Re: POLL: have small balls been abandoned?
 

i'll have one for you on tuesday (next meeting)

Re: POLL: have small balls been abandoned?
 

but here's a ghetto mock-up of what we kinda want to do

Re: POLL: have small balls been abandoned?
 

good luck getting the balls out of there in an orderly fashion.. and oh, did i forget to mention you gotta get them in there first?


None of the robots revealed thusfar have even attempted to contain balls.. I see 2 reasons for this..

1. Those suckers are big and unven. And after a few rounds they'll be donuts.

2. Most of us only have 1 real game ball to test with. You pop it, you're screwed.

Re: POLL: have small balls been abandoned?
 

we have a hopper that works great. we're just not going to post pictures until we get the rest of the robot completed as well.

Re: POLL: have small balls been abandoned?
 

Is it really necessary to shoot down an idea just because you don't agree with it? Maybe the teams that have ball-holding mechanisms just aren't done yet, or don't want to reveal their designs for doing so. Have you considered that third reason?

Re: POLL: have small balls been abandoned?
 

as i said.. that is a ghetto mock up. But, the finished version is gauranteed to catch all the balls 99.9% of the time. And our human player's average practice trial is 49 out of 50

Re: POLL: have small balls been abandoned?
 

At our meetings, the word "hopper" is regarded as an obscenity. Mention it and you'll be thrown out. I have only seen one good hopper bot -- it was in 2002 and it sucked up soccer balls like mad. I don't remember what team it was, but it kicked butt in its first couple matches at nationals .... then everyone figured out all you have to do is tip it over when it becomes so top heavy because of all the balls its carrying. :D

Re: POLL: have small balls been abandoned?
 

hmm... you might not have noticed my teammate's post, but we ourselves are planning to have a ball mechanism- I did not intend to shoot it down, I was just pointing out what I believe to be the 2 main reasons why the majority of robots so far don't have a ball mechanism..


sorry if i came off a bit harsh, that was my view and my view only, please dont discriminate against 341 because of what I said

Re: POLL: have small balls been abandoned?
 

well our robot was deisind to have the big and little balls , but we had too much wieght and had to take our lifting arm off for the big ball
lol

Re: POLL: have small balls been abandoned?
 

Wow talk about pulling up a dead thread a bit late....


For the record after seeing the 571 machine in action a couple times this year, that "hopper" was pretty great

and it was team 95 in 2002

Re: POLL: have small balls been abandoned?
 

Team 95 was great, but as I recall they didnt make it to nationals in 2002.

Re: POLL: have small balls been abandoned?
 

it just came up as similar topics to another one, i didn't look at the date lol
it looked interesting anyway

Re: POLL: have small balls been abandoned?
 

We had two wings that opened and closed via pneumatic cylinders they weren't fancy just 1/2 inch PVC over I think it was 1/4 inch metal rods. We also had a ball kicker on the front of Loki. That consisted of two 8 inch wheel chair wheels belt driven from the seat motor. That seemed to work well after we built in a new transmission at Great Lakes.

Re: POLL: have small balls been abandoned?
 

what does first do with all the poped balls, i hope they recycle for the environment

Re: POLL: have small balls been abandoned?
 

Well, on Archimedes the popped balls went to whoever claimed them first.

I currently have two--one was signed by Dean and Dave, the other is sitting at my feet here in my dorm. I wear it as a hat now and then.
