Here’s some posing with steering angles… stylish lil guy eg?

Let’s add the computer, battery and soft assemble the partial wire harness (battery and servos connected; drive motors not yet… will add 2x6= 12 more wires/4 more cables to this picture).

Let’s power it up 😎
This is just led blinky running but it’s still neat. I got much further today than I expected. Now for toughest part… rest of wire harness. Unfortunately crimping and/or soldering may be needed and I suck at both.
Then the hellish challenge: programming

Back to the mechanical design of the main rover... just spent 2 hours figuring out how to get a mcmaster-carr ball joint and some standard nuts and bolts into my assembly, and detected some geometry issues that would have been annoying to discover after printing...

Finally actually earning the mechanical engineering degree they gave me in 1997. I think the mechanical design is now about 60% done. I'm now aiming to build a model accurate enough to simulate.

Turnbuckles and bogies need to be added, then the 4 drive units and 2 passive wheels. Another couple of days to rough it out, then 2 more to get all the finicky details doubled checked before I start printing.

Another good day. Design is finally roughed out. Lots of the dimensions and stuff are tolerances, but now I have something I can refine.

Especially proud of learning to integrate components from other sources properly. SG-90 servo motors are now in the design (random open-source), as well as a ball joint from McMaster-Carr

I'm still astounded by how I can do all this insanely powerful engineering design work for free, and my only cost is materials and time.
