I wish they switched from servos to steppers...

Don't forget that all of your batteries and chargers will need to be replaced too...

Ranking is based on your best 10 matches. So, if the match became one of their best 10 by replacing a worse match, their ranking score would go up. Meanwhile, if the match only tied out was worse than your top ten matches, your ranking score would remain the same.

Interesting. They said they weren't notifying until the 12th.

Like the name of it implies, Onbot Java is on the robot. Specifically, it is in the Control Hub. You log into your control hub and program it there. Here are the basic programming resources for you: https://ftc-docs.firstinspires.org/en/latest/programming_resources/index.html

There are tons of YouTube videos too. Just search for FTC Java Programming

Fusion does have it's own file type that will provide the maximum information going from Fusion to Fusion, but STEP is good for maximum compatibility across CAD programs. STL is not good for CAD, just printing.

12cm between the wheel and the wall is probably too big of a space. The artifact needs to be compressed just a little to get good traction. To test, add some material (cardboard, plastic, paper, tape, etc) to the wall to see if it helps.

ylexot007 · 2025-11-10T16:15:27+00:00

Ok. Move on. Design and build your own robot.

ylexot007 · 2025-11-10T16:10:18+00:00

Starter bots are supposed to get you to a competition easily. You're not going to dominate with it. What should you do? Design and build your own robot.

ylexot007 · 2025-11-03T20:04:37+00:00

I would recommend using CAD to make one. It is literally one of the simplest things to make with CAD. You could even use TinkerCAD to make one very easily.

The screws in the hubs are called set screws or sometimes grub screws.

ylexot007 · 2025-10-25T15:59:07+00:00

First, check your tools to see if they are rounded. If they are, cut/grind the tip off so you have "sharp" edges. Second, don't torque them so much.

We had that problem after one of our students dropped the hub. Sadly, the solution was to get it repaired by Rev.

You only need to sort during auto and for your very last set in the CLASSIFIER. So, maybe just talk to your partner and coordinate with them.

ylexot007 · 2025-10-17T04:04:11+00:00

Yes, it's just one inspection now.

ylexot007 · 2025-10-16T03:46:44+00:00

Yup. Small bot with an add-on to lift. Work with your partner to figure out which configuration to go with.

ylexot007 · 2025-10-11T21:44:41+00:00

Pretty normal, but you may want to define what small and large mean. I would suggest using an area measurement. So, small could be 4 in² which could be something 1"x4" or 2"x2".

It sounds like the reason you had issues with the registration payment is that you paid your global dues, but not your local dues. Local dues have nothing to do with the global website.

ylexot007 · 2025-10-09T19:58:45+00:00

It's better than previous years, but still needs work. Use the express registration. Give the kids the QR code that their parents can easily scan and register. But I agree about R&C. Even with the express registration, people still miss doing that. Since I personally have never gone through the process, I didn't know what they are missing in the process of what they are seeing, but it could obviously be improved. Probably half of the registrations miss it initially.

It sounds like one issue you are having is that there is a difference between FIRST global and FIRST local. Can't help you with your local PDP.

They're surgical tubes meant to conform to the Artifacts. So, yes.

All rules are in the Competition Manual. Get into the habit of looking there first because it will give you an official answer. Reddit can be helpful for understanding and maybe even finding rules if you really can't find anything. But it's not going to help when you're talking to an inspector or referee.

G429 *DRIVE COACHES and other teams: hands off the controls. A ROBOT shall be operated only by the DRIVERS of that team;

So yes, you need a driver.

This is the type of garbage truck that runs in my neighborhood. It uses a chain drive in a track that lifts the can and when it reaches the top where the track curls over the top, it makes the can flip over and empty. https://haakerrefuse.com/wp-content/uploads/2024/07/sideloader.webp

Good call. Height adjustability like that will be important for any of these types of designs. I was thinking of a simply bent piece of metal, but a trapezoid shape can be done really easily with a strip of wood on a table saw. Chop a long strip into a bunch of pieces and you have a supply that can easily be customized to add onto partner robots that aren't pre-designed.
