Frc shooter improvements

I have a shooter,the shooter intakes using small 3 in compliant wheels, two row of them, that vector the ring up. these compliant wheels are driven by neo 550s, and there are no gaps in them. The shooter/outtake for this system is run by two full size neos, and has four colson wheels that shoot from the top and bottom. the wheels are spaced so that they are along the side parts of the ring. how could i make this type of shooter shoot faster? i am looking for mechanical changes

Immediate thoughts:

  • Use a different motor for the shooter
  • Use a smaller gear ratio on the shooter motors
  • Use more compression on the note

Have you had issues with getting it into the speaker?

Also, do you have a CAD/picture of the bot?

If your ring can touch both the intake wheels and shooter wheels at the same time make sure both sets of wheels are going about the same fast linear speed.

We have a similar setup (a double row of 2" wheels with a Falcon 500 and a double row of 4" wheels with a Falcon 500). At full speed it can shoot past the target to about the parking lot. Look out judges!

I’ll get pictures up in a little while, but would we want to put a bigger gear on the shaft or the motor?

ok, but one is run by full size motors and one is run by smaller ones? idk how i could make them be similar speeds

Using your gear ratios and belt drive ratios and the circumference = diameter times Pi of your wheels you calculate how many meters per second your wheel surfaces are going. Use motors’ rpm’s that gave the same linear speed for the two sets of wheels.

idk if you can watch this, but this is our shooter

ohhh that makes sense, thanks! im just trying to make any improvements i can

also, whats the spacing for your 4" wheels?

I don’t know the exact distance and the rings are squeezed quite a bit. Nothing gentle about this mechanism. We have more wheels for a lot of squeezing at all positions of the ring in the shooter.

This reads like a chat gpt prompt vs a CD question…

So true! I wonder if the OP knows that CD is comprised of people vs being a large language model. Thinking more, I wonder if we would know if any CD “users” WERE large language models…

The design of your shooter is consistent with many, many designs being discussed on this forum. There are tons of posts describing wheel speed, note compression, wheel diameter, number of shooter axles, position of wheels on the axles, and more.

It looks like you are using 4 inch shooter wheels. Running these with a 1:1 ratio from a NEO is going to get you all the Note exit velocity you are likely to want. You probably will want to run the NEOs at less than 100% output for most or all shots.

Note compression of 0.5" seems to work well for many teams with this design. Somewhat more or less is certainly possible, though.

We have been using 1’’ compression and it has worked very well. We have the same top-bottom shooter as seemingly everyone else, and we’ve done tons of testing.

Stiffness stiffness stiffness. Shooters are incredibly sensitive to a lack of stiffness because even small angular deflections can cause shots to go off. I would make the swap to aluminum plates if possible,

I was wondering what fractured the translation to English and maybe it isn’t how people from Ohio talk.

maybe it was a chatgpt prompt, or maybe im just built different
