Aside from the occasional demonstration to prove the PID controller worked, the aluminum board hadn’t seen much action until yesterday, when I nearly drove the wheels off the little guy. An hour and 200 yards later, vibrations threatened to shake everything apart. The aluminum frame had bent into this:
I love this project. Even though the wrecked frame guaranteed a complete structural overhaul, I’m still excited to get back to work.
My friend D.G. and I worked out this sturdy alternative after a few hours. We temporarily mounted the new frame onto some plywood and re-attached the wheels / axle.
It’s coming together better than I expected. All the measurements line up frighteningly well.
Now to add the rest and clean up that deck!
