Back when I built my ER1 robot, it's frame is constructed with what is know as XBeams (see the attachment for a picture). Evolution Robotics have discontinued the ER1 for now and have not shared the source of the XBeams and connectors http://www.evolution.com/er1/. I have searched the web with no luck at all, so I am again asking the robot world for so help. ANyone know were I can by these, they allow the build to be creative, kind a like an erector set but very strong.

Thanks again.

Shure looks like 80/20 stuff. they have a store on e-bay.

Feel free to post a link here in the forums. It won't ruffle any feathers here :)

You can also consider the lynxmotion system (http://www.trossenrobotics.com/store/c/2703-Lynxmotion.aspx) of tubes and hubs. It's the closest thing I can think of to the modularity of the ER1.

Now thats what I call service, jdolecki you are the best. I found the web site and it is just what I have been looking for. Evolution calls it XBeams so thats what I have been searching for (wrong name) the 80-20 beams(http://www.8020.net/) are great for building a strong but very light robot, stronger then the Lynxmotion stuff (however thanks Matt for the suggestion) if you want a robot than can run over ruff ground. Also with all the different connectors you can get very creative on the body. Thanks again, best regards

All I can say is wow:robotsurprised: This system is perfect for hobby level robotics!

When I first talked to you (tymtravler) about the "Xbeams", I had a hard time wrapping my head around the potential of these. Now that I've looked at the 80-20 catalog (click on the "Click Here To View" link on 8020's homepage), my thought is why don't we see more robots built with this stuff?!? My guess is that the price is really high and/or that the average hobbyists can't find a place to purchase quantities they are interested in...

That slogan is priceless: "The Industrial Erector Set".

Keep all of us posted with what you find out tymtravler!

Found out that the prices are not bad at all. I needed a 1"x1"x 97" beam and a living hinge, the beam was only $22 bucks and 4-6 bucks for the hinge ( mind you the hinge is not a cheap door hinge). I have found so many parts you can really go wide and still keep it in the budget. ALso you can go on Ebay to 8020s garage sale site and by scrap pieces and parts for less. I got just what I needed for half the cost because I did not need alot, here is the site. http://stores.ebay.com/8020-Inc-Garage-Sale

Awwww... I HATE this! Now I have a new supplier of parts! And I'll have to do redesigns and ... oh well, who needs a 401k anyway?
I'd seen this before but didn't price them out because ... I already had a supply of unused parts. Now that Otto is mostly constructed, I can begin designing Mega-Otto. After all, how will robots take over the world if we don't build them?
Did I mention I hate you? ;)

Love, Hate- does it really matter, hey as long as we keep building them better, someone has to take care of us in our old age. Better something we build and control, other than someone who tells us when to go to the bathroom. Also I found a great suppier for robot tracks, and I don't mean cheap plastic junk or snow blower stuff. If interested let me know, they will make whatever you want. They are making a track system like the HK tank, and I can afford it.

Did you say... TRACKS?!!!
I LOVE tracks! Well, Otto loves them. I just have to do whatever my robot tells me to do.
Definitely interested in reasonably priced tracks. Please post a link!
Now I'll really have to hock a kidney or something. Well, I've got a spare.

Well you asked for it , you got it. Here is the company that makes these custom timing belt, http://www.brecoflex.com/, they have a site that explains the applications they made for robot wars. Several of the tracks have a foam footing for travling over carpet and double tooth tracks for grass and dirt. They also have a program to create your track layout with all the different drive and idler wheels so you can see what your track system will look like. They have belts from 1" to 6" wide so depending on what vital organ you want to sell they can make it. Good luck and have fun making your drive system, I will post a picture as soon as I get it and put it together.

Another (much simpler) cheaper option is (depending on how big your robot is) to go with one of the Lynxmotion track kits. I have one, and I am totally impressed by the quality and the way it goes together.

You can either buy a full track kit (http://www.lynxmotion.com/Category.aspx?CategoryID=109) or the individual pieces (http://www.lynxmotion.com/Category.aspx?CategoryID=94) to roll your own...

Hey thanks for the info, I have already checked out the Lynxmotion track kit and have found that it is way under the load limit for my robot, mine is almost 75lbs and has a lot of hardware. Lynx is great don't get me wrong, I wish the arms they make were bigger and could at least pick up a full beer because the software for them works on several of the programming basics that I know.

The Lynxmotion tracks and sprockets themselves are quite capable of holding up a 100lb robot... Its just the hardware they are using with the track kit that can't handle any weight.
