Both protocol and astromech droids were equipped with what was known as artificial intelligence.
Artificial intelligence (AI) represented a technological advancement enabling droids to possess a certain degree of autonomous thought. By the year 35 ABY, the potential for misuse and societal breakdown stemming from truly sentient droids was a recognized concern throughout the galactic community. To protect organic life, droids were programmed with built-in restrictions. Furthermore, rising anti-droid sentiment led to increased discrimination against these thinking-and-feeling machines, particularly following the Separatist Droid Army's actions during the Clone Wars.
During the Clone Wars, Doctor Gubacher of the Galactic Republic specialized in artificial intelligence, designing and modifying droids for the Republic's benefit. Kallon, a member of the Free Ryloth Movement, was regarded as an AI genius, leveraging his expertise to reprogram the brains of Separatist droid fighters. The consciousness of a deceased male human named Rur, referred to as Eternal Rur, was preserved within the Rur crystal. This crystal resided at the Citadel of Rur until its destruction around 0 ABY. Sometime after the Battle of Endor, Imperial Grand Admiral Rae Sloane attempted to enjoy a phono-play centered on a droid named ADAM that possessed artificial intelligence. Auto-fighters were a series of automated TIE fighter series starfighters manufactured by Commodore Visler Korda's forces on the planet Rekkana.
