A new self balancing robot

I started a new two-wheeled self-balancing robot project. I have built a few balancing robots before. This time, I want to make it even better. Trying out some new things while also making the robot even better documented and easier to replicate.

In this video, I make the chassis using 3D printed parts. The parts were sponsored by JLCPCB who 3D printed them for me. The parts are made out of PA-12 Nylon using MFJ 3D printing process. But those parts can also be printed using any standard filament printer you may have at home.

In later videos, I will make a PCB and show how I code and tune the robot. The robot will be remote-controlled, and also have an autonomous obstacle avoidance mode.

Here is a link to the 3D CAD files (Fustion360 files and STL files for 3D printing): http://brinkeby.se/downloads/2021%20Balancing%20Robot%203D%20CAD%20files.zip

The soft foam tires used are from RC plane wheels. I got them from this Swedish RC hobby shop: https://www.mbs-rcmodels.se/hjul/lattviktshjul-76mm-11g-2-pack/ I don’t think they ship outside of Sweden, or maybe they do. Maybe it is possible to find other tires that fit. I have also included STL files for the tires in the downloads if you want to try and print them out of TPU or similar.
