80/20 ?!?!?!
 

So, how many teams are using 80/20 stuff.
Of course you dont need to say what its for, it may even be discouraged in this thread, im just wondering who all is utilizing it.

Re: 80/20 ?!?!?!
 

Team 219 is and im sure you will be amazed at how we used it, but im thinking that if its that good of an idea other teams have thought of it.

just wait

Re: 80/20 ?!?!?!
 

We're using 80/20 for our vertical arm, and bracing for our upper chassis

Re: 80/20 ?!?!?!
 

We're using it for our forklift mechanism.

Re: 80/20 ?!?!?!
 

1986 is definitely not using it. It seems to heavy and too expensive to make it a feasible robot material. If you have the money and are underweight, then more power to you!

Re: 80/20 ?!?!?!
 

We're using it for the manipulator and drive train.

Re: 80/20 ?!?!?!
 

We've ordered some. :(

(Just for a tiny bit of the robot, though.)

Re: 80/20 ?!?!?!
 

yeah... we use 80/20 in some way just about every year. this year, for our base and maybe a few other things...

Re: 80/20 ?!?!?!
 

excuse my ignorance, but what exactly is the 80/20 stuff?

Re: 80/20 ?!?!?!
 

ditto for 1123. We used it on our arm last year, and plan to use it again this year.

there's a nice pic :D

Re: 80/20 ?!?!?!
 

We cant find any the size we want. Were looking for something like .5 x 1 or .75 x 1.5. Ive looked through a couple catalogs but cant find any that small. smallest piece with the same ratio are 1x2 and thats too big and heavy.

Re: 80/20 ?!?!?!
 

We have scrap bins full of the stuff at Bosch. We use it for everything but framing.

Re: 80/20 ?!?!?!
 

I would hope that Bosch doesn't have bins and bins of 80/20, as they are a direct competitor. I assume it's Bosch-Rexroth aluminum framing.

Re: 80/20 ?!?!?!
 

We have loads of 80/20 lying around that was either cannibalized from the pre-kitbot robots or just extra from those same years. Usually, some makes it into the robot somehow (mounts, standoffs, etc), but we usually don't plan to do it. Last year, for example, we made our electronics cover out of 1/8" polycarbonate and 80/20 (well, actually it was 20mm Bosch, but they're essentially the same thing); we did not plan this, it was just the most convenient material to do it with (although, in retrospect, we could have just bent and riveted the polycarb). So, while I have no doubt that there will be some 80/20 on the 2008 machine, I don't know where yet.

Re: 80/20 ?!?!?!
 

Yeah, that's it. We just call it FMS. http://tbn0.google.com/images?q=tbn:...ges/struts.gif

Re: 80/20 ?!?!?!
 

how easy is it to work with the 80/20 stock? do you use all the special bearings and brackets and mounts ect? Or just fab something up for it? And anyone have success tig-ing it?

Re: 80/20 ?!?!?!
 

Our team is trying something different this year. We used the kit frame the last couple years. This year we are making the frame out of 8020 quick frame and EZ-Tube connectors. We pounded our frame together on Saturday. Was nice not to have to deal with the bolts.

Re: 80/20 ?!?!?!
 

It has a clear anodize on it, so you'd need to get rid of that before welding.

Re: 80/20 ?!?!?!
 

1618's never used it before, save for one odd piece of what appears to be Bosch on the back of their 2006 robot, but it looks like we're going to use a good bit this year. Exact details are a known unknown, but the past is very much coming back to haunt me.

Re: 80/20 ?!?!?!
 

675 is.

For like the first time... ever since I can remember being on the team.

Although admittedly, it's a REALLY cool application of the material, imo.

Re: 80/20 ?!?!?!
 

Its very easy. We use some of the official brackets, but we make most of our own - its MUCH cheaper to make your own. 80/20 isn't the cheapest material!:ahh: We only use 80/20 in limited applications. It's kinda heavy to build an antire robot out of (and expensive). Also, 80/20 frames tend to twist and loose their square.

In 2007 We used four pieces of 80/20 1010 in our drivetrain. It made tensioning the chains really easy. We'll be doing that again this year...

I've also had good luck TIG-ing it. You just need to REALLY sand it down and make sure all the anodization has been removed. Otherwise you won't get any penetration.

Re: 80/20 ?!?!?!
 

You could look at the 1050 profile. It is 1"x0.5" but only has the t-slot on one side.

Re: 80/20 ?!?!?!
 

80/20 is great, great stuff. Just make sure you get the right stuff - some of it can be very heavy. We used it for pieces of our arm, our control board, motor mounts, and pieces of our chassis last year. It's really versatile stuff, I especially like the t-nut system. You can mount something virtually anywhere in the slot in a matter of seconds, no drilling, tapping, or any of that stuff.

Re: 80/20 ?!?!?!
 

I know my team is defiantly using it because our limited resources in a shop and on my old team we usually found 80/20 to be incredibly lighter than we throught and we used a lot of it for the arm, mast, chassis, well just about the entire robot. 80/20 is difficult to use for the inexperience but once you know how to manipulate it, it's amazing stuff.

Re: 80/20 ?!?!?!
 

1619 used it for our robot carrier when we built it. ;)

Re: 80/20 ?!?!?!
 

team 1591. god that stuff is great

Re: 80/20 ?!?!?!
 

We've had bad experiences with it falling apart every year, even when it's not a component that does anything. We have ALWAYS had to drill through it and run a bolt to get it to stop sliding.

Since it's difficult to drill through 80/20, we WOULD be better of using something else, it would just save us work! Our mentor, though, swears by the stuff because of it's modular nature. It doesn't become so modular once it's bolted into place. He's never around during that part :P

So my final opinion: Prototyping, maybe. Final build, no way.

Re: 80/20 ?!?!?!
 

We used it to biuld a multimedia educational display/pit display with rolling tool carts, media module, and safety module. It fits in a 10x10 and 8x8 pit. It has couple TV's and digital projector that projects onto a 10 foot tall back panel. We haven't had it at a competition yet as we are still working on getting the tool carts and other modules outfitted.

Re: 80/20 ?!?!?!
 

Team 1261. We use it every year for pretty much our whole robot. If you tap the end and use the cube-like gussets, as opposed to using normal gussets it shouldn't slip at all.

Re: 80/20 ?!?!?!
 

I've been looking around and haven't been able to find this so I was wondering if anyone knows what the weight comparison is between 1" x 1" 80/20 and 1" x 1" aluminum square tubing with either 1/16" or 1/8" wall thicknesses.

Re: 80/20 ?!?!?!
 

The entire 8020 catalog is on line and they have weight, tesile strength, etc all in there for both 1010 and 1" tubing ... http://www.8020inc.net/

1010 = .5097 lbs/ft pg 4
1x1 square tubing, .125 thich = .516 lbs/ft pg 81

Re: 80/20 ?!?!?!
 

We have never used it, not quite sure why but probably because we can buy aluminum angle, square tubing, round tubing, etc locally along with pop rivets and bolts and nuts.

Seems to me that the more universal a part is, the less likely it is to be "just right" for anything.

Re: 80/20 ?!?!?!
 

Hahahahahahahaha!!! Oh man.. that just made my day... lol :cool:

Btw, 80/20 1" "square" 1010 series has a hole in the middle of it as you may have noticed.

This is the perfect size to tap a hole for a 1/4-20 screw into.
That's usually the job the freshmen on the team get when they want an intro to manufacturing.
It's a simple task, and a prerequisite on our team to know how to tap those before moving onto more difficult tasks.

Re: 80/20 ?!?!?!
 

Sometimes people call it '80% of what you want for 20% of the effort'.

It's a system of extruded aluminum and fasteners that allow for quick and easy modifications. Attaching pieces of it together requires, typically, no more then hand tools.

The down sides are typical to any sort of modular building kit; Cost and weight. It's not cheap, and the fasteners aren't either. Because of the shape of the extrusion required to make the fasteners easy to use it's heavy for it's size.

It's a pretty high price to pay for the ease it offers. But a lot of rookie teams make use of it because you can toss a frame together with nothing more then a hacksaw and a wrench. If you don't have much in the way of tooling, or experience with frame building, it can be a godsend. Otherwise more traditional extrusions and fasteners offer much more.

Re: 80/20 ?!?!?!
 

Where can you order 80/20 from?

Re: 80/20 ?!?!?!
 

Ues this link to find a disributor near you. Tell them what you need and they'll send you a quote. Then you can send in your quote and get the parts in a matter of days.

If you want to order online, there is an Ebay-store that carries it.

Re: 80/20 ?!?!?!
 

We're using 80/20 this year for a elevator and with the linear motion slides they sell the whole system was easy to build and rather simple and doesn't weigh too much

Re: 80/20 ?!?!?!
 

We have substituted our Bible with an 80/20 catalog.

Re: 80/20 ?!?!?!
 

You can get some pretty good deals at http://stores.ebay.com/8020-Inc-Garage-Sale

Some of the stuff is auctioned (like 1010 extrusion), others items (like fastener hardware) is "Buy it Now".

You can save quite a bit of money through this e-bay seller. Don't forget to use the normal retail price when you do you cost accounting for the robot BOM.

Re: 80/20 ?!?!?!
 

what is 80/20?

Re: 80/20 ?!?!?!
 

It's structural extruded aluminum with special fasteners (like "drop-in" nuts) that can simplify building the chassis and other portions of the robot.

Team 980 has used 80/20 1010 extrusion for the chassis for years. It may be more expensive that square extrusion, but the strength/weight ratio and ease of assembly more than justifies the extra cost. This year, I purchased the 1010 stock for our robots on e-bay at a substantially lower price than what you'd pay at distributors. See my post above for more info (post #40).

BTW, before posting in CD, you should at least read the thread in which you're asking questions. Please read posts #11 (photo of 80/20 extrusion attached) and #35.
