Hollow vs Solid Noodles?

I know legally you can have either, but which does your team prefer and why?

We were talking about ordering more noodles for the upcoming season, and we have been using solid for years, but we didn't really have a reason to over hollow, which are cheaper.

We've been using hollow. Cheaper is probably one of them. Maybe cutting of the bumper weight? My rookie year was 2017, the team started in '05. I can't even track the games that far.

Re: Hollow vs Solid Noodles?

Being able to pick up additional noodles at the local big box store makes the hollow noodles the more convenient option.

Re: Hollow vs Solid Noodles?

Hollow. Definitely cheaper, massively more available. $1 each at Dollar General in the summer, about twice that at Wal*mart during build season.

Re: Hollow vs Solid Noodles?

In theory, based on first-year college solids classes, I would assume that the hollow noodles would be better at padding collisions, while the full noodles would be better at hit sticking and would stand up to more abuse. This because the hollow noodles compress more, meaning the same impulse (i.e. change in momentum) is taken over a larger amount of time, therefore producing a smaller average force.

In practice, I don't think you'll see much difference. The weight difference is negligible, and it's rare to see teams get close to the bumper weight limit anyway. A few pounds difference in your robot's weight will probably make more of a difference than changing your pool noodle type. I don't have any data to back this up, and I haven't heard of any teams actually researching this. But honestly, you'll probably get better performance returns by putting the time into improving other aspects of your robot than testing different types of pool noodles. The best ones to get are probably whichever ones you can find easier locally, and that I can't really answer.

Re: Hollow vs Solid Noodles?

I've made a few bumpers with both hollow and solid noodles. I haven't noticed a huge durability difference between them, but the solid noodled do seem to roll off defense and field elements a bit easier.

They also can have the fabric pulled a bit tighter over them before they start to deform, which is a huge plus on the visual side, but is also much harder on the fabric over time. Not a huge deal for us as we either patch or replace our fabric as needed between events.

Re: Hollow vs Solid Noodles?

You should add an option for don't care. Weight difference is not significant unless you fill the hollow middle with metal pipe. (Please don't do this.), Some say solid is better for avoiding T-Bone pins.

Re: Hollow vs Solid Noodles?

There is more to be gained in trying different bummer fabrics then the noodle selection inside of the bumper. Many teams run different materials to try to avoid/mitigate the friction pinning effect.

Fabrics are absolutely important, but using a firm, solid noodle instead of a limp, hollow noodle is just as important. The less compressibility you have in your noodle, the less susceptible you are to friction pins. (On the flip side, you are also less able to initiate these pins)

Only scrubs initiate friction pins anyway.

Re: Hollow vs Solid Noodles?

We can fit way more ball bearings in our hollow noodles.

I hear the pros use solid noodles and then pocket them themselves.
