Team 4256 Shooting Mechanism

[Kageshini]

A cim 1:1 might have a lot of speed but not a large amount of torque our team is using a simulator to run our shooter same wheel geared for power and is doing pretty good. Do yall have a tight compression?

[Chris is me]

You don't need much torque for a flywheel, the CIM has more than enough.

Looks great, love the bucket hopper.

As chris described, the pneumatic wheel has plenty of mass to result in a big moment of intertia (flywheel effect) as long as it has sufficient rotational energy when the disc contacts it, we are good. The 40' I gave you is a real-life test.

How tight is your compression that you're encountering torque limitations? ...That's a little scary. Are your disks holding up? How did you determine you needed higher torque?

My team is using something very similiar. We really like the radial shooter design.

How do you plan on making the frisbee contact the flywheel? Maybe I'm looking at it wrong but it appears that as soon as the frisbee falls to the bottom of your hopper it contacts the flywheel.

Is there some secondary mechanism that pushes the frisbee into the flywheel? Like an air cylinder or "kicker"?

Anyways looks great!

Great CAD model. One thing I noticed that I don't like: 80-20. That stuff's very heavy. I would advise replacing those cross-members with angle or something. It would be thinner, MUCH lighter, and just as strong.
Other than that, great design!

I second this.

Also, I love that method of keeping the frisbee in line (that is what the lexan on standoffs is for, right?).

We found in testing that a 1:1 CIM is more than adequate (simpler to implement too!)
