They published a video of the manufacturing that showed those CNC machines, injection molding, and robotic assembly. It's a lot faster to iterate if you have in-house machining and molding; you can get parts made or modified in <day vs weeks with an outside shop. You can also work closer with the machinists to iron out challenges.
