I would do a puncher, I changed my mind about a flywheel. I’ve tried it and it did not work as I hoped.

In Rapid Relay, I think Catapults will be used more because fly-wheels would require lifting the ball onto the flywheel. Most teams who have trouble with this might stick to option #3 though.

Do you mind elaborating on that? I’m thinking about using a conveyor belt type mechanism to launch it. Similar to the intakes in V5RC.

Could you elaborate on this. What happened when you tried it?

Not that I can build a robot. But if you think about the strategy you put together, lots are focused on the first 6" (picking up the ball") and the last 1" (scoring). I’m interested in what your plans are for the ball crossing the middle 6’. Will your shooter do double duty to get it to that distance?

Hi, we try 2, 4 and even 6 motor flywhell and no success against the peluchness of the ball. Too squichy. We had one good flywheel shooter 3 year ago. but no succes this year.

When I tried it on the CAD it seemed to work, but I hooked it up and it was not as powerful as I expected. I probably should have just had a larger gear ratio, but school is out and I can’t test anything.

When you say flywheel what do you mean? I have a very specific idea that I am fairly sure is not the correct use of the term but I am just wondering whether when you say flywheel you mean something similar to the shooters in the 2022-2023 VEX IQ game slapshot or something else. I realise it might be a lot to ask but any sketches/pictures would help a lot. Thanks

If I were in Vex IQ, I would just build this bot but with iq parts

I’ll be using both a conveyor belt launcher like @Joeboticswastaken and a catapult which will allow mo to score in both goals.

You will use both? I’m planning to do a three motor drive (H drive I believe is what it’s called) and use two motors for the conveyor belt catapult and possibly a PTO to add more power. I feel like a pto might be a good way to adjust the power. The new Ben Lipper bot looks good but only a two motor drive and also I know that people can potentially remove themselves from winning something like the design award or excellence for using a Ben Lipper design

This is sort of what I was thinking (3 motor H-drive, 2 motor conveyor belt intake [with an additional intake] and 1 motor cata). I hope your’s works!

Ohh so you’re just using the conveyor belt as an intake? I think the benefit of that is it seems to be more reliable than a rubber band intake. I also wanted to see what other people think about this, I think that this season the robot will matter less and it will be more about the driver, alternatively, it might also become, how many motors can you add to your drivetrain.

I’m using bubble tires at the front.
What are “bubble tires”? Are they omni wheels?
They are likely the air tires in the second generation kit.
very heavy sigh All, and I mean ALL of the VEX IQ parts have names. Can you make an effort to use them? No such things as bubble tires (or softies, squishies, smushies, smashies, marshy, mushy, or even hollow roundies) I’d love to assume that you are talking about balloon tires. If you are, here is a pro-tip, the BALLOON TIRES come in multiple sizes, so after saying Balloon tires you might want to say what size.
2x Wide, 7x Pitch Diameter Balloon Tire
2x Wide, 5.5x Pitch Diameter Balloon Tire
2x Wide, 3.5x Pitch Diameter Balloon Tire
2x Wide, 5x Pitch Diameter Balloon Tire

Thank you for helping your fellow roboteers with not introducing new jargon.

Oh, I read bubble tires on vex. My bad.
Thanks this was really helpful, I might use this to test diiferent ideas.
