Uh, no, I'm pretty sure it isn't. If the robot is capable of lowering itself without power to six inches after going higher than sixty, then how does it hold itself at the level for scoring? The only way I can think of this being the case is if you had some kind of mechanical device that took 10 whole seconds to disengage a winch's brake, for example.

To answer the OP - worm gears are not the only way to prevent backdriving. They are actually a pretty bad way to do it, as a worm gear that doesn't backdrive is inherently inefficient.

Also, no one said you have to lower your robot with its mechanism to remove it from the tower. If you have a passive hook, just lift it up an inch to take it off and reset your hanger in the pit.
