The center of attention at the showroom currently is AIBO, Sony's autonomous entertainment robot. AIBO was introduced to the world as a dog-shaped robot, and subsequently newer versions modeled after other young animals have come out. Like a real creature, it changes its behavior depending on how a person interacts with it and has the ability to learn. More and more people are attracted by the comforting effect that the robotic pet, much like live ones, has on humans. AIBO's advantage over real pets is that it will always be its lovable self without ever having to be fed or walked, and this may be a major reason why it has become so popular with busy city dwellers.
