Team 2415: We Suck...

[sdcantrell56]

Thats pretty interesting. I wouldn't have thought to use a hand held vacuum. Ours is slightly bigger and more powerful

Awesome! How large is your dome? With our 20" dome, our vacuum system produces about 200 lbs. of attachment force. Which should be plenty.

[sdcantrell56]

We're using a 21" funnel. The biggest thing with ours is that we lock onto the ball immediately by just touching it. We dont have to be precise or wait for the vacuum to lock. I think ours was calculated at over 300lbs of force but we are also using 2 fisher price motors and a larger impeller. Either way thats an awesome robot especially for a rookie team.

[Doug Leppard]

Wow we discussed this briefly for our team and didn't think it would work, congratulations.

So did our team, we even built a vacum, but it had no where near the strenght of that one. we decided on a mortor/catapult desighn.

Honestly I didn't think it would work either but thats why we have an engineering mentor that specializes in pneumatics who had the whole thing figured out and taught all of us how it worked. We're also shooting the ball and our current prototype is getting about 6.5ft completely vertically and 12 ft when launched at a 45 degree angle

That's an amazing design.
Most definately. [:
Practice makes "perfect".
(I put perfect in quotations b/c nothing is ever perfect)

Impressive.

[GaryVoshol]

I would have never thought at team could create enough suction to pick up a ball. Great job.

Have you tried it on various inflation levels? While the balls in competition will be replaced if they go seriously flat, they will still use them if they're just a little soft.

I didn't see a good enough side-on view, so I have to ask the inevitable question - does it stay within 80 inches?

[Andrew Y.]

Yes we have tried both FULLY inflated and half way. We will actually try almost no air tomorrow.

Thanks for the compliments!

[Priyadarshy]

WOW You guys suck so much its impressive.
Good luck at regionals, maybe if you suck enough you will win a whole bunch of awards and matches!

Nice Bot. It looks like its really hard to grab the ball. how long does it take for u guys to score

awesome! great idea


P.S. Please don't let mentor martha pick the music for your next vid. K thanks

[santosh]

As of right now it isnt that easy to grab. However we have four sonar sensors that we are rigging up and we will be able to "see" on a dashboard on our laptop in order to help us grab the ball.
We don't really have a full field setup or anything and since we were in a library, we weren't able to really time it. But if we have the ball in the down position it takes about 10 seconds to score.
And the more we practice the easier it gets because that was literally the first time we drove it. But we really need to practice.
Thanks and good luck to all teams.

I really like the design. I love the thread title
