That's a Turner's Cube.

Devin's pride and joy.

The catapult will be powered by both surgical tubing and pneumatic cylinders. We just haven't mounted them yet.

Looks gorgeous, hopefully one day I can dive into the CAD of this thing.

Gotta ask though, what's with the giant rivets?

Re: pic: 1678 Offseason Robot Progress
 

Awesome looking bot! I can't wait to see the final product.

How will you access the electronics for maintenance or repair?

PS. Love the random things in the rest of this photo

That reasoning has led you this far, and it looks stunning. Did any prototyping in the offseason go into this, or did you perhaps test a catapult during the build season?

I would love to see some more pictures from different angles, or maybe even a video once it is operational :D


+1.

This robot is absolutely beautiful. I hope y'all will show it off at ccc. I'd love to see it.

Re: pic: 1678 Offseason Robot Progress
 

We got those by accident during the season, and are just trying to get rid of them.

The entire turret assembly (and everything on it) can be unbolted from the drivetrain, but the electronics are a huge pain to access.

We did a couple of weeks of prototyping in June, but the rest was done in CAD over the summer. I will upload more pictures when we finish it, along with some other specs.

With great difficulty and possibly tears :P

The electronics on this bot are pretty crazy, given how small it is. We ended up needing to mount the PCM on the turret, because it won't fit elsewhere.

You're seeing one of the two independent shot adjustment mechanisms ;)

My boredom and associated hijinks are the stuff of legend.

Re: pic: 1678 Offseason Robot Progress
 

I assume an adjustable hard stop? I don't think the adjustable cradle is enough with a single throw length to get a fender shot, and considering I see what appears to be a mount for spring assist, you'll need/want some kind of Hardstop. Maybe that's what the empty pocket in the plate the catapult rotates around is for? A VP to adjust the throw?

Everytime I've looked at this picture (a lot of times) I've noticed something cooler. My favorite part may be that the catapult is offset by ~30 degrees on the turret to allow for a longer lever arm.

This robot is all about the little details, pun intended.

Re: pic: 1678 Offseason Robot Progress
 

Yes, there is an adjustable hard stop that uses a custom tiny disc brake. At least that's how I understand it is going to be.

Re: pic: 1678 Offseason Robot Progress
 

Has 1678 bought up the world supply of disc brakes? You guys sure do love that stuff :P

I'd love to see this up close (as I'm sure others would as well) so I'm curious if the team would be able to show some of the details that we might not otherwise catch in photos like these. It would be a fantastic learning experience.

Otherwise, wicked cool stuff! Props to the team for the hard work over the summer.

Re: pic: 1678 Offseason Robot Progress
 

Did you build a functional prototype of the catapult with all these articulations?
I get the feeling that building the prototype would be a major challenge in itself, probably worthy of CAD.
