Flywheel foam?

I noticed that on some robot reveals that people were putting this foam like material around their flywheels. What is this foam and is it legal?

That would be anti-slip mat. Yes it is legal and vex sells it in 12” by 15” sheets.
You can find it here.

Hey there!

@Download Complete linked the anti-slip matt, which is legal.

Vex also sells adhesive foam at this link. It’s also legal and both are actually quite good- I’d recommend putting some on your flywheel or your hood. Good luck!

PSA the adheasive foam worked wonders for our NBN flywheel.

Thank you, adhesive foam was the one I was looking for.

Awesome, happy to help!
