I'm posting this actually quite a ways into the project. I started working on it around March-ish 2019, about the time that the final collapse of TheShop.build(nee' TechShop) happened and I lost access to a metal shop within a reasonable drive of SF.
So, here we are. My as-yet-unnamed SAWPPY-alike has now been moved to Circuit Launch in Oakland, CA. where I am one of their Roboticists in Residence, focusing on rovers and off-road, ruggedized robots.
Anyway, here are a few random pics of my build process. My rover was printed on a Raise3D N2+. The wheels are PETG-CF from Matterhackers. The drive axles and steering shafts are NylonX(About which I'll write more later) . The rest of it is printed in PETG from a variety of suppliers.
All great projects start out on the kitchen table:
The all-important mechanical "backpack test", when it was still occupying whatever random corner in our apartment I could put it in that night.
I spent (and am just now finishing) a LOT of time on the wiring. I've built enough robots of significant size to know that organizing and "dressing" your cable runs will save a lot of debug time later.
