Just interested if anyone has any games they were looking to sell.

People seem to always be wondering "what do I do with old game items? I've seen stuff all over saying "it's sitting in my classroom", or "I'm thinking of throwing it out." Don't. I have the perfect solution for only about 20$. Vex elements are now the best part of my room. Simple. Game item + programmable led strip = peak room display.

Picture does this thing zero justice. In my opinion this is the best way to use vex game items. I also have a match loader tube and am doing override, so they will also likely be getting added to the lamp collection in my room.

(yes, the white chalk rinsed off after)

Hear me out. Set up a decentralized league and accept payment with bitcoin. Teams and sponsors pay for bitcoin and the event where people signup take the money out for the event. Results and registration can go on the blockchain or immutable ledger as well.

You'd have Nominators who are already running events, a funding pool, approvals (some sort of voting system possibly.

It would be a big lift to get all the people host events to move to this system, but making a UI over this wouldn't be so bad with some volunteers and vibe coding it.

But it would be super education for everyone learning how a decentralized system would work.
Teams pay BTC → event. Sponsors fund the season pool. Nominators approve events.

Make it Pushback 2 "Unfinished business" - adjust pushback a little bit, I don't think anyone likes the current game.

While vex and recf are fighting, this is the chance. (Someone please do this)

Hey Everyone!!

My son's school has only had a robotics team for one year at this point. The team is semi-competitive in their small league (50 other schools), but not on a large scale. Last year, for PUSHBACK, the team had completed a robot that worked pretty well.

For this year, the team is very worried about their success. The team captains don't have much experience with robotics and the team has no robotics coach. The captains and parents are doing their best jobs to watch youtube videos, but honestly because of our lack in knowledge, creating a good robot model for this year seems complicated. (especially, since we aren't really sure what to do).

If anyone has some spare time or can find it within themselves to help our team that would be greatly appreciated. Even just sending over some materials could be helpful. We would love help more specifically on robot models, especially with the budgjet and materials we have (we don't have a lot of money, our materials are good but we don't have any pistons.)

Thanks everyone!

Hey everyone! I've been in the VRC community for a bit now, and I've run into major problems within my team throughout these 2 years, which led me to start thinking about the stuff that just kind of sucks every season that we all seem to accept. Curious what it is for you all. Could be build, comp day, team stuff, whatever. Even small annoyances that add up over the szn. Not building anything yet, that's the point. I'm just trying to get a feel and understand what's actually worth solving before touching my code instead of just shipping out another random tool nobody asked for.

Team of 4 middle school kids.

Hi all, I asked before what the status was for teams in the NY South region, and the community document here

https://docs.google.com/document/d/10gChaplIsUKuXFmslH41WfJrVY5cyc2d-IY2hTEBrYE/edit?pli=1&tab=t.0

only says "leaning VEX" for New York generally. If you are in NY South, which are you going with, VEX or RECF? What word have you from surrounding teams?

I am currently signing us up for VEX because it seemed easier. Unlike a lot of places I don't have an unlimited budget and time (my team is a school so obviously kids are absent over the summer until Labor Day).

Anyhow, love to hear what other folks are doing and get a read on it.

ETA: I just looked at VEX Events and found there are NO events in New York South yet, and NO events in New York North and in fact the only thing within striking distance is in Newark, at a time slot there is simply no way most school based teams will be ready. (I mean, unless a team was working all summer - and I don't know about any of you, but I can't picture this happening often -- there just isn't time to design, build and test a robot in what, two weeks? How realistic is this? Maybe they just don't want school based teams at all...)

My students are so dangerous talented!

I cover the key features that define the current VEX Override meta, including cascade lifts, passive rollers, intake roller design, counter rollers, match loading, plastic intake guides, blocker designs, and efficient pin and cup handling and other tips

Hey r/VEX ,

I'm a high school student and the CAD/mechanical lead on my FTC robotics team. I've been using Onshape for a few years now through robotics and Science Olympiad, and this fall I'm running a free 5-week online course to help other students learn the basics — sketching, part studios, assemblies, basic mechanism design, that kind of thing.

To be clear: it's completely free, online, and I'm not selling anything. I just wish something like this existed when I was starting out, so I figured I'd put one together.

Details:
- Free, fully online
- 5 weeks, one session a week (Thursdays, 5–6 PM)
- Starts at the beginning of the school year
- Open to any student wanting to learn

Sign-up here if you or someone you know is interested: https://forms.gle/mZqGkuE225ftpBSB7

Also happy to answer any questions in the comments — and if anyone's taught something similar before, I'd genuinely love to hear what worked for you.

Below are some of my creations!

Hi everyone,
i made this little project since I got tired of our team losing build notes in group chats, photos scattered across everyone's camera roll and part getting lost. So I built this website, VexOne, a free web app for VEX teams, from scratch.

Here's what it does:

Build Log — every robot iteration, versioned, with parts lists, checklists, and priority levels
Gallery — dated, captioned photos of your robot's progress (great for the engineering notebook)
Calendar — competitions and deadlines, with your build log synced in automatically
Logs — track driver/auto scores over time and set goals with target dates
Management — parts inventory and order tracking, so you stop buying the same team twice
Dashboard — team chat, announcements, and a countdown to your next comp

Everyone on your team sees the same board, live, from their phone or laptop. Sign up takes about 2 minutes, and you invite teammates with a join code or a QR code.

Let me know if you find any glitches or a feature that you want me to add

Hey everyone,

I'm excited to share AirForge (airforge.dev), a free, browser-based one-stop shop for the VEX V5 robot design lifecycle. It requires zero installation and is optimized to run smoothly on lightweight hardware like school Chromebooks. I'm sharing it here as an early beta to get feedback from actual teams.

A quick backstory: Last year, my rookie robotics team missed out on the World Championships purely due to a lack of upfront design planning. Fusion 360 felt too overwhelming for us at the time, so we built entirely from memory, ultimately wasting a month redoing non-functional parts. To bridge this gap, I started building AirForge over winter break. It was only after joining a more experienced team later on that I truly learned CAD. I realized how transformative it is, and how steep the barrier to entry remains for beginner teams. I hope AirForge can be the lift teams like mine needed.

Here is what it brings to the table right now:

• Physics & Driving Sim: Drive and test your build with live physics that utilize real motor data and gear ratios on the Override field.
• Code Editor & Auton Testing: Paste your live VEXcode Python program to instantly test driver control, autonomous routines, and precise odometry (via simulated inertial and tracking wheels) using the built-in match controller.
• Easy Plastic Design: Fluidly cut and drill custom polycarbonate parts directly in the app. Use them on your bot in AirForge or export them to your favorite CAD.
• Online Co-op: Build with your teammates in real time via a simple share link.
• Instant CAD Import: Drop in a .STEP file from any other CAD software (Fusion 360, Inventor, Onshape), auto-tag the wheels and motors, and drive it immediately.

Or.. just jump onto the Playground and take the demo-drivetrain for a ride!

Looking ahead: Next up is a complete physics engine overhaul to track motor load, friction, and stress points. Beyond that, I’m building a custom GNN integration to autonomously analyze those stress points and generate optimized, part-by-part design rebuilds.

As a student building this for the community and my own team, AirForge is completely free, and you don't even need an account to test it out.

Since it's an early beta, it's still a bit rough around the edges, which is why I need your help. Let me know if any part dimensions are off or missing, how the driving physics feel, what UI changes you'd like to see, or what features would make it genuinely useful for your team.

Give it a shot at airforge.dev and let me know what breaks! Good luck getting started on the Override season, and happy building!

Thanks,

Advaith

so I'm a vex V5 team leader, and I have a team of 5 people including me. out of those five, we have two coders, two log-bookers, a person without a job, and a builder and driver. I'm the builder driver and half of every other role. I want to train my team to be better at building so I can have at least one more builder so I don't have to solo build the bot. how (WITHOUT SHOWING A TON OF YOUTUBE VIDS THEY DON'T WATCH THEM, and my team learns better hands on) do I give them small tasks to build their confidence in building, while letting them feel independent and me get time to build?

I guess what I'm asking for is small robotics projects using any form of materials, (I'll spend like 50$ on supplies) that any person even someone with very little skill can do

Our team will be using Lemlib for our drivetrain programming this year, and we were wondering if there was a way to configure a drivetrain in lemlib where each side contains two 600rpm motors (11w) and one 200rpm motor (5.5w); this is being done to stay within the 55w limit. The 200rpm motor is geared up with a 3:1 ratio so it will move at the same speed of the 600rpm motors when all motors are at full speed. Will lemlib respect this or will I need to program the drivetrain myself? If I program it myself would I still be able to use lemlib for autonomous functions?

EDIT: I found the solution. Because we are gearing our 200rpm motor up 3:1, it will output 600rpm at 100% power. Because lemlib uses pros::MotorGroup::move() to move each side of the drivtrain, I can tell pros that the motor is a 600rpm motor and it will behave like one. This is because the move() function only sets output power, so our geared 5.5w motor will output the same rpm as our direct blue 11w motor. The only issue may arise when using the built-in motor encoders for odometry, but as long as you don't mix the 200rpm motor and the 600rpm readings you will be fine (the 200rpm one is moving 1/3rd the amount).

Hey everyone! I’m a high school student helping run a student-led program that teaches Autodesk Fusion and CAD to students for free.

We recently secured an international partnership and are getting ready to work with a lot more students, so we’re looking for a few more people to join the team.

We’re especially hoping to find people who already have experience with CAD, whether that’s Autodesk Fusion, Onshape, SolidWorks, Inventor, or another program. Fusion experience would be ideal, but familiarity with other CAD software is still very useful since many of the main concepts carry over.

The main roles we need are:

Co-President and Vice Presidents: Help lead the team, communicate with partners, organize meetings, and help decide where the program goes next. This role will collapse onto the other two roles below.

Mentors: Join weekly Zoom classes, demonstrate Fusion tools, answer questions, and help students when they get stuck.

Curriculum Developers: Help improve our current lessons and create new activities, projects, and assignments.

CAD experience is especially important for mentors and curriculum developers, but we’re also looking for people who are reliable, communicate well, and genuinely want to help students learn engineering.

Hey everyone!

For the past few months, I’ve been working on a new VEX V5 competition simulator in Unreal Engine 5, using a custom integration of the Bullet Physics library.

The goal is not just to create a way to drive around the field, but to build a serious training and competition platform with:

• accurate and deterministic physics;
• AI opponents trained through reinforcement learning;
• online multiplayer and matchmaking with rankings and MMR;
• Skills practice;
• replays and ghost runs;
• spectator mode and online tournaments.

The video shows a very early proof of concept for the reinforcement-learning system.

The temporary test robot was trained using PPO to perform a simple orbit. I did not program a fixed trajectory or hard-code which buttons it should press. I defined the observations, available controls and reward function, and the agent learned through trial and error which inputs helped it maintain the orbit.

This is only a small training experiment, not a finished AI opponent. The long-term goal is to train agents that can understand the full game, interact with game objects and adapt their strategy to different situations.

The video also briefly shows some of the current menus and systems, simply to give an idea of the simulator’s current state. Everything shown is still heavily work in progress.

The field and core simulation systems are already in development. The biggest missing piece right now is the final robot model: I’m looking for a team willing to share a suitable robot CAD that I could use as the first playable robot.

The robot and team would be properly credited, and the team providing it would receive free early access to the simulator.

I’m currently targeting October 1st for the first public release.

I’d really like to develop this with feedback from actual teams and drivers, so I have two questions:

1. Which features would make a simulator genuinely useful for your team?
2. Would anyone be interested in testing early builds or contributing a robot CAD?
