Hi!! I'm Karolina, and this is my project! Had no idea this got posted until someone DMed me about it on LinkedIn. Feel free to ask any questions or follow along via X (karolina_dubiel) Thanks so much for all the kind words, it means a lot!

This is very impressive! I researched fault-tolerant octorotor control using RL in grad school for a NASA project. Perhaps this may be helpful[1, see section 8.3]! The field is moving fast, so there may be better or more suitable approaches out there now. For folks who are interested in UAV physics, I wrote up an explainer[2].

Something I've wondered for octocopters - could using a ring instead of arms be beneficial for weight? 6.28r < 8r, but then again the arm radius is usually less than the full circle, and some components want to be centrally located, etc. I could imagine holding the central components in tension via light filaments (carbon fiber, nylon, etc) in tension, vs having to have rigid structure, but the small factor between 6.28 and 8 and maybe makes it not worth it.

I find it very hard to believe that someone who has never done any CAD could design that with Fusion 360 in a day. I do lots of 3D design with Fusion and there is a serious learning curve. It's not something you can pick up in a day. She is doubtless much smarter than me, but that's not credible.

Cool project! For a DIY beginner, what would be a good starting point for a "normal" drone/octocopter project?
