Neat stuff, it's fun to try to piece together a design with only a few of the pieces shown. I'm assuming from the odd bearing sizes and frame gussets that this is some kind of drivetrain with rotating wheel modules, but I can't figure out how your previously posted gears and pneumatic cylinders fit in. My money is on some bizarre type of shifting approach for transmissions that will drive coaxial modules, but I wouldn't be surprised if it's something even more off-the-wall.

I anticipate the full reveal, looks fun! .stp file would be appreciated of course.
