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?

Re: Interesting material usage?
 

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.

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

Re: Interesting material usage?
 

Our team is using a bike rim that holds the ball in the catapult, paint brushes to ensure a smooth intake with little to no bouncing around, and a rubber duck for safety on our robot.

I got a tour of 131's robot in Boston last weekend, and they are using 3/4" thick PVC foam board as their shooter material. This stuff is light and strong, and they even bored out 1.125" diameter bearing holes in the plates.

Although I haven't been able to figure out for sure what it is yet, 469 has been using this really amazing green material for their intake rollers for the past couple years. While I haven't been able to pinpoint it's exact origin yet, sources point to it coming from Sweden.

Perhaps someone from 469 can pipe up?
