Here are some pictures of the prototype. I don't have any good pictures of the in-season chassis, plus it's painted black and hard to see detail on.
The four pictures are:
-Gearbox assembled, upside down. Secured to chassis inner on front face and bottom flange with bolts, significant structure to chassis inner. Secured to chassis outer with four bolts/spacers on front face, bolts on bottom flange to chassis outer flange. I'm not sure we actually bolted the gearbox outer to chassis outer on the bottom flange, we might have thought the four bolts were enough.
-Gearbox assembled, another view. It's just an AM shifter with 22t output sprockets and new plates. Prototype was servo shifted, production was pneumatically shifted.
-Prototype chassis assembled, with electronics tray and servo shifters. This later saw the bandsaw and became the practice robot chassis (we literally removed the rear chains and bandsawed it to 27" long). Talons also tested, performed admirably without fans.
-Chassis inner assembly without chassis outers or ends. Gearbox inner plates temporarily put in for fit-up, not yet folded. The top hat above the gearbox does very little, almost all of the loads in that area go through the gearbox. In fact, it's the only thing that bridges the inner and outer chassis in the middle of the span.
There were a few changes between this chassis and the production one, mostly in ride height (added 1/4" ride height) and chain tensioning (slotted all 6 wheels instead of only inner wheels). we also moved the battery for cg and placed the arm gearbox in the battery space.
