Astromech droid

Astromech droids, also referred to as astro droids or mechs, were a type of repair droid that served as an automated mechanic on starships. These compact droids used tool-tipped appendages stored in recessed compartments. Many starfighters relied on astromech copilots to control flight and power distribution systems.Star Wars: The Force Awakens: The Visual Dictionary Sitting in an astromech socket exposed to space, the droid, in addition to its piloting duties, could calculate hyperspace jumps and perform simple repairs. The astromedic was a mix between an astromech and a medical droid.Star Wars: Commander
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, known as binary. However, certain other droids, such as the protocol droid C-3PO, could understand the binary code of astromechs, and often translated from binary to other languages.

R-series droids had three wheeled legs. The later BB-series astromech droids were spherical, giving them the ability to roll. Some astromechs, such as OC-JK14, were moved on treadwells.
