drag in a fluid? I don't think many robots use systems where this would be a big concern. If you have oil-bath lubrication, or some fancy hydraulic coupling, this might factor in, but it's most likely safe to neglect for our robots. Perhaps you mean friction between wet or dry surfaces?
