Kiva is not quite what you seem to think it is. Those robots navigate in specially constructed, human-free, spaces with QR codes on the floor to keep them positioned right. It is a highly developed system, but not one designed for anything remotely like a human home. And I would separate your #3 into two items: recognizing household objects (a very significant bit of work), and then interacting with individual objects. Single instances of each of those are tasks that whole companies are devoted to. General-case systems are just not in the cards at this point.
