That ONE Team #4967 and D-Cubed (904) are hosting the second annual That ONE Offseason Tournament on August 29.

https://www.thatoneteam.org/offseason

If you are in the area and want to come watch, the tournament is free to watch.

Feel free to DM me with questions (or post them here).

We’re team MisCar 1574, building a new custom swerve and deciding between 2.25" wide black neoprene tread on a billet aluminum wheel, or the SDS Spike Grip wheel (4" OD × 2.25"). We’ve been running 1" neoprene on our previous custom swerve.

Looking for experience from teams who ran either option in the 2026 season:

1. **Tread replacement frequency** — How many times per season (or per event) did you replace? Fixed schedule or based on wear?

2. **Hub/wheel durability** — Any damage to the Spike Grip plastic hub, or cracking on the aluminum billet wheel? Especially from defense and hard field impacts.

for refrence here is our current swerve: https://youtube.com/shorts/4-yT3L2xsLo?si=C2HAd0se6RcwHfUT

Thanks!

So we made some progress on The Lions Den since...4 days ago, Here's the link again: 5806 Scout

and here's what's new:

Offline availability - It works without wifi now, we're still working on some ways to sync when still offline, but currently it syncs to the cloud when you're online

Customizable forms - pit scout and match scout forms are now fully customizable per team per comp, so you're not stuck with our layouts if you all scout differently

Manual Q&A - our most anticipated feature actually works now, it's a little slow(takes a few seconds) but it's functional and way better than FIRST's pdf

Dark mode - self explanatory, its amazing

iPads/kindles - it's more usable right now, but we're continuing to modify dimension to fully integrate it, phones are not set yet

Bug Fixes - various small fixes from stuff people ran into

Here's what on our radar for what to add:

• Format for Phones
• Ability to change colors and team logos
• Match scout - this will happen when the game comes out

We're soo grateful for all your help and are looking forward to more of your questions, comments, and suggestions!

Hey everyone! My teammate and I from 5806 have been building a scouting app during the offseason called The Lions Den. It’s still a work in progress, but we wanted to share it here and get some feedback while we keep improving it.
Link: FRC Scouting
Quick rundown of what’s in it so far:
• Sister Team Support – If your program has multiple teams, you can share scouting data and coordinate between sister teams without juggling multiple systems.
• Talkie – Probably our favorite feature. It’s an in-app chat where you can message scouts or your pit crew and assign tasks like “Scout Match 34” or “Go check out Team 254’s pit,” all without needing a separate group chat or spreadsheet.
• Pit Dashboard – A live pit to-do list that keeps your pit crew organized. It also flashes as your team’s queuing time gets closer so everyone knows when it’s time to wrap up and head to the field.
• Manual Q&A – Ask questions about the game manual, and AI will find the answer for you instead of making you Ctrl+F through the PDF at 2 a.m. before quals.
• Pit Scout – Standard pit scouting forms for collecting robot information before matches.
• Match Scout – Live match scouting (we’ll customize it each season based on the game).
• Event – Event schedules and information in one place.
• Picklist – Build your alliance selection list directly from your scouting data.
• Assignments – Assign scouts to matches so nothing gets missed.
• Data – View, sort, and analyze everything your team has collected.
• Team – Manage team members and profiles within the app.
It’s just the two of us building this (with a little help from Claude Code), so it’s not open source yet. We’re planning to clean things up and release the GitHub repo once it’s in a better state.
We’d love any feedback, bug reports, or feature ideas if you get a chance to try it out. We’re actively developing it, so expect things to keep changing and improving!

Hey everyone! I’m a student developer from Team 4388 and I’ve been spending my summer building a passion project for Hack Club called Robolens.

I wanted to build something that actually solves real pit and competition headaches, so I am putting together a mobile-friendly app with lots of features. Currently, it has two:

1. You take a photo of your robot, and it uses an AI model to check for visual problems.

2. We always lose track of which batteries are dying mid-match in the pit. This lets the whole team log in, see a shared dashboard, and mark batteries as charging, in use, or available. It logs flags/notes for weak batteries so nobody accidentally grabs a bad one right before a playoff match.

The Tech yap:

Built with Flutter for the frontend, Node.js/Express on the backend, and MongoDB. I also just hooked it up to the official FIRST Events API so that when a team registers, it automatically pulls and verifies your official team name straight from FIRST!

The app is live on GitHub Pages: https://mirage54321.github.io/Robolens/
View my progress on Hacklcub: https://stardance.hackclub.com/projects/16179

You don't need to sign up to test it! Just click "Sign in as Guest" and use team 4388 to see our battery dashboard.

I need your feedback!

* FRC mentors and drive teams: Would your team actually use a digital dashboard like this pit-side?

* For the AI scanner, I'm currently trying to transition from a single photo to a guided video stream. If anyone has experience doing guided camera UI tracking in Flutter, I’d love some advice.

* Most importantly: what else should I add??

Let me know what you think! Let me know if you spot any bugs.

Hey FRC students! I'm in vex and idk if you have seen any of my videos or posts on here, but I am making a mini frc rebuilt robot. I have a turret working and it is made to shoot nerf rival foam balls. I am now stuck on an indexer and have been for a while. I have limited space and use power functions motors so they take up a decent chunk of my space. Does anyone here know how I could build a VERY compact indexer (preferably a spindexer) into a space of 9x16 studs or so.

I have included some photos of previous iterations as well to give you an idea of what I'm going for. They do work, but jam far too easily and the belt system doesn't work well with large amounts of "fuel" in the hopper due to jamming. The belt system uses rubber bands.

Moving back to Sri Lanka after having joined an FRC team in Australia, it has quite literally been one of the best things in my life. I know this is definitely an ambitious reach, but I'm willing to put through the nights if it means I can go for a regional.

I know that a bunch of you are going to say start smaller with an FTC team or so, but it doesn't scratch that itch the same.

For context I am a student with about 2 years of school left once I move. The biggest problems I think I have are:

• Community vs school (strongly leaning towards community, just so that it is more accessible for grants/funding and doesn't have the legal aspect a school one does)
• Who/how to approach companies and people for sponsorships or mentoring (maybe those of our First Global team? They would be in the area better. Companies-wise do I go for multiple smaller companies or a few bigger ones?)
• Getting around the cracked import state as of now, with import taxes being high and shipping taking a while.
• Where to go for regionals/chances at worlds (Taipai/China would be cheapest, for about 40% in travel fair Australia works which I'd really like to do. Obviously theres a 0.01% chance of making worlds right of the bat, but what should be the general strategy around this?)

I'm doing fgc this year and need 10 cm closed-cell polyurethane foam balls that weigh 62 grams, which is really particular and difficult to find out in the wild. We could get them from the official REV website but with shipping 60 cost about 500 euros which is mad. Did anyone have any wholesalers that they used to get the ones for this comp? Or any place that would have stuff like this?

To specifically any electrical engineers, so I still have these spark maxes that were destroyed by the neo 2021 issue. I was wondering a couple things, is it possible to replace the MCU with the CBT6 version (less ram and flash) as its significantly cheaper but has the exact same architecture and then just reflash it? I have a couple units with the same exact issue, no powor through either usb c or 12V. If there is any trouble shooting tips to know what needs to be replaced, that would be great. I have donor boards for replacement parts, but I am not sure what is even the issue for not powering on.

I come from a team entirely student ran with no actual mentors (we have two "coaches" to meet the frc regulations but they don't know anything about robotics). Im just curious on how much they help out.

hi guys, are there anymore games about FRC like mosim or closim. these two are really the only ones that ive been playing recently and im not sure where to look for more. If there is more and someone would like to send names that would be greatly appreciated.

Hey r/FRC — I'm a high schooler on an FRC team. I got tired of FRC knowledge

being scattered across the WPILib docs, old Chief Delphi threads, and vendor

sites, so I built LearnFRC (https://learnfrc.systemerr.com) — free, structured

lessons for every department: mechanical, CAD, programming (WPILib), electrical,

controls & sensors, strategy/scouting, drive team, business, outreach/Impact,

media, plus a getting-started track for rookies.

Everything's researched and fact-checked against primary sources (WPILib, FIRST,

REV/CTRE/Limelight, Chief Delphi, The Blue Alliance) and cites them so you can

dig deeper. 100% free, no account needed to read — make one and you get progress

tracking + XP if you want.

I just shipped a big redesign and would genuinely love feedback, especially:

- anything inaccurate or out of date (I fix it fast)

- departments/topics you wish were covered

- whether it actually helps rookies vs veterans

Solo student project, free forever, not selling anything. Thanks for taking a look!

Because of the war and missiles the season in Israel did not happen and is only being ran now (the teams that came to worlds was based on an informal event)

8044 denham venom 5829 awtybots 4192 jaguar robotics

Can anyone explain to me what happened during the Curie alliance pick this year at worlds? I'm rewatching worlds and looking back at the picks, team 5907 was visibly mad at 6369 for accepting they're pick. Can anyone explain please?

There was a site made to help younger students to learn to code for FRC, since it's different compared to the usual.

Please provide feedback on the code samples I used as Im not as familiar in Python or C++

EDIT: Also check out the GitHub repository if you'd like to look at the source code or fork it to provide some features!

Some sensitive topics are briefly discussed, and have been put in spoilers, don’t take this post too seriously, a lot of it is just me noticing things about anonymity online, with one case here

Hello folks, if you are active on Instagram, you may be aware of the account titled “FRC Confessions”. What started as relatively harmless fun has quickly devolved into borderline slander, a gross misuse of the internet, as well as a disgusting look for FRC students.

An account that is dedicated to anonymous confessions from FRC members, the FRC Confessions page is a stain on the FIRST community as a whole. Posts frequently include slander of students, alumni, mentors, and teams as a whole. Personal insults have become commonplace, including calling students of teams fat, manipulative, smelly, and other not so kind words. Topics also frequently discuss Sexual themes between students, as well as accusations of pedophilia.Accusing teams of cheating is commonplace, and content is far removed from any of the FIRST core values.

The core concept of the account, anonymous, uncensored confessions, farms into a toxic culture that enforces a culture in which slander and bullying is perfectly fine, as long as no one knows who is the aggressor. As a community, FIRST has done nothing but strive to bring people all around the globe together, and it is an incredibly bad look for us to continue feeding into this culture of hatred and harrassment. I ask you not to go harrass the account or it’s owner, but it is important to bring this to the attention of you all.

Since writing this post, multiple new confessions have been posted, including calling a student a “fat bitch”, and a rant about LGBTQ+ of FIRST, comparing Dean Kamen having strong ties to Epstein to showing inclusion for pride.

the config / reset button came off our limelight 4 since i was attempting to flash limelight os onto the Limelight (photon vision -> limelight os),

i tried to put it back onto the little contact pin board thingy, however i noticed that there was not anything that could contact the little pins. I tried using an allen wrench to try shorting it, but i could not see a usb connection on my computer. i believe that there was a metal ring that was supposed to be attached under the blue plunger to make contact with the pins, but idk. any ideas?

So another shooting game? (hopes for a Stacking game evaporating sound effect, heard in the background)

​

What do yall think, how much of this (if any) could be seen in Bio-Core?

Hi all — I'm Jahaan, software lead on Team 5835. Over the past while I built LearnFRC (https://learnfrc.systemerr.com), a free site with structured guides for every department of FRC — not just programming.

It covers mechanical, CAD, programming, electrical, drive team, scouting & strategy, business/operations, media & outreach, the Impact Award, safety, and getting started. There are 390+ lessons, each researched and fact-checked against current sources (WPILib docs, the 2026 game manual, REV/CTRE, The Blue Alliance, Statbotics, etc.).

A few things that might be useful for your team:

- A "Start here" prerequisite track for each department — e.g. a quick Java primer before robot code, basic electricity before wiring, forces/torque before mechanisms.

- A short quiz on every lesson so members actually retain it.

- Progress tracking, XP, streaks, per-department completion certificates, and a leaderboard.

- 100% free, no paywall.

It's aimed at rookies and at anyone training new members during the offseason and preseason.

I'd genuinely appreciate feedback — what's missing, anything that looks wrong, and what would actually help your team. Thanks for taking a look!
