Robots are manufactured beings of sentience and are found in a wide variety of forms. When or where the universe's first robot was created is unknown, however many robots are designed and created on Earth. Many robots have the ability to transform themselves into new forms, often seemingly defying physics. They are not to be confused with Cyborgs, who are part organic.
Droids are usually more machine than being, possessing specific functionality and come in models[NeS1 1]. They're primarily based on droids from the Star Wars[Ext 1] franchise[Ext 2].
