Yes, I had a detail question which I would not have asked if I did not know this:

Unfortunately, after the mechanicals were done on this, we shifted to doing an active intake, lift, and dumper for tennis balls. One works well (intake), one fairly (dumper), and one poorly (lift, based on velcro gripping the ball). The team was working on this one through yesterday evening; now we're taking two weeks off for the Christmas/New Year holiday, and will come back doing mostly mental and organizational prep for kickoff.
