My Full-Size B2EMO Build Has Begun!

Let's build a new full-size droid!
This marks the start of a new droid build. B2EMO as seen in the series Andor is one of the latest offerings from Michael Baddeley. Currently available to his Patrons, if you'd like to build one yourself, head over to his Patreon page to sign up: / posts
In this first part, I build the mostly metal base frame and make good headway on the four (!) drive units.
This build is different from R2D2 in many ways beyond the obvious physical differences. There are a lot of non-3D printed parts, the internal structure and mechanisms are separate from the skins and body panels, and once completed, B2 will be have a much more dynamic demeanor than our old buddy R2.
Electronics will be incorporated much earlier in this build, and I will be diving into the world of RC control for this one - a new arena for me and one that I have already begun researching.
I'll share my progress at various points along the build, and try to pass along what I learn on my journey. Hope you stick around - this one will be really cool when it's complete.
