Looks nice!

Of course I have to ask "How much does that weigh?"

Wish I could make it to Palmetto to see you guys compete.

What is the white compartment at the top made out of?
How overweight are you guys?

If it's any comfort, we hit 180. Two days later, 130. We started the Traverse City District Event at 105. By eliminations, we were at 119.9. Our driver blowing on the robot tipped the scale. =D

Re: pic: Right Round

the white hopper at the top is made out of corrogated plastic, or signboard (our teacher calls it chloroplast??) It's some funky shape cut out and folded, and held together by rivets.

Right now i think we were only overweight by 3 pounds. and we have two gearboxes that we've lightened and are planning to switch out quickley when we get to palmetto ext week.

Re: pic: Right Round

It's actually Coroplast http://www.coroplast.com sheet material. The "plastic cardboard" that is used to make yard signs and that sort of thing. Lightweight, stiff, fairly strong, easy to work with. You can get it (or something similar) from most industrial plastic suppliers, or smaller pieces from your local sign shop. There is a ready supply of it at the school because they make vinyl signs in the same room as the robot. We've used it for all sorts of things over the years: guards, hoppers, sponsor/number boards, and even used to use it to mount all the electronics. It's not stiff enough to mount a cRIO though. It comes in a bunch of colors, too.

Re: pic: Right Round

Depends on your thickness and support. It will support a cRIO if it will support a robot.

And yes, I have some pictures:

Team 330, 2007. Support: 1" thinwall aluminum tube on 4 sides, glued on, IIRC. Might also have a couple of bolts/rivets. Survived 1-2 regionals and up through Einstein semis, depending on exactly which panel. Also IRI and the Fall Classic, if I remember correctly. That stuff is tougher than you're giving it credit for. Just use a couple of largish washers when you put a bolt through so it doesn't collapse as badly as it would under a point load.
