A NOTE ON NAMES
Russian names consist of three parts: the given name, the patronymic (derived from the father’s first name), and the family name. Often, individuals also go by a nickname. Hence the first character introduced is Stepan Arkadyich Oblonsky—Stepan is his given name, Arkadyich the patronymic, and Oblonsky the family name. But the man is often called “Stiva,” his nickname.
Class I and II robots also use a three-part nomenclature: a Roman numeral for class type, a function-designation, and an indication of model. Hence the I/Samovar/1(8) is a Class I device, designed to steep and serve tea, model number 1(8).
Class III robots are universally known by the nickname bestowed by their master or mistress.
