pic: Bit Buckets 2015 Offseason Drivetrain

We worked more on assembly and wiring today. Photos soon to come.

We do have two exciting documents to share: the CAD model and our engineering journal.

The CAD model posted contains a few bugs that we fixed with a drill and jigsaw, but is still a basically functional drivetrain:

The engineering journal is a description of our process and decisions in building this project. It is not an exhaustive document, nor is it a particularly polished one, but it will contain helpful ideas for designing things with plywood:

Have fun and feel free to ask any questions.

Pretty!

I hope you have a chance to bash this bot up in some open field defense. I'd really like to see how the plywood base holds up compared to, say, and AM14U, given that yours has much more cross-bracing. If it works OK it could be a really cheap way to design custom chassis (cheaper than laser cutting and bending aluminum anyway)

Latest iteration looks great! Get some bumpers and weight and drive it like you stole it.

I got to see the previous one (in the car crushing video) in person. It's an extremely clever design that somehow ranks high in all of the desirable categories; extremely stiff, relatively lightweight, and can literally be cut out and assembled in an afternoon out of $50 worth of material. The drop-out wheel modules are pretty neat too, I don't think I've seen something done quite like that before.

Great prototype, I can't wait to see you apply these design concepts to the rest of your robot this season. Might be my new favorite build material.

It appears that some parts were not saved in the same place as the rest of the project and were left behind when put on grabcad. Most of these parts are spacers and things that are not important

What parts are missing for you?

I just looked over the GrabCAD model and it looks like everything is there. I used SolidWorks Pack and Go, so it should have captured all of the parts regardless of location.

This is the message I got. I looked through the folder and couldn't find the part.

I re-uploaded the model; try downloading again.

Is it just me or did the Download All button go missing. I now have to download all of the files individually.

Missing for me too. That's odd.

Could it be a setting in the project?

I don't see anything.
