Cybot Galactica was a business specializing in the creation of droids, most memorably the 3PO series of protocol droids. These droids were made on the planet Affa, which served as their factory world. C-3PO, the well-known protocol droid, was constructed by Anakin Skywalker using discarded parts from Cybot Galactica droids found in a junkyard on Tatooine. In addition to protocol droids, Cybot Galactica also produced a number of medical droids, such as the 2R-series and the AZ-series, as well as analysis droids like the JN-66 and the SP-4.
Alongside Industrial Automaton, Cybot Galactica stood out as a prominent manufacturer of droids throughout the galaxy. Their success was largely due to the introduction of the 3PO series protocol droid, which revolutionized galactic interactions with the innovative TranLang III communication module. This module enabled fluency in over six million forms of communication, including both speech and vocalizations. Cybot Galactica operated from its manufacturing planet of Affa, where the 3PO units were assembled. The company further contributed to the Galactic Republic's war effort by designing various droids, including the IM-6 Battlefield Medical Droid and the IW-37 pincer loader droid, which was utilized by the Jedi Order's Eta-2 Actis-class interceptors. Following the rise of the Galactic Empire, CG continued to create droids for them, such as the AC1-series surveillance droid and the WSW Mk III "Harrier" Combat Remote.
The most well-known and oldest product from Cybot Galactica was their line of protocol droids, which began with the TC-series introduced before 32 BBY. These droids served as assistants and butlers for high-ranking individuals, including Nute Gunray, the Viceroy of the Trade Federation, whose aide TC-14 was one such model. CG improved upon this design with the 3PO-series, maintaining a similar appearance but incorporating the highly advanced TranLang III communications module. The 3PO droids also had more personality than the TC models, acting as pleasant, though sometimes irritating, companions. Despite efforts from Industrial Automaton and Arakyd Industries to gain market share with specialized models such as the BD10-series assay support droid and the RA-7 protocol droid, Cybot Galactica remained the dominant force in the galactic protocol droid market.
While primarily recognized for protocol droids, Cybot Galactica also made significant contributions to the field of medical droids. Among their products was the AZ-series surgical assistant droid, which served as an emergency medtech in the Galactic Republic's Kaminoan military facilities. These droids, known for their pleasant and curious demeanor typical of CG products, were equipped with a variety of useful tools such as fusioncutters and anesthesia inducers for operations, scomp links for computer navigation, and the ability to transform into a repulsorcraft for rapid transport. The Grand Army of the Republic also used another CG medical droid model, the IM-6 battlefield medical droid, which was standard equipment on Low Altitude Assault Transports and All Terrain Tactical Enforcers for treating combat injuries. Additionally, CG produced the 2R-series medical droid, but its failure led to the repurposing of its parts for the more successful RH-series research droid, widely used by the Alliance to Restore the Republic.
In addition to their more sophisticated droid models, Cybot Galactica also specialized in producing labor droids, which were autonomous drones designed for manual labor in military and civilian industries. The CLL-series was particularly prominent during the Clone Wars for the GAR, with the CLL-M2 binary loadlifter model used in military and naval installations to load cargo onto vehicles and transport starships. The IW-37 pincer loader was used for more delicate cargo in confined spaces, including the Eta-class starfighters of Jedi officers. Doctor Sionver Boll also modified some CLL units to study the Zillo Beast in its containment on Coruscant. Later, CG began manufacturing WED Treadwell repair droids, specialized maintenance droids for repairing turrets and combat units of the Galactic Empire.
For the private sector, CG produced PK- and SE-2 worker droids. The former saw use in the Lucrehulk-class LH-3210 cargo freighters of the Trade Federation, and later handled most support and repair tasks for the Droid Army of the Confederacy of Independent Systems. The SE-2, on the other hand, was more commonly used in remote settlements as a general service droid, earning it the nickname "farm droid".
A less publicized area of Cybot Galactica's operations was the production of analysis droids, specialized units designed to analyze objects and artifacts, tracing them back to their owner or manufacturer. These droids were popular among law enforcement and military organizations like the Coruscant Security Force and the Jedi Order. The Jedi Order used both SP-4 and JN-66 analysis droids in its Analysis Rooms. The Order even modified several SP-4 units into SP-4 ISCs to aid Jedi investigators in their cases, due to the Dark side of the Force obscuring their precognitive abilities. One of these modified droids, Russo-ISC, assisted Jedi Knight Anakin Skywalker and his Padawan Ahsoka Tano in identifying the perpetrator of the Bombing of the Jedi Temple hangar in 19 BBY.
After the formation of the Galactic Empire, Cybot Galactica continued to produce military droids for the new government, including the AC1-series surveillance droid, an intelligent spy droid programmed to report directly to Imperial officers, and the WSW Mk III "Harrier" Combat Remote, which was armed with twin repeating blasters and could be extremely dangerous when deployed in large numbers.
Due to the widespread presence of Cybot Galactica droids, many custom units were built based on their designs. A notable example is 0-0-0, which resulted from combining a 3PO-series chassis with the Triple-Zero protocol personality matrix. When properly executed, this combination modified the droid's hardware to include deadly weapons, such as subdermal electric pulsers in the palms and a proton charge in the chest, turning it into a sadistic assassin droid. 0-0-0 existed in various forms over the years, taking control of different droid bodies and causing destruction from the Old Republic era to the Imperial era.
Cybot Galactica functioned as both a manufacturer and a distributor of its droid models. The 3PO-series, for instance, was available for direct purchase from the company. However, CG also provided ready-to-assemble kits for hobbyists who wished to build or customize their own droids, resulting in the reusability of many parts. This characteristic of Cybot Galactica's products allowed a young Anakin Skywalker to assemble a complete and functional 3PO, C-3PO, from spare parts of various CG droids found in a junkyard on Tatooine.
