PVC Frame

[sportzkrazzy]

That is true when used in the proper way. I just don't think that it could withstand the stresses of being used as a frame. I suposed if you truss it correctly then all will be fine but won't it bend, flex, or maybe even break when crashing into another bot?

That is true. Depending on where it is used as a frame, of course-- if it's simply a cage to keep soccer balls out, it's probably going to be fine for most matches. If it's the drive chassis, you probably want to rethink the design.

Even some of the big stuff can flex. I think the best way to demonstrate this is to hang a robot off a piece of 2" (or was it 3"?) PVC that's about 4-5 feet long and supported only at the ends. It'll flex. I've seen it. But it didn't break.

Let me add to my previous post...

You say "the right application" which I completely agree with. 1279 has used pvc every year since our inception. I think PVC cement is allowed since there aren't many restrictions on adhesives anymore. (I wonder if cement was restricted before adhesives were allowed... *thinks back*... o well) PVC robot chassis would be the first I have seen. But hey, prove us wrong.. and send me some sweet pics if you do it.

Ok then we are on the same page. Lol sory about that had to make sure.

If you are going to use PVC, I would suggest you talk to 1058, the PVC Pirates. This team uses PVC in some unique way on their robot every year. I am always amazed at their creative use of the material, and the durability of their robot.

One thing to consider is using ABS instead of PVC. ABS is less brittle than PVC which means it will tend to bend in situations where PVC would break. For more info about the pros and cons of both ABS and PVC check out this link

Its not exactly the same application (spud guns vs robots) but the info is still good

Hope this helps'
