Where's That Robot Housekeeper?

Sitting around the table after supper the other night the questions arose: "Dude, where is my flying car? Where is my jetpack?" And when it came time to clear the dishes, "Where's my robot housemaid?"

I could say why we have no flying cars (air traffic control nightmare) and no jetpacks (ditto). But how come we don't have household robots yet? I mentioned Roomba, the robot vacuum cleaner, and the problem of rogue robots, but noooo. My family and friends want their very own C3PO. Had I seen this article sooner, I could have given them at least a peek at the future and a timeline:

"South Korea predicts that every home in its country will include a robot by 2020. Unlike industrial robots that toil in structured settings performing repetitive tasks, these “Next Generation Robots” will have relative autonomy, working in ambiguous human-centered environments, such as nursing homes and offices. Before hordes of these robots hit the ground running, regulators are trying to figure out how to address the safety and legal issues that are expected to occur when an entity that is definitely not human but more than machine begins to infiltrate our everyday lives."
