T3-M4 is one of the most common repair droids of the Old Republic and the ancestor of the famous R2-D2. Approximately one meter in size, T3 and other models of the "T" project can move quickly and use weapons such as an electro-shock device against droids or a built-in blaster. T3 models also have devices for repairing various devices. All "T" models communicate using droid language codes, and language drivers cannot be installed in them for normal communication with humans.
