No Pneumatics on 870 in 22. Intake stayed out, but was flexible and very compliant in most directions.
3357 hasnât used pneumatics in 2023, 2022, or 2020

Easily half of the robots I inspected this year had no pneumatic system, which just happens to be my favorite pneumatic system.
230 had no pneumatics in 2016, 2018, 2019, or 2022.

7160 didnât use pneumatics last year and our climber was just run on a motor with a string inside which snapped during our offseason comp in October. We thought about using pneumatics this year but didnât want to pop cubes, so we used pid controllers on our motors for positioning.
7845 didnât use pneumatics on rapid react.
No pneumatics last year - the only thing we would have used them on would have been the intake (so it could fold in when we run into a wall), and we got around that with a friction brake.
This year, we used pneumatics. Intake, extension, and a bicycle brake to hold the arm up.
Generally speaking, we consider what we would need pneumatics for, and if itâs not multiple uses, then we find a different way to do it. Thereâs a lot that goes into it (weight and complexity!) for just one actuation.

217 didnât use pneumatics this year
No pneumatics for 4476 in 2022 or 2023.
No pneumatics for 5413. We were purely mechanical.
1690 didnât use pneumatics in 2022 (or most years in recent memory for that matter), as for how we built our intake, we had a little âclutchâ mechanism to allow it to collapse when pushed too hard(explained at ~2:30 in our BtB video)
Robonauts had a three-position actuation powered by a joint with two pneumatic cylinders.

We had versplanetaries deploy our intake (donât recommend), 775 and an Andy mark sport gear box with some additional gearing rotate our robot on the monkey bar and the wcp telescope for lifting
if you give further reduction via chain or gears versaplantarys work quite well for that purpose. we have used that for a few years now

The way I had them mounted, it twisted the gearbox a lot and broke the bracket more than once. I guess the chain would alleviate that but space was limited. And it was my first year as a designer
