Team 2415: We Suck...

This was our first day of practice. We use 4 small cims to drive and a vandoor motor to rotate the arm and a small fisher price that sucks.
We were in the high school's library.
And yes it sucks very well and is hard to pull off.
We have four sonar sensors that are being coded right now that are being configured into a dashboard to help the drivers see where the ball is in relation to the dome.
Also this vacuum is half as powerful as our real one.
If you have any questions just post away and I will answer them.
Good Luck to all teams from 2415 Westminster WiredCats Robotics

That was AWESOME! You do suck! That's an amazingly good design, especially for a rookie team.

[Josh Goodman]

Wow, that is a really cool design!!! Never would have thought of a sucker design!

[Leav]

very cool!

our team experimented with vacuums using last year's venturi generators, but our suction never worked when the suction cup was on a seam...

how did you get around that? just used more suction?

anyway that is an awesome design! you should think about maybe putting a piston in there to give the ball a little push when releasing
good luck!

Haha yeah we would if we had the weight. We are like 7 pounds over weight right now but we should be under by the end of today.
And we just used more suction. The actual suction dome that we are going to use is run by a fisher price on a one to two ratio so our turbine spins twice as fast.
Thanks and good luck to all teams.

[Akash Rastogi]

your overpass looks really loose and "springy"

That is the suckiest robot I've ever seen Nice job.

[santosh]

Haha thanks and yeah, the thing about the rack is that we knew it was going to bend so we made it higher and it is at 6' 10" in stead of 6' 6"

[VanMan]

That looks awesome!

[DarkFlame145]

that is super awesome

[sdcantrell56]

That looks pretty cool. We are doing something similar and I'm wondering if you could post up some pics to compare our systems.

Good luck and I can't wait to see it at peachtree!!

Did you make the vacuum pump yourself? If not, what did you pull it out of?

Nice idea!

Hmm... wonder where they're going to drill 7lbs worth of holes...

Wow, nice video! You guys suck pretty good.

I just hope the ball stands that still for you in competition.

Yeah, that was our one concern about tracking the ball down as well as the speed of the arm.
Regarding the ball moving around, we have some pretty skilled drivers and some sonar sensors that we are trying to use to help us with tracking the ball. We feel that it is just an issue of the drivers being able to get it, not the suction onto the ball.
But yeah you are right, we need a ton of practice because we all know with 6 robot and 4 enormous balls nothing is going to be standing still.

AWESOME idea. it definently works but its a little slowish.

Here are two pictures of our turbine. It is a Dirt Devil hand held vacuum modified to fit a Fisher-Price motor with a 1:2 gear ratio. This assembly is attached to a 20" diameter dome.
