what material is that black foam? thick weatherstripping? ive been searching for something exactly like that for a while now

McMaster #4463K123

You can also just search for "foam" there to get a lot of different styles.

Hey... wait... that looks like a LEGAL bumper configuration! You can't post a photo with a legal configuration... we'd have nothing to talk about!

Looks like a nice intake, hope it inhales the balls like a teenager inhales pizza.

On a scale from 1 to nice that looks pretty flippin nice. I can't wait to see your team in Connecticut.

is that pneumatic tubing? if so how did you attach the ends?

Re: pic: GUS Team 228's 2009 Teaser #1
 

Yes it is pneumatic tubing and the ends are probably some how melted together (correct me if I am wrong). 102 used this same design in 2006 and it worked rather well.

While I'm not on 228, I'm 99.9% sure it's orange 1/4" urethane belting from McMaster. It's pretty fantastic stuff, see this thread. In the provided link, there's an in depth welding guide (by Art from 228), but essentially you melt the ends and smoosh them together in a piece of aluminum angle. Let it cool for five (ish) minutes, and you're ready to go!

Close. The loops are 3/16" orange urethane belting (McMaster-brand polycord), and the teeth on the bottom roller are 1/4".

The heat welded joints in the polycord are holding up just fine so far, although our full speed testing (2200 rpm) has been limited.

reminds me of an earlier winning bot.
