Hopper Capacity

[henryBsick]

I just thought I would add to the growing number of polls out there for robot statistics

[Nuttyman54]

we're 21-24 as is, but may get more capacity if we add on (we allowed room for expansion)

[RoboMadi]

31-40.....
depending on the situation i shud say.

[phrontist]

Psssh. No one needs more than 20.

Where does that logic come from? I think if you can handle more than twenty go for it.

[Richsgt]

Definitely can do more than 20 because if you have all the balls your opponent can't keep them away from you. Besides more is always better

I would love to see those who voted 70-all
is that even physically possible considering the size of the ball?

It can be done. http://www.chiefdelphi.com/forums/pi...le&picid=12757
That's our machine....not all of the lexan is storage but there is a possibility of holding up to 96 balls in our hopper. We are looking to lose weight and the hopper might end up on the wrong side of the hacksaw if you know what I mean

Yes! it is possible. The ball is about 7 inches. A cube that would hold the ball would have a volume of 7^3 or 343 cubic inches. The volume allowed for the robot is 60X60X60 inches. That is 216000 cubic inches. 343 into 216000 is just over 629. If the robot didn't expand the volume would be 64904 cubic inches. Divide that by 343 and you get 189. Collecting all the balls would still leave about half the volume for other robot parts!

Wow. If I see a functional robot that can hold all the balls and score points, I will be amazed. I know our robot can pick up two balls at a time from the ground, and I think she is supposed to be able to hold ten balls at a time, but don't quote me on that. This is going to be quite an interesting competition this year....

Actually.. well.. yeah.. sure... You may be right. I fit 149 in this configuration here - Minus gravity of course.

Oh, and as far as my stance on this thread in general, Hoppers are way overrated for the simple fact that they have potential for jamming.

[lukevanoort]

We have a switchback magazine/hopper design (it has metal bars in a sort of Z configuration) that can hold ~8, our conveyor can hold ~4 and another ~6 or so can go on top. These are all estimates based on a mentor's CAD of the robot, which I have evidence to distrust. We couldn't test them before ship b/c we have only three balls. My more realistic (I think) count from eyballing is ~5 in the hopper thing, four on top and five in the conveyor. Still, we figure since the opposing team's human player isn't going to throw US the ball, more would be excessive. (I wanted ~20, but this should work... I hope)

1604 has held up to 24 balls and wasn't even half full. We can pick balls up from the ground, but I can only really see us getting lots of balls if we fill it up while the robot is on our side of the field during defense period. I don't see picking up balls as good of a strategy as playing defense, but I may be wrong. Being able to control all balls on the field so the opponents can't score may turn out to be a better strategy, but we shall see.

1390 can hold 10 balls in its conveyor belt at max capacity.



Quick funny story on balls in the 1604 hopper... We were weighing it on a scale at the school one day. It came up to be 24.1 lbs. Baffled, I tried to think of everything we have added on to the robot since the last time we weighed it. One of the students looked up and asked "Do the balls make a difference?" I look up "uhhh oh yeah, Yes!" after removing about 8 of them, we were back down to 118 lbs.

The last time I read the game rules.....points in goals 1 or 3, points in hopper....0! Why carry more than you can shoot?

Ken

[Nimmy]

it's not more then yo ucan shoot, what about pouring?
besides if you can pass those balls to your alliance-mates? why not
even better, if you control the balls in the field you can score points so that you lead by 5, gather all the balls, get up on the ramp
there ya go, you win
don't think of balls as points for yourself
think of them as points for the opposition
