We have seen a few videos of robots with under the bumper note intake mechanisms but they seem to be running on hard surfaces. We would appreciate if anyone has any experience running then on carpet and can share.
Thank you
The notes slide very easily on field carpet. There is a rather small contact ares against the floor, thus very little friction.
Driving into the note with a vertical panel on the robot frame, or bumpers within 1 inch of the ground, the nores bounced off the robot and slid around the field when we drove into them. I dont think it would stick to the carpet and get wedged under the robot unless the lower edge of your bumper or frame was pushing on the note around 1.5 inches above the floor, thus pinching the note down into the carpet.

haven’t ran it on carpet yet but these were the results of our designs first testing on our competition bot, save to say we are extremely happy with it.

we have a couple of videos here showing BTB intake and shooter. https://www.youtube.com/@LynkFRC/shorts
We’ve got some on our blog and youtube channel:
There’s also some where it doesn’t work as well:
Hope this helps!

Here is a link to a post on my team’s build thread talking about our under the bumper intake prototype. As you can probably tell in the videos, the notes aren’t going under a bumper but it was just a prototype and we tested with a sample piece of bumper and forgot to take video. As you may also see in that post, it works incredibly well.
If you’d like some specifications of what we used for the prototype and are planning to use for our final design, I’d be happy to provide those.

Shoot, my bad. Thanks for letting me know.
I don’t have any closeups but you can see us picking up notes while driving in this video. Our intake is two rollers with 2" thrifty bot wheels in line with the shooter and a single kicker roller right up against the front of the frame.
