droid
     
         (From "android") The robots of the Star Wars
        universe.  While androids look somewhat human-like, Star Wars'
        droids are typically fashioned in the likeness of their
        creators or in a utilitarian design that stresses function
        over appearance.  Droids are equipped with artificial
        intelligence, though some are naturally created smarter than
        others depending on the function they are designed to serve.
     
        "Droid" is a Lucasfilm Ltd. trademark.
