Intel’s HERB (Home Exploring Robot Butler) might come with metal fingers, but it could possibly have green fingers if programmed properly. This unique robot is able to explore your home, sporting the necessary intelligence to pay bills, serve dinner, clear the table and even do the dishes, which means it is waterproof to a certain extent, at least for its hands. HERB is still a wee bit slow for everyday use, although he is quick enough to catch on by visually identify items which his human masters may want. Great to have him around bring you beer after beer during the World Cup season, eh?
