I'm guessing one of the missing mechanisms is something to hold the ball in the arm cup when driving? Or does the intake do that as well? Can't wait to see the whole thing - please make a release video!

A release video would be sweet!

This robot is looking awesome I cannot imagine the headaches y'all had fitting everything in a size similar to Mittens, but without the arm. Looking forward to seeing this at Madtown.

The things that caught my eye are the compact compressor bracket and the wheels.

It looks like you cut openings in the polycarb and then bent it.
How did you bend it? Was it heated in an oven and then put into a form?

On the wheels, they look worn down. Did you sand off tread to make it turn easier?

We built a catapult prototype, but not with the adjustable stop, scoop, or turret.

There will be a pair of omni wheels that help to hold the ball in place, and pivot downwards when firing.

We cut the polycarb on our CNC router and made the bends using a heat gun and a press/break. The wheels are just used ones from the season, nothing special.

Got a part number or link to them? I haven't seen those before but they look intriguing.

Blind Rivet Supply sells a wide assortment, they'll be labeled as "large flange" rivets.

Well, we did prototype the adjustable scoop, just as a manual adjustment.

Fastenal is where we got them.

Definitely a swing away from the usual simple swiss knife style, but I love it. Wish I could be at Madtown!

You know you've made it big when people assume every imperfection is genius!

[Bryce2471]

I intended to watch this robot play at Madtown, but I apparently tuned in too late.
How did it turn out? What were the learning experiences?

It was pretty terrible

That's a little harsh. While it didn't perform fantastically, I still thought it was a phenomenal piece of engineering and thoroughly enjoyed seeing it.

Not harsh at all, as it seriously didn’t work. I’m going to post a render and more details, including lessons learned, sometime next week.

Would you mind posting a model of that compressor bracket? I'd love to 3d print one of those.

Seems like it was geared really fast. Was this the case or was there just no ramping code?
