What I mean is, will running a motor at low power wear > it out significantly faster than running it at full power? I seriously doubt it's anything to worry about. (If you're curious, the technique it uses to change power levels is pulse-width-modulation). In some ways, I'd expect the opposite - running a motor on low greatly reduces the drain at stall, which means if the mechanism seizes up, and no-one notices for a while, motors running on low won't be at risk of overheating, while motors on full power but unable to turn may run that risk. (The motors have some overheating-prevention features in them, but I figure it's better to not get to that point :-) The flip side of course is that a motor running on low is more likely to stall in the first place, since it has less grunt, so a lesser degree of friction will stall it.
