 The biggest fallacy in FIRST is the belief we are just a bunch of different teams. We are ONE BIG TEAM with a lot of sub teams for the purpose of competition. - Al Skierkiewicz [more] |

Re: Vacuum
I'd like to see one with only one point of contact on a Trackball that actually would work. I don't think it will.
The reason I say this, is because the fabric outer covering of the Trackballs will not result in a very good seal as the nice one layer vinyl tube would last year. If you tried this, you would probably need 2 or more on quite opposite sides of a ball, and in that case, why even bother adding the venturi mechanism when you basically have a gripper with 2 points of contact anyways?
