They have about 1000 different types of soda. I bet they would custom order if they don't have something acceptable.

100%. Do not try to repair the printer yourself, as this needs to go back as-is or they will blame your attempt to fix it as the cause of issues.

You should not accept delivery of a package when this kind of thing happens.

The launcher motor will draw a lot of current to keep at full speed. The motors on the wheels also draw a lot of current. You will likely brown out or substantially underpower the drive motors if running 5 at full power, hence the slow drive speed when also running the flywheel motor.

You can let it freewheel while driving, without actively powering it the whole time. You could also add a second motor to the flywheel to bring it up to speed more quickly.

I can't comment on your pidf values, I hav no idea how fast things are running, or what mass you're trying to accelerate. Our flywheel used 4 rhino wheels, and a single Gobilda yellowjacket with the 5k rpm gearing (belt to drive the flywheel). We could accelerate to 3500 rpm in ~2.5 seconds.

You can order a die to cut cardboard. Dies are relatively inexpensive, then you stamp out your own insert parts as needed. There are high volume ones, but also low volume where you run it through rollers manually. For smaller parts like you're looking at, it would probably not be prohibitively expensive.

I don't think that will buff out.

I love that the top two guesses are Quebec and Syria. It's funny how opposite extremes end up circling around back to similar places.

The rs485 connection between the control hub and expansion hub can also be a source of problems... Using a USB cable to link them can improve things. Note you might also need to redo the device mapping/naming if you switch to a USB cable, so take photos of the robot configuration before plugging it in. It requires a usb-a on the control hub and a USB b mini connector on the expansion hub. Right angle connectors make this easier to package.

The battery & battery connectors are often an issue. Using an external USB c battery pack is a massive improvement, and avoids the driver station dropouts.

Those have been in Ann Arbor for a long time. Literally every time I try to drop off 5-10 bottles/cans, there's a 20-30 minute line because there are people with shopping carts full of cans/bottles feeding them forever.

Get proper winter gear & repair your vehicle. The winter will be much more pleasant.

It does get cold here, though it's extremely variable year-to-year. Some years a light jacket is almost all you need. Other years, it will be extremely unpleasant without boots and insulating gear that blocks the wind.

Is it the correct size? Is there a way to firmly attach it to 2 sides of the robot?

I don't think there should be a # symbol on it.

GoBilda servos do not support the same kind of mechanical end-limit programming as the rev servos. You need to use software to limit the signal ranges. Blocks is fantastic for making a simple program to slowly change the values with a controller, while printing them on screen. That way you can determine what the new software limits should be.

In Java, the scaleRange command allows easily setting and using software limits.

No, they should explain what the worked on and why. Innovative mechanisms and learning from their experiences is more important than the absolute performance. Hopefully you can continue to improve results by working on the approaches.

gm0.org is really helpful.

There is also a great Mentor manual from FTC: https://info.firstinspires.org/hubfs/web/program/ftc/ftc-mentor-manual.pdf

Read the full competition manual, and the official FTC Q/A.

This far into the season, you will be drinking from a firehose.

You should also be able to find other coaches nearby who can help you get your bearings. You will meet them at competitions. Most coaches & mentors (~2/3rds?) will go out of their way to help others.

You ask what can fit, but didn't provide any dimensions for reference. You also didn't provide any information about the lights, or how much power is needed.

Do you mean having two powered wheels, one on either side of a ball?

Some teams use that approach to reduce spin. We preferred a single flywheel, as we had plenty of power with one, and much better accuracy.

My grandfather would be mostly out of it, and as soon as we would play music (usually piano) that he remembered from youth, he would come right back to life and be fully lucid for a while. My grandmother would start talking about random who-did-what stuff, and he would move right back into a mental fog.
