Welcome to another YAP (Yet Another Project)
This time it’s a self balancing robot…
I was researching STM32 stuff (blame @Jarrett) and stumbled onto an interesting site…
While not STM32 based the balancing robot caught my interest mainly cuz I had a bunch of the needed parts gathering dust… So I decided to build one and figured I’d document the process here.
The one thing I did not have was the wheels. In the project he is using laser cut plywood to make them but I sort of wanted something better. I spent a lot of time searching AliExpress. I wanted a similar size (2ish inches) but with decent rubber… I also had to find something that would easily mount on the 5mm stepper shafts. While not really as cheap as I’d like I found these and ordered a set:
Since I had to wait for the wheels I went about gathering the parts I did have and figuring out what size board I would need.
Looks like a 7cm x 9cm proto will do the trick and luckily I had one.
One thing I was missing was the radio transceiver module. Looked around and ordered a couple of these as I had seen them used in some other projects:
Next I thought about the frame. They used plywood for the prototype but I didn’t have any thin stuff to use. But I do have lots of aluminum angle so I decided to use it. I’m wondering if it will affect the rf signal but it will just be a frame so there will be lots of open area.
