Hmm… what is this… o.o?
Btw, our robot is about 95% done. =D
For once in our team’s history we are close to finishing before the shipping date…
More teasers later.
Hmm… what is this… o.o?
thats a large half wheel of cheese . .
giant hard candy?
That would make a sweet ballast.
That is very punny! 
I detect a catapult.
It’s a giant jawbreaker?
Or a plastic/fiberglass scooper?
:]
second to the catapult idea.
I say it is a half circle (hallow) component of a roller/conveyor system
Half a fan duct?
Looks like one of those high speed hand dryers.
I think what you are seeing here is a mold. For fiberglass vacuforming. I think the end part will be a transition segment for the top of the shooter (the part the ball presses against before it gets shot out)
thinking more on it it kind of looks like a rubber top like the pinball machines use to launch the ball.
safety helmet:D
