Ball bouncing out of the high Goal

In this case, the refs called a field error, stopped the match and worked on the chains before restarting the match.

Not quite - a boulder got stuck on swinging chains in the high goal. From my vantage point at the scoring table, it looked like a couple of the chains swung together and almost cradled the boulder by wrapping around it - either way, it was pretty stuck. A field resetter tried to dislodge the boulder with a pole, but unfortunately the boulder fell back into the field, requiring the match to be stopped.

My concern would be what would be the ruling if we shot the ball into the high goal, but there was so much force on the ball that it bounced off the backboard and rebounded back into the field. Would that still count as a score or would we have to shoot it back into the goal again?

Yes, they only count a boulder if it falls down the tower and passes through the sensors before rolling into the corral. The chains do stop almost all of the boulders from bouncing out, but there are times when I have seen a boulder launched into the high goal when the bot isn't quite square with the goal, and the ball will pass in one and out the other, and I have also scene a boulder bounce back out off of the chains. This happened to our bot maybe twice at the Northern Lights Regional. I don't think it has so much to do with the power of the launcher, as it does just plain bad luck.

+1 this. While reducing strength will help, it'd be very hard to develop a way that completely eliminates the possibility of boulders falling out. Our shooter this year was fairly weak yet we had a few problems with balls bouncing out of the high goal. A boulder bouncing out of the high goal in this match costed us the quarterfinals.

I have lost count of how many balls we have had pop out. Still less than a dozen overall though I think. We do have a fairly strong shot. I think you just shrug and focus on getting those points back. I don't really think it is something that the GDC can completely eliminate. The chains certainly help. Most of the time I think, as someone mentioned, our shots just rolled across the back and out.

The boulder has to stay in the goal to count for points, and exit through the corral.

In your example. The basketball never entirely goes below the rim. So that's an easy one. The more I think about my Jagbots. The degree of difficulty shot is rated at 4.6. So they should have gotten 46 points for great effort. Thank you so very much. Thomas (just give me a crabcake) McCubbin

In your example, the ball never passed the scoring apparatus on its way to the corral. So it was never scored.

We just don't shoot such that our (nearly 45 mph velocity) shot trajectory is perpendicular to the back board and we've stopped having bounce outs. Every shot that we took that went into the high goal at our state championship event stayed in.

This isn't just a FIRST lesson, it's a life lesson. A lot of times you just have to play with the cards you've been dealt and do your best despite unanticipated challenges.
