Top CES tech reveals include robot dogs, foldable television

Who let the dog out? Sony rolled out a much cuter -- and more sophisticated -- Aibo robot dog on Tuesday, and it came off acting and moving a lot more like a real canine. The Japanese electronics giant retired the original Aibo in 2006 and went back to the lab to develop a 2.0 version. The one displayed at CES 2018 here has a new design that features expressive LED eyes and a vastly expanded range of movement, and is able to learn new tricks through real-world training. It is currently available only in Japan, but for roughly $1,760 and perhaps a little web magic, you can be the coolest person at the neighborhood dog park.
