- "Madam, I am a protocol droid. Civilized is what I do."
A protocol droid was a droid whose job was to aid sentients with their etiquette and relations with each other in the galaxy. They often dealt with event planning, etiquette, translation, and problem solving. Typically 1.67 meters tall and 75 kg in weight, protocol droids came in many shapes and sizes, although most were humanoid in form. They were equipped with a AA-1 VerboBrain. Models included Cybot Galactica's 3PO-series protocol droid, Arakyd Industries' RA-7 model, and Lothal Logistics Limited RQ protocol droid. Cybot Galactica manufactured its protocol droids on the factory world of Affa. They were also available as kits to hobbyists.
