Astromech droid

At the Resistance base located on D'Qar, we see a collection of R-series astromech droids together with a BB-series astromech droid. Mechs, more formally known as astromech droids or astro droids, functioned as automated mechanics aboard starships, essentially serving as a form of repair droid. These small droids were equipped with tool-tipped appendages that could be extended from internal compartments. A large number of starfighters depended on astromech copilots to manage the distribution of power, as well as to pilot the craft. When placed in an astromech socket that was open to space, the droid was capable of calculating hyperspace jumps and executing basic repairs, on top of its piloting responsibilities. The astromedic droid was a hybrid, combining the features of an astromech and a medical droid.

The exposed head of an astromech The primary method of communication for most astromechs was through a unique series of clicks, bleeps, and similar noises, which is referred to as binary; they could also communicate in writing, displayed via another computer system. However, certain droids, like the protocol droid named C-3PO, possessed the ability to comprehend astromech binary and frequently provided translations from binary into other languages.

The typical height for astromech droids was about 0.93 meters; however, R-series droids from the R2 line and later models measured slightly over a meter in height. In contrast, the astromech known as P2 was roughly the same height as a human.

Droids in the R-series were equipped with three legs that had wheels. The later BB-series astromech droids had a spherical design, which allowed them to roll. Some astromechs, like OC-JK14, used treadwells for movement. While this design was once common in the Outer Rim Territories, it had become less popular by 35 ABY.
