Different types of metal used on the frame/chassis

I see a lot of robots use the u-channel metal, but then im currently using this robot that I found already built for learning the fundamentals of ftc, and it uses these sliders which you slide the hardware onto. I have a lot of the other type of metal as well. Is one better than another or should I just use both?

On a un-related note, should I build a new frame entirely or will the one I am using now work well for the upcoming season?

Odometery puds

I have rookie coders in my team, and im not also good at programming so we’re looking for some tutorials on how to do the pedro-pathing or the road runner and how to code using java

If anyone has some good resources please share them with us 🙌

Potential backfeed problems

Hello, this past season our team used a catapult to score, we also had new problems with our control amd/or expansion hubs turning off or disconnecting. I asked one of the mentors if the arm could be backfeeding into the expansion hub causing the issue, they said no and it was static from our mecanum wheels, but we have run these wheels in to past with none of the mentioned problems. I know the motor does backfeed when the robot is off because the light in the expansion hub would turn on when we turned the motor to reset the arm, but im not sure it can while the robot is on.

Control hub disconnection

We just did our first off-season competition last weekend and our control hub kept disconnecting in every game.
Whene we were practicing at our places everything was fine but when it gets close to our robot during matches it disconnects
Anybody knows why?

FTC 101 - Complete Starter Guide for New & Beginner FTC Teams

Hi r/FTC,

We just finished creating FTC 101 — a detailed starter guide made specifically for new and beginner FTC teams.

After going through our own first few seasons and helping other new teams, we decided to put everything important in one place so new teams don’t have to struggle as much as we did.

What’s inside the guide:

- FIRST Mission, Core Values & Gracious Professionalism explained clearly
- All FTC Awards (Inspire, Think, Innovate, Control, Design, etc.) with what judges actually look for
- Hardware Basics (Control Hub, Expansion Hub, Driver Station)
- Drivetrain Types Comparison (Tank, Mecanum, Swerve, X-Drive, etc. with pros & cons)
- Blocks Programming examples (TeleOp + simple Autonomous)
- Engineering Notebook & Portfolio tips (very detailed)
- Scouting strategies and Alliance Selection advice
- Outreach & Sustainability ideas (important for Inspire)
- Judging Presentation tips + common questions
- Golden rules + most common mistakes new teams make

The guide is completely free and made by Asteria Robotics #32334.

You can download it here: https://linktr.ee/asteria.32334

After opening the link, click FTC 101

We hope this helps many new teams have a smoother and more successful first season.

Feedback is very welcome! Which part should we expand in the future?

Good luck to everyone this upcoming season!

How Could the LayerOne System Better Help FTC Teams?

Hi everyone!

I'm curious what FTC teams would find most useful during the offseason.

I've been working on a free, 3D-printable robot system with the goal of making FTC more accessible for all teams. What would be the most helpful to teams during this off season?

I would love to hear your thoughts! If anyone is interested, I can share the project in the comments.

resources to prepare -- programming?

hi guys!

so as context: all of our seniors graduated, but in the time where i was on a team with them (1 season), they literally did not let me do any programming for the robot. i have experience with java through apcsa, but i dont know much about coding a robot. additionally, this is the first year of ftc (and i think learning java for some people) for the rest of the members on our programming team for the 26-27 season. so automatically, im the programming lead for this season and im honestly cooked.

what i need: resources. how do i learn? how can i help everyone else learn? are there any resources you would recommend to learn as in depth as possible?

Custom Drivetrain Feedback

I made this drivetrain with the motors embedded in the drive pods. Could someone give me some feedback on them?

Help with fgc

Hey everyone! I know this is a bit off-topic for FTC, but I'm working on a FGC (FIRST Global Challenge) robot and could use some advice from people who know their drivetrains.

Since mecanum wheels aren't included in the FGC kit, we're planning to go with an X-drive (holonomic) setup instead. We want to mount the motors for our intake (balls )using a c-channel sandwich method — two c-channels clamping the motor between them — which should give a solid, rigid mount.

My question is: how should we orient and mount the c-channels on top of the X-drive configuration? Specifically:

How do you angle the c-channel pairs on top of t X layout?,

How do you tie them back to the main frame securely?,

Any tips for sandwiching the motor cleanly between the two channels?,

We're designing in Onshape if that's relevant. Any advice, CAD references, or photos of similar builds would be hugely appreciated!

take the horizontal c channel

and put it here for the intake

Struggling with loop times

Whenever we run our main OpMode, we get low loop times around 30hz to 40hz, which messes with our PIDs and some other stuff, from what I've seen you should aim for 100hz+. Also in other OpModes even though they have less hardware and subsystems but not by a significant amount it runs at 150hz to 200hz. We tried using bulk caching but it didn't do much of a difference. This is the hardware we have on the robot if that helps: 4 wheel motors, 1 shooter motor, 1 intake motor and one turret motor, it also has three gobilda servos and one is in CR mode and finally a webcam and a limelight.

Underwater Robotics Interest

Hey everyone! I am an FTC competitor here from the Santa Clara area. I'm looking to start a community-based underwater robotics team and wanted to see if any high schoolers nearby would be interested. The plan is to compete in the MATE ROV Competition, building underwater ROVs for environmental missions. It'd be fully independent, open to any high schooler in the area, regardless of school.

Looking for people with any background in:

- Robotics (FTC/FLL/FRC experience a plus)

- Electronics/Arduino/Raspberry Pi

- Programming

- Environmental science

Drop a comment if you're a high schooler in the Bay Area and interested. Just gauging interest for now!

Past Season References for BioBuzz

Hi y’all! I was wondering what previous seasons you and your teams have been looking at for inspiration for this upcoming season.

So far, we’ve looked at Cascade Effect for ball transfer methods, Power Play for lifts and high-position scoring mechanisms, and, of course, Decode for intake ideas. We’ve started forming a pretty solid idea of what we want to build — assuming BioBuzz is what we think it is.

I’m curious what other teams are studying or taking inspiration from. What past seasons, mechanisms, or strategies have caught your attention so far?
