We will use winch motors that can backdrive (Fischer Price) and will need a device to prevent backdriving as well. Has anybody come up with an elegantly simple way to accomplish this? We would like it to be a passive device, similar to the clutch in a manual window regulator mechanism.
We'd rather not have to use a cylinder/blocker device because of the weight. Has anybody had experience using an electrically actuated servo to move a latch pawl or something like that?[/quote]
whats wrong with a spring loaded pawl? Just look at the hand power winches they well at home depot. As mentioned above you could easily fabricate something like his with tools as simple as a a bandsaw.
