Congratulations (again) on your win, Rex. You have an excellent bot and team.

A few things I observed in the regional:
- The rumors I heard of people at FIRST painting the soccer balls to make any ball finding algorithms fail is untrue, from what I saw. All balls used were pearl white.
- The supplied target-finding algorithm wasn't the best that could be used. It picked up the target often, but there were times where it got locked on to an arbitrary object. Putting a threshold at the end helped a bit in recognition. (see: If target.score <= 1000, discard it.) [[Note: This should be done *after* the concentric ellipse testing, as it is impossible to get 1000+ for a single ellipse.]]
- Kicking, unless you have a really soft (8- ft) kicker, in the offensive zone didn't work well; we- and many others- ended up ramming the goal to push the ball in.
- Midfield shots were not too uncommon.
- The camera stream was either REALLY laggy or nonexistent for quite a few matches
- If you lose ANYTHING during a competition (see: an omni-wheel
), you will be penalized one point unless your robot is disabled immediately after for "intentional detachment of parts". - Autonomous: We had our balls set up like:
G
XXO
XOX
OXX
R
R: Robot
X: Spot
O: Ball
G: Goal
and turning tapped a few out of the way. In addition, if we set up our balls in the same column, the one that we kicked first was liable to hit the second/third ones. So, for midfield/defensive autonomouses, consider your ball placements. - A solid near-field/offensive field autonomous with a kick in it can be used for all three fields easily, and is really helpful in most cases.
- Connecting with the field this year is *extremely* easy and quick.
- The max score of the day, I was told, was 9-0.
- The autonomous of "go forward for one second, kick", when used in the offensive zone, gave us a quick point.
- Kicking from midfield sometimes resulted in hitting the small bump that leads up to the goal, and the chain above the goal. Both prevented the ball from going in to said goal.
Thanks for the excellent competition, everyone. It was definitely the most fun I've had in a long time.
Sadly, our FRC team won't be attending worlds this year. So, I wish you all the best of luck in getting to- and in winning- the championship.
