Dog Gear?

Simbotics used a Dewalt transmission that does not backdrive, so they don't need to power the motor to hold it in place (this is important because you don't want to put power to the motor when the motor isn't moving). The Supershifters and the Gen 2 can backdrive, so you would need to further modify them so they don't backdrive if you wanted to do a winch like Simbotics did.

Really? I was thinking more of the opposite, as where you would want a motor that has the capability to be free spinning when the dog gear is not in contact and thus the cable system frees it self. Can you give me any further details about this? My first thought was to use one of the window motors and then second thought was a fisher price.

Sorry I meant that does not backdrive when it's in gear, so it can hold the winch in place. When you shift the gearbox into neutral, it will have to go the opposite way, to unwind.
