Don't know anything about your design but keep in mind that if your robot turns sideways on it's way up, your "height" is now your frame perimeter extension and it can't exceed 15 inches. If you have a low bar robot that's climbing with a winch you will most likely need a dedicated solution to staying level when you climb.

If your team has already considered this and designed around it, I apologize for wasting your time.
