"You're just a droid. You don't know about real duty, about what it's like to have a brother." "I am sorry. I always wanted to have human feelings, but I do not."
―Clone trooper Fives and AZI-3
Protocol droid C-3PO, and astromech droids BB-8 and R2-D2 Droids, less commonly known as robots and automatons, were mechanical beings that possessed artificial intelligence. They were used in a variety of roles and environments, often those considered too menial or too dangerous for other species, but also in fields that required extensive specialization and knowledge.
