It's easy to forget in the excitement of your first build that your robot is likely to get the living crapola rammed out of it during games. We ram ours into walls, flip it over onto its sides, tug on cables... I suggest that, as soon as you have it working, you do the same -- and then fix whatever no longer works, and then do it again, and again, and again, until 2-5 times in a row there's nothing to fix.

Consider some kind of funneling system from your ball pickup, if you haven't already. The dual rails help a great deal, and one belt might be sufficient -- three-point centering is older than Newton! (The scientist and the field).

Yup. That's true with everyone. Your 'sweet spot' technique is a good one, to be sure!

We made our own from surgical tubing, 12 gauge wire, and superglue.
