Re: 2386 prototype shooter

Definitely a nice start! How far was that?

I'm kind of curious what the weight of that flywheel is. That is some impressive distance. I really like the simplicity of this prototype.

Nice eye! Its just an aluminum disk, no real measurements thus far.

My question(s) how long does that take to spin up?
And how many balls can you feed though it before it slows down significantly?

It takes around 3 seconds, and you can feed at least three with the same trajectory (haven't been able to test more!).

I think you'll notice a bit of an erratic spin difference between different launch speeds with the static bar. My team is doing something similar, but with two sets of wheels, one on the top and one on the bottom so we can control spin if needed.

Nice job.

The problem with two sets is the inconsistency in speed/entry for the balls entering the shooter.

A good 30 something feet.

Re: 2386 prototype shooter

Why is there a fly wheel on there and what does it do?

Its used to maintain wheel speed when a ball comes in contact with the launching wheel.

How is the CIM connected to the axel the wheels spin on and how is the axel connected to the wheels?

A whole lotta set screws.

Re: 2386 prototype shooter

Oooh, set screws are evil! Embrace the spring pin...

Re: 2386 prototype shooter

Update!

Time to get rid of the SIM, shame you can only have 4..
New custom transmission with a RS-775:

Just a first run gearbox, the final one will be lighter and look pretty.

In terms of the cim-u-lation, wouldn't torque play a factor, because those motors, even with the gearbox, have a nominal amount of torque

The Cim-U-lator that we made is a 3.33:1 ratio and actually gives us a torque rating of 375 oz-in compared to the cim of 344oz-in. So its actually pretty close to the CIM itself.

Your right my mistake. The numbers are off then.

Also if anybody would like the cad drawings for the gearbox let me know and il send it to you.
