You cannot make a statement as simple as this. There is a torque at which something will give. In this case, the worm gear will probably be the first thing to break. The torque backdriving the motor depends on not just the weight of the robot, but also the radius of the winch. i.e. if the robot weighs 130lb and is directly hanging from a winch of radius of 0.1 feet, you will have 130*0.1 = 13ft*lbs of torque acting on the motor. If someone has some data on these motors, that would be great.
