We made our reveal video after the first competition last year :stuck_out_tongue_closed_eyes:.
Students had a lot of fun takin over the performing art center to make it!

SuperNURDs Offseason Summary!

This offseason we decided to be more ambitious we have in any prior year, doing many new projects, initiatives, and public resources!

2024 Accomplishments:

  • Built a new offseason robot
  • Built a rookie football shooter robot
  • Held zoom calls with other 9 FRC teams across the world!
  • Created new circulumn for teaching new students
  • Got to collaborate with some amazing groups/organizations on social media
  • Hit over 260 million instagram views! :open_mouth:

2024 Offseason Robot “Two-Face”

This robot was made by our veteran students, beginning in July, and competed at Battle at the Border, and Beach Blitz! We tried many new things on this robot, like our sheet metal elevator “Plate-Evator”, 3D printed flywheel hubs, a 25x25 swerve drive, and double sided belts. We learned many things as a team and are very grateful for the knowledge it gave us!

2024 Offseason Training Projects

This offseason, we developed 3 different mini mechanical projects to teach our rookies before build season, with an offseason robot being their final project. These 3 mini projects are the, “Dice Project”, “Fidget Spinner Project”, and “Sheet Metal Car Project”. This year the offseason, “Sport robot”, was designed to shoot footballs, with a parent showcase being their competition and motivation to get the robot finished.

We had a great experience learning how to properly operate and run these projects, with many lessons learned. Some portions/projects turned out great, and others needed far more development time.

Huge thanks to everyone who read our build thread last year! I hope these resources can be useful for the 2025 season. Best of luck!

Very cool to see how y’all approached a football robot! Did any prototyping go into this in terms of getting the football to orient correctly in that funnel? Would love to see some of that.

3255 had one of the best build blogs last season and more people should be paying attention to this thread!

SuperNURDs Offseason Code!

To go along with our CAD releases, below are all of our code repositories on GitHub. All of our robot code from every previous years, along with our SuperCORE standard java library, are all publicly available on our main GitHub.

This offseason our team decided to switch to a state machine coding paradigm in order to make more robust and error tolerant code. We believe this was a successful experiment and plan to embrace state machines in the build season as well.

Another major change this off-season was to embrace WPILib’s new Unit libraries. We found in the past that a lot of our “code gremlins”, were due to incorrect unit conversions. We found that leveraging the units library as well as moving away from NetworkTables based RobotPreferences resulted in less human error.

Yes! it was rather difficult to get the football to orient correctly, we started with our “Cardboard Aided Design”, hopper, to get the ball to flow to a set of rollers. Once in the hopper on the real robot we initially had difficulty getting the ball to feed from the transfer to shooter uniformly, but added 1 sheet angled polycarbonate at the bottom, reduced the wheel size, and it began working much better!

FRC 2025 Season Trailer!

How we run our kickoff!

Heres a short timetable of how we run our kickoff meeting! Let me know if you have any questions. We ran a mock kickoff today with ourselves and FRC Team 9730, the Metal Maniacs, following a similar structure, but with the FRC 2019 Game, Destination Deep Space!

22 Cycle Reefscape Match with 2024 Robot

During our meeting today we ran cycles with our 2024 robot on the fully taped field to get an idea of how fast cycle times would be. We discovered we could score 22 pieces when having an intake on the front and an outake on the rear. There are many factors/variables, but running a robot on a taped field taught us a lot about the game!

This is very unrealistic.

You’d empty that station 2/3s of the way through.

In all seriousness, thanks for doing these driving trials. The Kitbot driven and programmed well should be putting up over 40 points a match at these rates.

(also, nice to see the CNC and concrete tables have found less obtrusive homes)

Realism isn’t really the point here; I do agree that this many cycles isn’t that realistic haha (unless we’re talking Einsteins or something). Does raise some questions on the difficulty of the 15-20 coral rp though

The point of the exercise was to see what our limiting factors would be in a match. It looks like driving won’t be one of them; lineup and mechanism movement will end up determining how long a cycle is, so we’ll need to prioritize those in our design. We also wanted to identify insights such as having an intake on the opposing side of your scorer that will cut down on the already mechanism-dependent cycle time

(And i don’t miss the tables either lol)

Those are some pretty fast cycles! If you have another chassis, could you try to see what defended cycles could look like and how big of an impact it has?

There should still be coral in the station with 22 scored, 1 missed intake.

There are 57-60 coral split between the two stations and they had a preload, so there would still be another 5-7 coral available.

Ah yeah, I blanked and thought it was 15 per station.

Week 1 Recap Video

Week one task completed:

  • Ran cycles with 2024 robot
  • Competed game scoring analysis
  • Identified robot’s feature important list on 1-5 scale
  • Decided overall robot architecture
  • Prototyped Coral hopper/placer mechanism
  • Completed a minimum viable prototype robot
  • Wrote prototype robot autos and logic!

We are excited as ever to resume next week, and will be publishing more videos soon!
