Perhaps both? ;-]

Our original design was more ambitious than this, but lack of resources forced us to narrow our scope some.

On the bright side, it's a week 'til ship day and all we have to so is a little programming, some mechanical tweaking, and crate building.

See y'all at UCF and Lone Star!

A Few comments and questions. One: Are the balls brought up by rollers of one side, and afixed side on the other? Because four years ago, First had a game that involved picking up soccer balls and we had a robot IDENTICLE to that. Our problem was one side was fixed, the other rollers. So as the balls a sucked up they bunch, and so the rotation of a ball in front would conflict with the rotation with the one behind it. That not make much sense, it does in my mind I just cant tell you real well.

That makes perfect sense. We are having a single sided conveyor. We are relying on the fact that it would be quite unlikely for us to pick up two in a row (due to natural scatter of the balls on the field).

In our system we have room for 2 balls side by side, both sides are on rollers so that the balls continuously spin. On the bottom there is a divider, so the ball either has to go up the right side or the left side, as the balls get sucked in and are spinning they seperate on either side for about 3 stacks, then begin to settle in the middle. As we suck up additional balls they push the other ball to the right or left side.

So because the ball enters on the left or the right side it pushes the balls that reside in the middle to the opposite side.

The system is pretty sound, we still have some binding issues but its mainly the balls pushing against the lexan, and when the bot moves around they seem to sort themselves out. I'll be posting a short teaser style video to show more of how the system works, and some more detailed pictures later.

I think you have built an incredibly nice robot for a rookie team. The fact that you built it in half of a garage makes it even more impressive. Really good work.
