Full Court Shooter!!! (Team 3528 UpNext)

[Jorge Ayala]

Your shooter is amazing, congratulations. How did you do to deal with de vibration and the recoil force?

[Matthew Wang]

Brilliant!

My team is trying to make our shooter almost exactly the same as yours, including the way you stack frisbees and send them to your shooter. However, we are having problems with getting full court shots that are consistent. Our accuracy and consistency varies quite a bit.

Do you have any tips for making our shooter accurate and consistent? Any tips for the frisbee hopper system as well?

Great job by the way!

Looks like stock again just went up on 84 inch robots

I guess we're gonna put some tread along the arc of our shooter....we are doing ok, but not good enough to make full court.

thanks for the video, it's inspiring

What kind of wheel are you using? And what diameter is it?

We are using a 12inch pneumatic wheel. We use 12inches because the frisbee contacts the wheel for a longer period of time. Also, compression is a big part of it. The wheel on ours is fairly flat. It doesn't have much air in it. Therefore, the tire cups the frisbee. We have found the happy medium when compressing the frisbee. If you have to much compression the frisbee will just spit out and not go to far because there is to much friction. If you don't have enough compression, the frisbee won't get that far.

Consistency is hard for sure. We made sure our platform on the curve was slick so the frisbees could slide easily. Also, our curved angle had to be touching the frisbee the same amount of time all the way around the wheel.

The hopper we are still working on. When the bottom frisbee is sitting there waiting to be shot, it is getting sucked in by the wind of the wheel. And when it does that, our frisbee's cup. Also, the whole platform is vibrating, so the frisbee's move a lot. To fix that, we are going to use a pneumatic piston that is vertical and extends on one side of the frisbee, when doing that, it keeps the frisbee in place. When we are ready to shoot, we will pull that piston down and then fire. It then repeats the process.

I hope that helps.

We are using an 8" pneumatic wheel. We have been able to shoot our frisbee far, but not consistently or accurately. Thanks a ton for the info.

Is there anyway for you to describe the amount of compression you're using better? I know it's hard to tell. We think we have found the right amount, but we could be wrong.

What material is your platform made of?

Right. A lot of people are using the 8" pneumatic wheel. I am assuming it is the Andy Mark one?

With the compression, what we did was we built the curved side all around the wheel to measure 11" exactly. This way, the frisbee barley touches the wheel when spinning. Then what we did was we started layering the curved side with material that we though would work. We used double sided sticky tape to mount the layers on the side. On the curves side we had these layers (in order). Metal-sticky tape-black pvc plastic-stick tape-tred.When you do that, it builds up the compression. We also let air out of the wheel a lot. So when the frisbee comes around, it cups the frisbee.

The platform is made out of black pvc plastic.

I hope that helps.

How are you targeting in the video and how will you target during competition?

We didn't target in the video. We just set ourselves up at the right distance.

For the actually game, we will use a camera. I am not exactly sure how to explain all that, but i know we will use the camera to target our distance. Sorry :/

Yes we do have vibration problems. It actually effects our hopper when the frisbees are stored. That is the only problem as of now.

But overall, the vibration isn't to big of a concern. Everything seems to work well.

Is your strategy to shoot full field in every match or is it just something you wanted to be able to do?

We are planning to shoot full field as much as possible. If for some reason we can't, then we will just shoot at the pyramid.

So, effectively, you plan on taking, at maximum, about 6 shots? (Assuming your alliance wants to give you all six colored discs?

I think he means from the pyramid at the high or mid goal still

Oh no no. Sorry I said that wrong. We are not going to shoot at the pyramid itself, we are just going to shoot there so we are in the safe zone. We will be aiming for the 3rd scoring goal.
