looks verrrry heavy...

it seem too heavy

How heavy is heavy? With gearboxes, motors, electronics, the calculated weight is 50lb...

And I can lift this with one arm. Easier to lift with two arms..

For sake of comparison our chassis with 4 CIMs, mechanum wheels and all 4 gear boxes is less than 35 pounds...
For what it's worth, we've gone the 80/20 route. While it's great for prototyping and testing, we've found it's far too heavy for competition use. We've since switched to welded thin-wall steel tubing and it seems to work quite well.

It does look a bit heavy, But it also looks very strong! Good work from team 3082 (Minnetonka)! I can't wait to see this at 10,000 Lakes! What drive train are you using? It looks like it could be a swerve...Well I gues I will see in two months

Nice chassis. One of the coolest uses of extrusion I've seen so far. Though that's not saying much. That's a lot of material, but it's material fairly low, which should be good for your CoG.

I'm intrigued with the wide orientation. Can't wait to see the rest of it, so I know why you guys took that route.

It depends on what the rest of the robot needs in terms of weight. 70 pounds is more than plenty for what they plan on doing, as far as I've heard their plans.

Trust us you'll be surprised how weight seems to adds up... fair warning just make sure you are careful how heavy the rest of your robots functions are.

calculated weight do you know how heavy it actually is or have you not weighed it yet?

Most of the parts he named aren't on the robot yet, so it's hard to weigh the final configuration.

50lbs with all electronics is plenty light, I think. Personally aiming for a 70 pound lower deck / 110 pound robot.

well he could do what we did and just put the stuff on the scale with the chassis

[V_Chip]

Looking good

Interested on the wide base configuration

Some folks might not have a scale that will work for that.

[keehun]

I will weigh it this coming monday.

And we do have a very interesting wide-configuration that will be super weird but we hope to have work out!

And no swerve this year. We thought that whatever we could make would have too low of a clearance to go over the bump.

Hm, did I give too much away?
