I have two questions that I just want to make sure you have thought of (It seems you probably have)

How well does your feeder work when you have bumpers between you and the wall? You might need something to fill the gap.

What are your overall frame dimensions? I know it's a prototype, but it feels a tad big to me.

Keep up the awesome work! I wish we were already driving around.
Thanks for your questions!!

We tested with bumpers. Video evidence is being uploaded now. Will PM you when finished.

You caught us!! (Are you a wizard?) Hahah. Anyway, our prototype robot is a tad wider than it should be (~ 2"). It will be rectified on our final robot. We just didn't worry when making the prototype. Thank you for making sure!!

Brilliant idea on the 5gal bucket ramp and aluminum. What's the fastest speed you can load frisbees into your system and not drop any?
Also a pretty slick hanging mechanism - I like how it's integrated seamlessly into the rest of the robot.
Final question - are you still running 2wd? If so then might I suggest that you look into adding the other two CIMs?
Yes, we were using a 3 way solenoid valve. Not sure on legality of that so we subbed out a 2 way solenoid valve and tried that. It still worked.

We have not tested the speed with which we can enter frisbees. Will test that tomorrow. Thanks for the advice!!

We have a Technical College across the parking lot from our high school (so lucky!!! We know...). That cylinder is from their program. We ordered a similar cylinder from Bimba for our final robot. It's a little skinny but with the same stroke.

We are running 2wd. Each Cimple Box has 2 CIMs in it (so 4 total on DT).

Thank you so much for your questions and advice!!

I just went to Lowe's and bought two 5 gallon buckets.

Steal from the best, invent the rest. :)

Thanks for the great idea! Good luck and huge congrats on getting a prototype robot done in such short time!

If the new cylinder doesn't have enough force you can easily add Constant Force Springs to assist it.

Thank you so much to everyone for all of the advice and comments!

We took them to heart and made a video with some of our new tests.
Prototype Shooter - Responding to Comments

We also recorded a FULL ROBOT DEMO (auto, teleop, and hang) with no editing so feel free to check that out too!!

Prototype Robot - Full Demo

We'll keep updating our YouTube and Blog throughout our Final Robot build as well.

Looking very good! Regarding the feeding slots, here is a close up picture at one of the kickoff events showing the feeding slot. I don't know if you can get a good pushoff of the disc in the slot or not. If possible, I would recommend testing with a slot closer to the real field just to double check the action of the disc with the slot and your robot.
