Consistent shooter

[Johnnybukkel]

Our robot doesn't fit any of the shooter catagories... We are very consistent in the high goal (when our pit checks are done right).

Your category of shooter is Scary.

Nah, Howie's great! Definitely a robot that the kids can play with.

Quoted for truth. And spotlighted.
See you guys tomorrow!
#repeat?

At the LA Regional, our pneumatic catapult shooter had a 100% scoring percentage in both autonomous and teleop from our 2nd through 10th qual round and had 1 miss in elims amongst heavy defense (scored 6 in elims QF).
Note in the first round we missed shots due to a pneumatics leak which was fixed shortly after.

I was impressed with how consistent our shooter ended up performing.

We shoot between 6-8 feet away when stopped, and 8-10 feet while in motion (we use sensors, indicator LED lights, and telemetry to determine shot attempt distance)

Uhh... So how exactly does it work?

It's a giant, super-scary powerful slingshot-thing.
Basically it could probably shoot from one field to another at championships. Legitimately.

Well, to be honest, we can only shoot 19 feet... Vertically...
And #Repeat is possible.

Man this took me a long time to get any solid data on our team doing anything related to this until today (so sorry for the wait). As of today we did scrims with another team who had 2 balls. One was under inflated and one was reasonably inflated. The level of inflation had a major impact on the distance we got out of it. Other then that everything else was consistent we generally just lose distance as we lose compression on the ball. Now that I think about it I might see if it is within the rules to let our arm driver feel how inflated the balls are pre match to see how to compensate for aim...

Right with ironicdeadbird on this one. The under inflated one was VERY underinflated, and was actually a yoga ball from Target inside the official cover. sitting on it compressed it to 1/2 diameter. Shots were about 1/2 normal distance. We've been practicing lately with an overinflated ball similar to what we found on the field in Utah so that our shooter would be set up to handle it.

Just to be sure I'm reading this correctly: are you saying that the underinflated ball IronicDeadBird used for his testing is the "very underinflated" one with a Target yoga ball inside?

If so, does anyone have any test results with an "official" "regulation" ball that is somewhat (but not "very") underinflated?

[mrnoble]

Ironicdeadbird is one of the mentors on my team, and we're talking about the same ball. A little more background:

Prior to Utah, we practiced with a ball that we deemed properly inflated. In Utah, the balls were slightly more inflated than we assumed they would be, and they became tighter as the event went on, so they seemed "overinflated" to me. Since returning, we've inflated our ball more to simulate field conditions. Yesterday we played with two balls that were not ours: one was very slightly under what we had been using prior to Utah, the other was the aforementioned yoga ball.

We shot from specific points on the field yesterday that we had previously tested. The distances were similar for the ball with "normal" inflation and very short with the other ball. Consistency is very hard to measure with our design, however, as ball shape, location in the shooter, and battery charge all effect it as well.
