The R5-series astromech droid was a line of low cost astromech droids built by Industrial Automaton. Based upon the success of prior astromech models, such as the wildly popular R2-series, Industrial Automaton intended the R5-series to cater to budget buyers at the cost of some functionality.

Because of their inexpensive construction, however, droids of this series were plagued by a number of design flaws—most obviously, a sullen demeanor and sharp attitude resulting from deficiencies in the machine’s personality matrix.


R5-D8 was an attempt to prove that the R5 series could be useful, especially after a few upgrades. D8 was fitted with multiple upgrades, mostly to try and fix the personality defects in the R5. The most notable upgrade was an Astromech Translator, so that the droid could communicate in more than just beeps and whirs. However the experiment was decided too costly, and D8 was left without his upgrades complete. After being stripped and salvaged, all that is left of D8 is the core R5 features, and a faulty Translator that allows the droid to speak using specific lines from old holodramas.
