Not sure what you are getting at. Are you asking, are you asking how much torque it would take to backdrive the MiniCIM through the 100:1 Versa Planetary when the robot is disabled?
For example you might be trying to winch your robot up and then not have anything other than the motor's cogging torque to keep the robot from falling?
If this is the case, I urge you to think again. My experience is that without something more than this you will have a difficult time preventing the system from backdriving. It is the kind of thing you can get to work... ...almost but that you'll be sorry about in the end.
It is not that hard to make a latch or a catch that prevents backdriving.
