Here you go:

Q376 Q. Can we add grip tape or other material in addition to the fabric on our bumpers?

A. No, this would not be consistent with R21-D.

Thanks for all the great replies

Sounds like we'll keep it off the bumpers to be safe. I'll tell ya though, sure would have been nice and cured our problem of spinning the ball on the bumper material during intake.

What about silicone-impregnated fabric? That's worth a Q&A. Be sure to mention that the recommended Cordura fabric is polyurethane-impregnated Nylon.

The bumpers themselves may not have such a feature. However, you can "deploy" a mechanism over the bumper that has the grippy surface. A simple length of lexan or aluminum or even wood, hinged to flip down over the top of the bumper, should work fine. Use a servo to release it and/or nudge it down.
