WTF!? This is cool as shit! Problem still is there is no individual sensor per feather or way to rotate the feathers to properly mimic the flight of a bird. A bird can feel each feather and move it to adjust it's flight path. We can't make that and won't be able to for a while. I feel like it is going to be a hydraulic system rather than servos or steppers/etc, but will need the machine learning/AI to control it all.
