Actually that's a good point, my brain was kinda stuck in thinking of things as an inverse kinematic problem, but if you're working with forward kinematics like he is, relative position isn't really an issue, rotational accuracy is, and I'd assume that data is far more reliable than judging distance with IMUs, it might just be a far more solvable problem than I thought.

I'd certainly love for there to finally be a cheap, reliable FBT solution I can point people at.
