Been following the claimed advances in the Kuri home robot, which now says it includes facial recognition and reaction. See their March Newsletter. Also will have IFTTT support, which should be very useful for other goal areas, like home security. Available for preorder, but no specific availability date yet. Had been considering testing this directly, but will likely await early hands-on reviews at the $700 price. I think ultimately there will be home companion/assistant robotics of this type.
