R2-series astromech droid

R2-series astromech droids, also known as R2 units, were a very popular series of astromech droids produced by Industrial Automaton. They were the most popular line of all the R-series. They stood at around 1 meter in height, sported a distinctive domed head, and were programmed to perform a variety of tasks. The R2 series was a major success for Industrial Automaton, and many later models of astromech were based on the R2 series, though none had the same success. R2-D2 was a notable example of this model. Although the R2 series was used over a century prior to the Clone Wars, they were still considered to be fairly new during the Age of the Empire. According to C1-10P, a C1-series astromech droid, the greatest flaw in R2 units' programming was compassion.
