Fuel Shooting Census

To be fair, that's a ball every 50 milliseconds. Or two balls every 100 milliseconds, or three balls every 150 milliseconds.

But I doubt that anyone can definitively say they are "90% accurate" until they put it on a moving robot that's driving around on a field, not on some test bed.

Even so, claiming 20 balls per second is a pretty tall claim, even if we allow half of them to miss. Machine Guns apparently have rates of fire of 600-1200 RPM - or 10-20 rounds per second. Teams are apparently claiming to be able to deliver at that same rate!

What have we learned from this poll?

11% are obvious trolls. 23% are very optimistic. 27% probably made the right choice for their team.

That 27% stat seems higher this year.

To me, the more important question is what else are you doing while shooting into the high goal?

In my opinion, the very best teams will have accurate turreted shooters that can shoot into the high goal almost absentmindedly while the robot is placing gears, dumping hoppers, etc. I think robots that have to sit in a very specific spot for a long time to shoot accurately are going to have a harder time than they expect, especially if everyone chooses the same spot right up against the boiler.

The optimism about 10-12 accurate high goals per second is fantastic and I truly hope to see it. However, there are no safe zones, defense will be a thing for sure and I just think high rates + high accuracy are going to be more rare than this thread reflects.

I honestly hope to be proven wrong on that.

Holy?! I guess there are only ~100 voters so far, but 6-10 balls/sec at 90% accuracy would be an amazing prototype. That would have to include an automatic feed and a really good shooter itself with some sort of PID to keep whatever the mechanism is constant over time.

20+ balls/sec 91-100%... how... One hopper is 50 balls and the rest are on the floor. To truly take advantage of that would require a killer intake and killer feeder system. Good luck to whoever is getting those rates, I expect to see you on Einstein.

Also there's no option for 5 balls/sec

FTFY.

I could believe 20+ balls/second for peak feed rate. The poll didn't specify peak rate vs. sustained rate.

I have a hard time believing that teams are going to be capable of shooting 20 balls/sec. From what I seen thus far from other posts as well as my teams protyping, 3 balls/sec with one shooter is pretty fast.

I could imagine there will be teams that get up to 5/sec with one shooter and even if you had 3 shooters you are still only getting 15 balls/sec. I see 20 balls/sec as VERY optimistic. I would guess that most robots will shoot at or under 3 balls/sec for each shooter.

As Jim Zontag would say, teams will tell you what they HOPE to be able to do, not what they ACTUALLY can do. We are still in build week 4, and I will go out on the proverbial limb and say that most poll voters are running on wishful thinking and optimistic projections from their prototypes. Do this poll again after bag day and then compare it with real world performance.

I can't wait to see what comes out in the reveal videos. This is going to be a fun game to watch and play.

Just enough to not slow down our cycles.
