Now there is a ratchet on there preventing you from backdriving (and you can't go forward any more as you're already loaded pretty firm into the field).

Now that's how you lock yourself onto the field.
In 2010, we created a simple ratchet pawl system that worked for our climber. It should release if we at least carry the robot, releasing weight tension.
