Astromech droid

"You stupid little astro droid!"

- A super battle droid to R2-D2, moments before being incinerated

An astromech droid, also referred to as an astro droid, was a type of droid that served as an automated mechanic on starships. Typically 0.93 meters tall, the compact droids used tool-tipped appendages stored in recessed compartments. Many starfighters relied on astromech copilots.

Most astromechs were only able to communicate in writing, conveyed via another computer system, or through a special code of clicks, bleeps, and similar sounds.
