Re: pic: 1726 in practice

Are their any bristtles or pneumatic tubing coming out of the center of the helix to help the balls up btw?

It has some of that grippy shelf liner on it, attached to form "flaps" about an inch wide.

Very interesting, any idea where to get, we were thinking of adding an agitator to our hopper to help fix jams and making our hopper bigger.

We got ours at the local WalMart for about four dollars per roll. Rather than compressing the balls to push them up the helix, the central roller slaps them really fast (1200 rpm), meaning there is very little load on the motor driving it.

We had a jamming hopper in 2006, which is one reason why we have a helix this year...a single ball path helps to prevent jamming.

If your robot design allows it, see if you can make a narrow path that the balls follow. I didn't get any pictures of your robot after you added the metal sheeting on it, but the one with the netting makes it look like the ball path is not much wider than one ball, but it doesn't really have anything at the top to keep the balls all in one line, they can bunch up next to each other.
