Re: Consistent shooter

Speaking of adventures in consistency...

We couldn't for the life of us figure out why we had about a 75% accuracy rate in autonomous mode on the field as opposed to near 100% on the practice field. We controlled for starting position, angle, battery voltage, air pressure, etc. We even added a sizable delay between our "charge" forward and when our catapult fired in order to let the ball fully settle.

One of our four batteries had a terminal lug that was perpendicular to the rest. As a result, the battery power cable protruded *ever so slightly* into the catapult bucket, preventing the ball from seating properly in the bucket. Thus, every few matches (namely when the aforementioned battery was installed), we would miss our auto shot.

Needless to say, the fix was applied the moment we got back and is ready for Mount Vernon this weekend.
