2386 prototype shooter

I like it but does it only have a single degree for aiming?

Nope! Still have a few cards on my chest!

There are CIM-ulators and CIM-Sim gear boxes that allow you to use a "5th CIM" but it's just a rs-775 or a FP with a gear box. It does give you the same output RPMs of a regular CIM.

You are correct! Run a 775 at a 2.7:1 ratio and bam! Cim-u-lation.

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.

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?

^ This.

Because, am I seeing correctly that you are driving the wheels directly off the CIM? Certainly not totally ridiculous, but I would expect it to have a little more trouble accelerating the ball than is observed.

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.

Nice job.

With a longer ball path, you can put more backspin (or topspin if you have an inverted shooter) on the ball. Simpler than software!

Nice shot

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

Definitely a nice start! How far was that?

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

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

Nice job.

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

A good 30 something feet.

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.

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