T-Fling, choo choo, or ratchet for launcher?

VEX IQ General Discussion
1

What is the best launching mechanism out of these three? In my opinion it’s probably a T-fling.

Of the three, Winch is the easiest to tune and most versatile, along with being pretty fast and being quite easy to build and structure. Choo choo is the hardest to tune and build, and often results in bad build quality as they aren’t the greatest due to the intense power put on unstructured capped shafts. And finally, T flings. They are the speediest of the three, but the angle upon which they can pull down isn’t that large. Most of them barely pull down and this was great for games like pitching in.

Hopes this helps!

What’s T-fling and Ratchet?
My team are building a choo choo and it’s pretty fiddly

The ratchet is the mechanism Swish has.

@VexBuilder77 I’ll also ask, what is a T fling, is there some other name it would be known by?

Cool, I learned something and got a Caution Tape video too!

It looks like you could stack multiple T and gear sets together to build up enough power to launch heavy things.

That’s actually really cool. I remember the days of choo choos that were scary. This is such a clean mechanism. Love to see this sort of innovation in IQ

My team is thinking about using t-fling. we used a pnematic cata with bi-stable booster but this looks much better.

Is it powered by rubber bands or pneumatics?

Is it powered by rubber bands or pneumatics?

Full pneumatic accutation with 4 short pistons. It could only shoot low goals and had a cycle time of four seconds. Thats what i get for trying to reinvent the meta.

Does anyone know how do you build A T-fling?!?! My team can not build one

We just finished building one. It’s actually not too hard to build! We used a 1:5 ratio with one motor, and we can consistiencly score a ball in the high goal (we have a back roller)

Instead of using a “T” shaped piece, use a 1x5 linear slide rail. There is a lot less friction.

Caution tape has a good video of the mechanism. Try to build a small prototype before doing it on a robot.

Can you send me a picture? Also my team thought that we couldn’t use gear ratios

Try instead just looking up an in depth explanation, VexBuilder77 put a good one on there:
