Wow you guys are quick with your decisions, huh?

This is fiber glass profiles, right?
(If I remember correctly from your overdrive chassis)

Regarding the cheesing: arn't you cutting a little close (literally...)?

the space between those holes seems very very thin!

I saw the chassis sitting on the work bench last night on the webcast

This will be fun to watch progress on! hopefully we'll take a break from watching, and work on our design

Have you fully planned everything in CAD with your robot at this point?

The reason I ask this, is because swiss-cheesing a robot at this early in the game without knowing what will be mounted on it along the way is not the best of ideas imho.

We've prematurely swiss-cheesed chassis other years, only to have a nice hole right where we want to mount something.

CAD planning can help avoid that, but since most team's don't use that to it's full potential, swiss-cheesing at the last week, as opposed to the first week, is probably the best way to go.

Just wondering why you chose to make so many holes so soon.

We mount everything on the 1 inch lip, nothing will go on the cheese sides. We could still screw up though, we are crossing our fingers

Me and my brother (GUI) were wondering if you thought about bumpers for the front(?) two corners? We rechecked the rules on bumpers; <R08> A requires each segment to be at least 6" long, <R08> I requires all exterior corners to have bumpers, and <R08> M says the entire length of the bumper needs to be supported by the robot structure. I can't tell exactly what's going on there, so you may want to recheck those ones

Other than that, that's one beast frame! I love the cheese-holing job! Is there a specific reason you kept the long and narrow orientation of the drive train?

so if 10lbs is gone, how much weight is left?

[falconmaster]

14lbs

We will have to double check the rules on bumpers....I guess we could redesign to make a point instead of the little square ends

we wanted the wheels further up to the front, but we need to turn them and that would interfere with our ball retrieving from the floor. So we moved them back so the wheel footprint is a square.

Awesome frame! I have long been trying to convince my team to do a fiber glass frame. 1 point however, using idler wheels (as it appears you will on the front) will take weight away from your drive wheels reducing your friction that could help you accelerate.

1726's robot in 2006 had similar construction, with much more material removed than this (40 bs overweight three days before ship...), and it held up fine. I also believe the cheesing pattern on that bot was a bit weaker than this.

[Donut]

A nice looking robot as usual from 842. I expect to see a similar chassis design in many of the effective scorers at AZ (and everywhere) this year.

Now I have to ponder, what goes on top of this?
