WCP CADathon 2024: DunkTank

Hey guys! 7461 Sushi Squad here. Sorry we are a little late to the party, but we are here now!

Here is a picture of our robot for this dunkin’ amazing cadathon:

The name of this bot is “Sakura”. If you are curious about our design, feel free to read our documentation… it explains it all.

Some (a tiny amount) of cool solutions i’ve learned from these awesome submissions:

587

587’s robot, Backhoe, easily has one of the best-packaged basketball scoring systems. They also designed it modularly, with a low cg, and the list of things they would change is incredibly useful to see. Backhoe being designed by just two people is crazy, especially considering how well-written the tech binder is.

1086

1086’s robot, the CHSy Champion, is already very cool. The electrolyte system is especially cool, with it (seemingly) being able to intake from both ground and loading chute. The ball scoring system also makes this robot pretty competitive, and I will definitely want to see the final design.

1189

1189’s robot, Freddy 2.0.1, is probably the best MCC robot. I also think 1189’s tech binder is the one most worth reading.

1778

1778’s basketball solution is very simple and effective. Their full-frame intake feeding into the scoring box is a really good design (and also packaged very cleanly). I think the team’s post is probably the most useful for teams to learn from, and I’m excited to see the robot in its final form.

2583

2583’s robot, Layup, has an awesome passthrough transfer across their elevator for basketball scoring. The solution is really simple and effective, and I also think still using an externally driven elevator, even after using internal rigging in their offseason robot, was a smart choice. This robot is really simple and effective, and I’d love to see it in person.

2910

2910’s robot, Cal Raleigh, is maybe the best electrolyte cycler I’ve seen. The massive electrolyte storage system can easily lock down an rp (and a ton of points during endgame), and the lightweight design (only 91 lbs?!) will be great to learn from. While illegal, this design is certainly another 2910 classic.

3847

3847’s robot, Steph Current, is packaged very nicely and has an interesting transfer between their full-frame basketball intake and their dunker. The sliding roller intake is really interesting, but the hing-floor system is insanely well-thought. Spectrum never disappoints, and this robot (and wonderful blog/documentation) is no different.

Craig

Lastly, Craig’s robot, LePookieBron, is plain awesome. Craig’s basketball intake and scoring system is very-well thought out, and allows a tiny robot with plenty of electrolyte scoring capabilities. I can’t wait to see the CAD and tech binder, and I’m definitely putting a dinosaur into our 2025 robot.

All of the submissions were phenomenal, and 4192 is better than we were on Sunday thanks to these robots. I can wait for People’s Choice voting, considering how many cool features all these bots have.

I have been informed that some teams haven’t yet posted their submissions to this thread, so I’ve created a Google Sheet that has every submission on it for reference: WCP CADathon Submissions 2024 - Google Sheets

We didn’t know we were supposed to post the Models and stuff here. Well, Team 5461 V.E.R.N. developed Barnebee! See our Corgi Inclusive Breakdown!

Will rankings be published, or just top 3?

There are too many good submissions to choose from

Just award winners, maybe some honorable mentions. Too many to give an objective rank to each one.

man, I’m not gonna lie I’m trying to earnestly pick a top 3 just from pictures in the thread and it’s hard. I do not envy y’all trying to actually judge the complete submission.

So, this got put on the backburner.
PINKOUT consisted of 2 designers and 1 documenter, totaling to about 35 man hours.
While we technically have a fleshed out design, time constraints (also a hurricane) pushed a lot of stuff out the picture.

What got cut

What got cut?
High scoring (measured wrong a couple times, big fumble)
Tubing + brackets for hopper
Expanding hopper
Motor to floor rollers (I forgot :frowning: )
Kicker for shooter
Shooter support
Electronics
Pneumatics in CAD
Finished documentation
Better renders (SW Visualize hates me)
Probably more I’m forgetting

Team 4065 presents our WCP CADathon 2024: DunkTank robot, PINKOUT.





Special features include:
Battery destroying elevator
Custom 1" elevator plates (1 side CNC 3/8" 6061-T6 aluminum, super easy)

CAD release soon (pack & go issues as usual)
I can answer any questions

Lessons learned:
Don’t get attached to a certain architecture. At the release of the game, we really wanted a double intake design to make autos easier and enable “shift” autos, seen especially by 1323 in the 2024 season. This would probably not work at all in practice, given the uncertainty of bounces by ejecting out the back (wanted because of 1678 in 2022). If something works better than your original design, don’t be afraid to change it. With more time provided, the elevator would be shifted to one side (which would eliminate the double sided scoring, but could score High), single intake, with the rest of the space reserved for a hopper. There’s probably a Spectrum Blog post about doing exactly this.

Think things through from the start. A lot of this robot we just said to ourselves that it would work out in the end. Not so much. The hopper was super phoned-in towards the end and really got screwed over by design choices outlined in point 1.

Great game though :slight_smile:

I love your solution to the electrolyte system. Rolling up the cloth is so innovative!

Here is my robot concept it is a little late bc I have been busy during the week;
It is split into two major sides, one for the basketballs and one for the whiffle balls. For the basket balls it uses a full width over the bumper intake, and a elevator with a arm perpendicular to the intake so that the robot can score on two sides of the robot. The elevator is also offset from the center line which will help with dunking the basketballs in a hoop while next to another robot.
For the whiffle ball side

Are you on track to have results posted as per the initial timeline or are you expecting them to be delayed/by how much? Just curious.

We’ll see after judge-a-palooza this weekend.

You know you’re cooked when you’re thinking more about the CADathon results instead of the Early Action deadline

Here is 9277’s robot. Sorry for the delayed post. We didn’t realize that we need to submit our robot design here as well. So sorry about that. Attached to this message is the google drive link for all our resources including our cad files, our strategy and build info. Again, I am very sorry about the delay.
