According to research conducted at the Eötvös University (Hungary), dogs have the same issues with robot dogs that people have with robots that look like humans... see my last post. The questions being asked by researchers are "what is the influence on the dog's reactions of movement, smell, presence or absence of eyes, sounds, etc.". Looks like the eyes are an issue for the dogs too! Could also be that the AIBO is trying to steal his lunch!
