Robot to automatically wind clocks

Wind up clocks need to be regularly wound to keep the mechanism in good order. If you own a fair number of such clocks, I imagine winding them up could become a chore.

I would guess that winding would be an easy job for a robot, particularly if permanently connected (perhaps via a rubber grip) in an asthetically neutral manner. The robot may need a few sensors: to prevent overwinding (measuring torque); and to rewind at the right time (perhaps measuring the vibrations of each tick and determining when the mechanism is loosing power - or more simply, just rewinding after a set period of time).

It may be best to house both the clock and the robot in an asthetically neutral glass case.
