Hoops

[Grim Tuesday]

Where do we get 'em? They don't look like they're in the KoP, and there are no retailers listed.

[ehochstein]

It is a Huffy 7800 Slam Jam Basketball Rim. You can find it on Amazon and Sears.com ::rtm:: it is hidden in one of the arena sketches.

Edit: I do not remember what the net was called but it comes separate.

[Grim Tuesday]

Can anyone find any of them for less than $47? It seems ridiculous for a simple plastic hoop with some strings attached to it.

[kjohnson]

We ordered ours from Wal-Mart (http://www.walmart.com/ip/Spalding-7800-Slam-Jam-Basketball-Rim/5650973) for $28.54, but they are out of stock online already.

[ehochstein]

You might be able to find one of ebay for cheap

I found one here (http://www.ebay.com/itm/Spalding-Huffy-7800-Basketball-Slam-Jam-Rim-Goal-W-Net-/140676745129?_trksid=p4340.m185&_trkparms=algo%3DSIC.NPJS%26its%3DI%252BC%26itu%3D UA%26otn%3D5%26pmod%3D320734584763%26ps%3D63%26clk id%3D5459402049083004076#ht_3359wt_1139)

I am sure you can find one that is almost a replica of the Huffy but for cheap as well.

The official description/product numbers:

Rim: Huffy Spalding “Slam Jam” Red Replacement Basketball Rim, model #7800s
Net: Lifetime Basketball Net 120gram, model #0790
Spring (replaces the stock one): McMaster #9573K68

All from Section 2.2.4 of the Game Manual. Great move by the GDC to put all those part numbers in the Manual so we can (relatively) easily find the exact parts.

[DjMaddius]

On Amazon they are $33,

NVM, lol, earlier they were $33, now they are $47 -__- Demand rose suddenly, hmm, I wonder why lol

[Greg Needel]

I got ours on amazon when they were cheaper, It looks like loads of retailers sell the same product.

We picked up a functionally identical rim at Sports Authority for $34. They did not have them on the floor when we were there, but when we asked for just the rim/net they had them in back.

Cory,
can you post a link to the model?

Cory,
can you post a link to the model?

I'm not finding anything on their website that's priced the same as what we got. I can get the item number tomorrow and post that.

[J-Blondie]

The ones from Sport's Authority are Lifetime brand. I am not sure on the exact specs and out store didn't know but they are basically regulation size hoops and the ones you can get from there should work. We got two and they were $34 and come with nylon nets. We plan on making any others we need.

We measured them and they are identical to the Huffy one.

Now that you said Lifetime that sounds familiar. I think I mixed up the brand.

[pfreivald]

I ordered some from SportsKids.com this morning for $34. I think it's just the hoops -- I really don't need the nets to test robot functionality.

However, I was picky enough to order the exact right part, because I want it to respond/bounce/etc exactly like the field elements.

[lbarger]

It's not a simple plastic hoop. What FIRST has specified is a steel regulation basket ball rim. That said, you should find it cheaper at Amazon, ~$31.

The question I have is whether or not the break away feature is needed. Robot extensions are limited to 14", robots can not climb on the 'fenders' and the rims are over the finders. Can an appendage contact the rims? Would game play (ball reaction) be very different if you used a fixed solid rim?

[Breakaway3937]

I purchased ours from Target.com for $34.99. You can find the link here (http://www.target.com/p/Spalding-Slam-Jam-Basketball-Rim/-/A-10613799).

[sanddrag]

Is the Spalding not just functionally equivalent, but identical to the Huffy?

The breakaway feature is to make it easier for the reset crew to retrieve stuck balls.

[Cory]

without having compared two side by side I would hesitate to say yes, but based off of the dimensions given by FIRST it certainly is.

[martin417]

The "breakaway" feature (not related to the 20010 game of the same name) WILL make an impact on game play. They stated that the spring was replaced with a softer one. The rim will deflect when struck by a ball, thereby absorbing some energy. This will affect the way the balls bounce off the rim. Your practice hoop should be mounted the same way for consistency.

The rules effectively prohibit robots from touching the rims, but there's nothing physically prohibiting a robot from breaking the rules. Imagine a 150-pound robot tipping over onto the end of one of the hoops.

[waialua359]

well we finally ordered 3 of them.
After searching site after site, they were either sold out or an outrageous price with shipping.
It was a whopping $243.xx!:mad:

What rule is this? The fender is there to protect the rims, but there is no rule barring contact with the fender, or even climbing on top of it. Granted, it would be difficult to do, given its height, and probably not worthwhile.

[PVCMike]

Can anyone share how many springs are in each hoop? Every hoop I can remember playing on has had 2 but I wanted to make sure before I ordered springs.

Edit: Never mind. Found it in the drawings. Only one spring per hoop.

[mtnDewey]

The hoops' dimensions are the same as other regulation size basketball hoops. We just picked up a few from our local sporting equipment store, didn't have to pay for shipping, and got them right away.

[sanddrag]

After I ordered my Huffy hoops, the receipt said Huffy Spalding. So, by my logic they must be the same hoop.

[MrForbes]

I visited several likely stores in our small town (50k+ people), and came up with nothing. There are no basketball hoops in town. There are a few backboards with hoops, but that's a lot of extra money for something we don't need.

I guess it's time to order something online....

[Mr. Pockets]

To anyone who has actually gotten ahold of one of baskets in question: would using a standard regulation basketball net give substantially performance results?

[silverD]

Walmart (http://www.walmart.com/ip/Spalding-7800-Slam-Jam-Basketball-Rim/5650973) has them back in stock. I ordered 4 and will be shipped to store. They are quoting arrival after the 20th.

[Brandon Holley]

To anyone who has actually gotten ahold of one of baskets in question: would using a standard regulation basketball net give substantially performance results?

Its a tough question to answer. FIRST has spent time to specify not only a different spring for the hoop, but a different net as well. I recall reading somewhere in the drawings that the additions would be fine for practice, but the real field would be using the substitutions theyve implemented. A regulation size basketball hoop is a regulation size basketball hoop. Functionally it SHOULD be the same, but theres really no guarantees unless you got them side by side.

It seems that changing out the springs and netting on whatever hoop you get would be worthwhile simply to make sure you are designing to what the field will offer.

Thanks for the Walmart tip! Ordered 3 today. Would be nice if at least one was in the KOP.

Edit. Most home use nets are very cheap. I have a hunch that the nets provided are closer to an NBA model where it's a heavier nylon cord. Unfortunately our midwest kickoff was the team field, Not the FIRST field.

[tlivingd]

Sorry to spam this thread.
for those who haven't seen the game specific drawings, the notes below are on drawing GE-12013.

"Notes:
1. Remove stock net. It will not be used for competitions. It if fine for practice, but the
length may not be compatible for the rest of the field components.
2. Remove stock spring from the backboard and replace with the specified spring from
McMaster. Once again, the stock spring is probably good enough for practice, but the
McMaster spring has more give to it. "

[RoboCat2005]

As for practice reason, we talked to our schools basketball coach and got some old rims that were laying around. Although not the "actual" rim, they are regulation and meet the same dimensions so for practice reasons will work. Biggest benefit, did not cost us a thing.

[Aren Siekmeier]

We've been slowly bringing them in from people who have hoops at home and never use them. It's 4 nuts to undo and you have your hoop, and then plywood makes a fine backboard.

[Gray Adams]

While trying to make your field parts as close to official parts is nice, it really isn't necessary for something like hoops. An 18" hoop is an 18" hoop. If seems to me that if whatever you're working on is so absolutely reliant on a certain spring stiffness in the hoops (hoops that you're never even going to touch), then you'reg going to have trouble no matter what.

Just take a look at the difference between the low cost ramp, and the official ramp. It sure is nice to have that built to spec perfect field, but it really isn't necessary.

G10 as modified by team update on 1/10.

Robots may not push or react against the top of the Fender.

The soft springs in the official competition hoops are likely to make the basketballs bounce less when they hit the rim. I suspect it will be easier for them to go in.

Same for us in Honolulu.... Shipping was $37.00 for each rim!
::ouch::

[WizenedEE]

The soft springs in the official competition hoops are likely to make the basketballs bounce less when they hit the rim. I suspect it will be easier for them to go in.

In my mind, it either goes in without bending the hoop at all or it's pure luck and we can't change our design to compensate for it. What's the point?

Anyway, wouldn't the springs only kick in if the ball hit the top of the rim, in which case you missed anyway?

[Lavapicker]

I found them online at sports authority. For Hawaii teachers, I used the 15% off from my HSTA card. Shipping was still close to $50 but The total was closer to $150 for three. I'm looking forward to replacing my 15 year old rim at home when the season is over.

Big 5 carries Lifetime Slam II Rims at 39.99. I called the closest store which had 2 in stock. They had 2 more by the next day.
