First metal… cut 100mm strut.is there any use for aluminum filings? Saving it anyway. 9 more to go. Aluminum is much softer than mild steel, but hacksawing it is still a bit of a workout. Needs some filing

Ok that was really quick. 5 minutes for 3 cuts. Takes some control though. The cutting disc wanders easily. And aluminum stock does get hot.

Two rocker bogie sub assemblies almost done. Waiting for drill to charge so I can make the pin joint holes larger so these binding posts fit. Took a bunch of filing but I have a nice snug fit.

Ugh this was a bitch to do. Tiny M2 mounting screws for SG90 in misdesigned casing, servo horn on bracket, N20 in fork. But good news, the conduit theory of wiring is probably going to work out though it’s gonna be a tight fit.

😬😬 partial assembly holds together. Now question is if it will hold together when all the wheel assemblies are in.

I can already see that this is going to fold like a cheap tent without very significant modifications. The ball joints have too much freedom and the wheels too narrow. But hey that’s why we prototype. Let’s clean this up for a break. Lots of progress today.

MAJOR MILESTONE! First mechanical test assembly! Janky as hell and awful in a hundred ways but it doesn’t entirely collapse!

Okay, here we go again. I’m supposed to do a build update on Monday and have done nothing since December so the goal is to do a short heavy lift to show some progress, any progress… just spent half an hour figuring out how to connect to the rover over WiFi 😬

My own documentation sucks and so does the official documentation but eventually figured it out and got back to the starting line of blinky

Whew and woohoo… after 12 painful solder joins of 28 awg delicate wire, ABTF is finally rigged and running. Need to get the heat shrink on, add some cable ties, secure the motors better… and finally get to programming

Really bad solder joins. Lumps on some that prevent the heat shrinks from sliding on. Shoulda known and used bigger ones. I need an Igor. Or just a young lab assistant with better eyesight and better dexterity.
