Androids and Gynoids (collectively just referred to as androids) are the robots who serves the members of the Royalty as bodyguards and servants. They (generally) look like typical human maids/butlers and serve many functions. All of the androids serving under the Royals are made by Frankenstein and communicate with their masters using various combinations of "Fuga" ("Huga" in anime), which is only understood by members of the Royalty and other androids. They would go to Frankenstein's mansion at regular intervals for maintenance.
