Translator droids, also known as interpreter droids, were droids skilled in translating one language into another. Their function was usually performed by protocol droids. The RST Model Translator Droid and M-TD miniaturized translator droid were two types. Interpreter droids carried out errands within the New Republic Senate's Grand Convocation Chamber. A translator droid was used aboard the Chimaera in 8 ABY to translate the Gand that C-3PO was using in order to convince the crew that the Regina Galas was just an ordinary vessel captained by a Gand.
