That's a very cool looking frame :cool: Not sure as to its practicality, but I like the roundedness of it. Very slick indeed.

What kinda paint did you use? The blue adds a nice touch.

Re: Is your frame tough enough for FIRST?
 

Hachiban, we used Rustoleum metal finish paint. You can get it in almost any color at your local hardware store. As for durability, our unibody survived being flipped over twice, being rammed by another alliance, and being slammed around in a truck bed on the way to the WPI Battlecry off-season event without any dents and just minor wearing off of the pretty blue paint. Also, being 14.1 pounds underweight with the battery installed is a pretty useful feature. The only caveat is all of the riveting we had to do to attach the skin.

I might suggest you get a new scale :cool:

CIM = 4(2.75)
Battery = 13 +/-

Total = 20 +/-

Unless of course you're hiding some baloons in there...

a lot of baloons...

You should've seen the mayhem reeked on our copper pipe game layer... Not pretty.

The benefit of using the unibody is that because the skin acts as a frame it is quite a bit lighter than the standard frame design. We actually had to bolt on a 14.1 pound steel plate onto the chassis to stop the bot from flipping over in high gear. Also on the bottom of the chassis we have many, many flanged holes.

Makes sense to me, he said 14.1 lbs underweight.... Not 14.1 lbs.

Oh, my bad. I appear to have been confuzled

srsly u guys

Re: Is your frame tough enough for FIRST?
 

Well...

A lot of people might be quick to put off plywood as a chassis material. However, depending on the plywood, it can be tough stuff. Our plywood chassis have survived everything from stack attack to overdrive, and all of the robots in between still live to today. Worst hits that I have seen a robot of ours take was a wall, and another robot, at 17-20 fps during hybrid. These robots did have bumpers (some of them), yet they still have surprising durability, in that they have survived some tough pushing games, and tipping.

I guess if you want more proof that plywood's strong enough for whatever FIRST throws at us, ask someone on RAGE. I hear they've made some pretty successful wooden bots...

I forget the name but a team based out of L.A. built their robot's frame out of bamboo which is incredibly strong and lighter than aluminum.

Also bamboo is the also used in baseball bats, a lot better than aluminum. Nice way to use bamboo, any pics?
