I'll choose door number two, Bob.

The 2nd one is sweet. The 1st one has too many holes in it - It looks like swiss cheese.


::Edit:: Those treads look familiar. Our wheels are gonna be more pimp than yours, though .

Re: pic: 229 "Bling" for 2005

IN MY OPINION, THE SECOND ONE IS DEFENETLY BETTER BECAUSE THE FIRST ONE LOOKS LIKE IF YOU HAD MADE HOLES TO REDUCE WEIGHT AND THE ONE ON THE RIGHT LOOKS REALLY COOL.

the one on the right

They need to be green anodized, and then assembled with yellow anodized spinners. ... and then, on the spinners, you can etch "JVN is a dweeb".

That would be cool.

Those look familiar

Although we welded our flange onto the purchased rims. I assume you milled these. BEAUTIFUL! I'm a right winger myself. I see you riveted the seams on. We found some incredible glue to hold that on without any mechanical fasteners. I was asked not to divulge, but I'll give a hint - shoe repair.

The one on the right looks much better, and it looks like it might weigh a little less, too.

Well well well...I guess some people just can't stop at bling bling for the brain, can they?

And yeah, my vote's with the second one.

Re: pic: 229 "Bling" for 2005

The wheel on the left looks like an off-road style, as for the one on the right is more of a street style.

I like the one on the right

31-01-2005 11:10

If they weigh the same, I like the one on the right more.

Re: pic: 229 "Bling" for 2005

i'm gonna have to break with everyone else and say the one on the left. either way, if you decide not to use one set or the other, team 1369 would be happy to relieve you of the excess wheels.

31-01-2005 12:14

Franchesca

Re: pic: 229 "Bling" for 2005

I agree ... I think as far as style goes, neither of them are bad. If they both weigh the same, why not go for the one on the left??

And ... I like swiss cheese ...

Re: pic: 229 "Bling" for 2005

Dan,

The reason we went with rivets instead of adhesive is for ease of changing tread at competition. All we have to do is drill out 4 rivets and pop 4 more back in to the new tread. We have tried adhesives in the past and the problem is usually drying time and excess glue on the wheel when changing tread. If you have found a glue which works well, that is excellent.

Did my 2004 wheels mate, have deformed kids with 2 extra mounting holes, and then sell their offspring to you on the black market?

Sexy wheels, man... no matter which you go with.

Re: pic: 229 "Bling" for 2005

If JVN did that then maybe his robot could be a showcase item on "Pimp My Robot" But, wouldn't spinners add a little too much weight for what they are worth, but hey that's an IRI idea for teams to do!

31-01-2005 13:26

Joe Ross

Re: pic: 229 "Bling" for 2005

It appears that there is less material overall for the wheels on the right. I assume everyone is picking those in order to make sure they have the greatest chance of 229's wheels breaking in competition.

31-01-2005 15:22

Re: pic: 229 "Bling" for 2005

Yeah, if they break then they suddenly become much less pimp...

Re: pic: 229 "Bling" for 2005

I do not think that either of those wheels would break during a FIRST competition. I do like the one on the right by itself, but if the one on the left looks better on the robot I would go with it.

Re: pic: 229 "Bling" for 2005

Thanks for the compliments... We really appreciate them.

The original design (wheel on the left) was done this fall as (note my avatar animation). Unfortunately we didn't meet all our design specifications...

I am (along with Eric and 4 others) part of a senior mechanical design team assigned to 229 (as part of our senior integrated design capstone class). One of our design specifications (created mostly as a joke) was: "4 out of 5 high schoolers must agree the robot is 'blingin'." (You can imagine how difficult it is to create a quantitative specification for "bling".)

The original design didn't make the cut, so we had to go back to the drawing board. The wheel on the right is the final result, and the one that will be on the competition robot.

Each wheel involves about 3 hours of CNC time, plus a few hours of "lathe time". (These wheels are cut from a length of 4" aluminum rod.)
(When 179 posted their prebought wheels, I felt like a chump! I guess we "wasted" our effort, but at least the wheels turned out great, and the HSers got some CNC quality time.)

We thought about spinners, and even have a design done... but we're fighting the weight monster this year. Maybe it will happen, probably not.

As far as "JVN is a dweeb"... I hear 229 may be handing out fake tattoos with that very slogan! That and: "Andy Baker is the God of Hick Rock!"

These wheels won't break. We performed FEA on them using Ansys and they're fine.

We've been running on them for 3 days now, and the tread is staying on just fine. We've done the "epoxy thing" before, and it was just a huge hassle. Changing tread now is as easy as 4 drilled holes, and 4 new rivets. (The pit crew keeps whining about "design for maintenance" and such.)

Thanks again for the compliments...

Re: pic: 229 "Bling" for 2005

Wait wait wait. You made those out of a single piece of rod? Wow, i guess it would be sturdier that way, and I suppose since it has to be blingin it was the only way, but dude. We got ours water jetted. Just got them back today and we'll probably post a picture of them. But after seeing yours, I doubt anyone will care. Good job man.

why design for maitnence john? we arent going to break anyway right?

and i must again tell they're both awesome designs.

Re: pic: 229 "Bling" for 2005

Ahh young grasshopper... good question.

For our viewers at home:
The tread material we're using wears down during continual usage.
We will need to swap out and replace old treads probably once a regional.

Or... because of our design, we may just "rotate the tires".
Can any of you budding young designers figure out why?

Re: pic: 229 "Bling" for 2005

Because you'll have a 6WD bot with the 4 corners having a bit less wear than the center wheels, since they're lowered?

02-02-2005 17:38

Matt Goulart

Re: pic: 229 "Bling" for 2005

I would take the one on the right.

02-02-2005 17:38

tkwetzel

Re: pic: 229 "Bling" for 2005

I also don't think that you will have perfect weight distribution and the tread that has more weight on it will wear down faster than treads with less weight on them.

02-02-2005 18:04

Geoff P.

Re: pic: 229 "Bling" for 2005

the one on the right looks much more professional. the one on the left just looks drilled for lightening. i would say the one on the right, although i'm not a big fan of gold.

Re: pic: 229 "Bling" for 2005

So these are the wheels alekat wus talking bout... lol.... NICE! i like the one on the left more industrial looking... this year we had our first custom wheels
we were going to mill ours out of a rod but due to cost issues.... we made 2 piece rims... we milled the outer rims frome pipe and had the center spokes waterjetted pretty sweet although we can't beat the level of blingosity established by yours

04-02-2005 20:15

Travis Covington

Re: pic: 229 "Bling" for 2005

I would almost say that the outer 4 wheels will require more frequent tread replacement as the center two are less likely to slip. I assume the tread wears more rapidly with slipping side forces.

I actually like the one on the left, they remind me of 258's wheels.

Hey John!

Where are the SpreeWheels? You gotta get the spinners if you really wanna flash some Bling Bling out there!

Nice job by the way... I may have to leave a couple of cinder blocks under your bot in exchange for those after the competitions.
