3PO-series Protocol Droid
The 3PO-series protocol droid was a Human-cyborg relations protocol droid produced by Cybot Galactica. The model series had very similar aesthetic design in its casing to other Cybot Galactica droid model series such as the TC-series, 3PX-series, and 5YQ-series protocol droids. 3PO-series protocol units were considered the most advanced Human-cyborg relations droids in the market for over a hundred years up to the end of the Galactic Empire.
Each droid was equipped with a SyntheTech AA-1 VerboBrain making them capable of storing enormous amounts of information, the additional memory space was often used to keep communication modules in the active memory so that long delays could be avoided while searching for linguistic information on mid-translation. A TranLang III communications module allowed them to be fluent in over six million forms of communication, even if they could not respond in all of them for a lack of proper communication appendages. They also had the skills necessary to quickly analyze new unregistered languages and translate them into more well-known ones.
They were even provided with an olfactory sensor that allowed them to comprehend pheromonal communication. Other useful features were a factory-standard restraining bolt mount, and the fact that their shutdown switch was conveniently located at the back of their neck, on a very easy to reach place
