After a week and a half (!) delay in getting our metal, we're getting our chassis together. As pictured, about 36 pounds. There will be four more wheels in it when all's said and done, and the kicker will be actually mounted to something. 
Parts are there to visualize how it'll look in a few days time.
Still to be done, mount the kicker and ball magnet, mount the winch, mount the bumper frame... We're plodding along.

This looks like the start to a quite successful robot. It looks very similar albeit different material to our still virtual drivetrain. Couple questions...How thick is the aluminum? Given the scalloping along the bottom why did you not use smaller wheels?
Overall though this looks great!

Thanks!
The aluminum plates are 3/16".
We went with 6 inch wheels and scalloping just for extra security with bump clearance. Some people on the team wanted to use the 2008 KoP wheels due to budgeting concerns, so using 6 inch wheels would have been cheapest too. Now that we're using 6 Plactions, it's not cheapest, but it still works. I'm guessing based on the question you guys are using smaller wheels?

Yup we are actually going with 4.5" wheels with the scalloped chassis as well. We went the custom route though on wheels so the cost wasnt a problem.
Did you think about direct driving one of the wheels instead of chaining all of them as well?

Haha I love the east coast drive reference. We're doing dead axles too and wood frame again....Maybe that would be the down south drive.

Make sure that the kicker is well-filed so it doesn't harm the balls.

Chris,
What are the holes on the front of the kicker arms for?

I think the holes are left over from drilling at a slightly lower / crooked spot. Not exactly elegant, but it kinda sorta looks like weight reduction to me! Though now we're down to one mast instead of 2.
