I'm proud to add team 548 to the list of teams who successfully navigated the Y and posted uber tubes on the top rack in autonomous. We actually exclusively used this mode at our Ann Arbor district on Saturday to test its reliability. Unfortunately during elimination rounds one of our four motors broke and we could no longer navigate the Y - no worries, we followed the line straight and hung the uber tube successfully during our last match.
We follow the line using line sensors and have found the algorithm, once perfected, to be quite reliable. We measure distances using the average of the encoders on left/right motors. We're looking forward to using our autonomous modes to our advantage at the Michigan State tournament and (hopefully) at championships!
Videos will be up soon.
The weight sounds about right, too. If you need more than 65 pounds for your manipulator, then the drivetrain isn't the part you should be redesigning... - s_forbes [more]
