Double Tube Autonomous

[LeelandS]

Alright Chief Delphi community, this is something that I think needs to be talked about.

We've all seen a hand full of teams include a unique ability into their autonomous: The ability to hang two tubes in autonomous. I first heard of this phenomenon after hearing of the RoboWranglers inplementation of this. I then was able to witness it live during the Pittsburgh regional, from 1114.

I want to know your thoughts on this. How did they do it? What makes it work so precisely? Obviously, the act of hanging those two uber tubes is one that requires both serious speed and precision of control. Did they use a camera? Did they follow lines? What do you think?
