The term "droid", popularized by George Lucas in the original "Star Wars" film and now used widely within science fiction, originated as an abridgment of "android", but has been used by Lucas and others to mean any robot, including distinctly non-human form machines like R2-D2. The word "android" was used in "" episode "What Are Little Girls Made Of?" The abbreviation "andy", coined as a pejorative by writer Philip K. Dick in his novel "Do Androids Dream of Electric Sheep?", has seen some further usage, such as within the TV series "Total Recall 2070".
