Impossible?

I think it's far from impossible.
Take a look at what is needed:
A rotary motion device to turn counterclockwise (assuming that is the direction to lower).
A method to line up to a target.
An end-effector of same shape is device needing turned.

I think we've done things harder. Maybe not so much as precise.. but hey, we made things that balanced on a teeter totter just fine.

I also think that it could be a neat strategy.

Consider the rule stating to be hanging you must be fully supported by the bar. It doesn't say "the highest piece of your robot must be at a height of 10' relative to the carpet. If team X can lower the bar, then it would stop any Low-Hanging teams from getting points. (such as the teams which intend to only hang 1-12" from the ground).

Relax on the bashing. Let them update if they need to. It's a valid point.
