I'm developing my own QQD robotic actuator and plan to sell them if they're well-received. I was wondering what the biggest issues people have right now are. I know lower-cost and more reliable or cheaper options for FOC control would be nice, but is there anything else? Any personal experiences would be especially helpful.

Also, if you don't mind telling me your position, like if you're a student, hobbyist, or something else, just to contextualize it, that would be awesome!
