I admire the hard work that surely went into this, but I have to say: as a former robotics hobbyist, I'm extremely unimpressed with the weight, cost, and limited capabilities of this thing. And that impression is based on the technology we had over a decade ago. With access to a few machine tools and a 3d printer, I'd bet an equally capable prototype would cost no more than a few hundred dollars. No wonder almost no one has a robot in their home.
