Here is a chassis I designed using solidworks.

Gen2 Andymark transmissions
6WD (IFI 6" diameter 1.5" wide)
0.09" sheetmetal (possible to change to between 2mm-3mm)
0.75" flanges for structural support
Weighs about 25lbs Without electronics
Direct drive to middle wheel

Any Tips or Questions?

self taught right?

[roboticsgoof95]

lol not in a bad way.. its sweet.

[Chris is me]

Do you have access to sheetmetal resources, or is this a for fun thing?

My dad's company has a water-jet machine (they are our biggest sponsor, higher than GM), and he also told me that we could get it laser cut, from a different company. we are planning on building it before kick-off, to prepare grade 9's and other new students.

These tools are great but without a way of bending the sheet you will be up a creek without a paddle. I think (actually, I know) what Pinecone is trying to say is: "Are you designing to your resources?" For example, if you have welding capabilities in house but have to send out parts to be laser cut there is a serious benefit to designing predominantly with welded tube. The key here is iteration and if you can iterate more using tube you will come out with a better product in the end.


(The above is general advice, not being familiar with the OP's team's resources it is there purely for the sake of it being said.)

We have all of those resources. Their shop has sheet metal benders but so does our school. We were deciding if we wanted to rivet the chassis together or weld it. The laser cut is not a definite thing, we can either get them laser cut or water-jetted. either way i would be able to give them the print in the morning and by the end of school we would have chassis parts

The company builds the assembly lines for cars, so they have alot of different machines, its not just a little specialty shop for welding or sheet metal.

EDIT: we did a tube chassis last year that they welded for us, we are gonna try this one for the offseason and if it doesnt work as well (resource wise) we can go back to tube chassis.

Post up a higher resolution picture please. I think I see a few issues with the frame, but don't want to comment unless I can confirm with a closer look. A lighter background would be nice as well.
