Putting the womb in the robot seems really retarted and overly complex. You would just have a pod in your living room and when the baby is ripe, you take it out of the vat. I mean you could still cum inside your robot, then she takes the fertilized egg out and puts it in the birth pod to start growing. And im sure there will be an attachment that makes her belly grow at the same rate as the baby in the vat. But all of that will be extra and seen as fetish shit.
