Interesting material usage?

We used a piece of hydraulic hose as the flexible shaft on our 270 degree intake roller. We used aluminum rod inserts for added rigidity for the sections that required it, but allowed for the durable flexibility at the corners. It performs admirably.

I found a picture of the robot built mainly from corrugated cardboard. The photo is really large so here is a link. You can see the cardboard frame behind the bumpers.

That's really neat!

here's the picture cropped...

How'd it hold up?

Very well, that picture is from their second event. However they did have at least one back up chassis with the manipulator frame just in case.

We clamped a smallish 10lb machine vice to our robot last year.

Since the climber never came to, we had spare weight and a higher CoG, so the vice was clamped to a section of our 1" tubing frame, with some zipties for "insurance" to adjust the CoG both forwards and downwards.

We have large catcher panels that are filled with sandwich bags containing polyester beads. The beads absorb some of the force from a long range catch.

I don't think anyone is going to beat 5259 on that one, they used a sombrero and a leg on their robot https://www.facebook.com/photo.php?v=10152207162797025

Team 5338 - Robo LoCo used blanks for aluminum levels (essentially I beams) on their robot this year

Can't remember the number but there is another team in our area that likes to try to incorporate a ladder into their robots each year. I know they've done it for at least the past two years.

1058 had a frame made out of I-beams and an intake made of clear PVC with LEDs inside of it.

Our robot's shooter is a 5lb dumbbell strapped to a swinging arm.

Artificial Decking material. We made our (rather ineffectual) pickup arms out of this. It's strong(ish) and light. I also saw a robot with a hockey stick and arrow shooter.

And it is very cool

Not sure anyone uses more wood than 58

Team 2485 wrapped our 1/16 wall aluminum in carbon fiber to retain yield strength while saving weight; it turned out to be a good call when we weighed in at 120.0 in Vegas.
We also used Kevlar in places where we anticipated impact; it's flexible, and we figured it could absorb some of the impact.

Here's a photo of our bot; both the carbon-wrapped aluminum and the Kevlar are immediately noticeable. It's nice that black and gold are our team colors too... plus carbon fiber has been a bit of a signature of ours since 2011.
