Sony's puppy-sized robot dog Aibo, equipped with cameras, artificial intelligence and Internet capability, can now remotely check up on family members, children or even pets. The 30-centimeter robopup with flapping ears and cutting-edge LED eyes will roam around the home at pre-designated times looking for family members.
