The R5 line of astromech droids, also referred to as the R5 series astromech droid, represented a specific model produced by Industrial Automaton within the R-series of droids.
These droids, standing at a height of 0.97 meters, were generally built with shorter, cone-shaped heads and included repair arms. As budget-friendly alternatives to the more advanced R2 units, they were inexpensive. However, they were notorious for their frequent breakdowns, flaws, and unpleasant personalities. Industrial Automaton was forced to discontinue the model to protect its image due to its poor standing. Notable R5 units include LX-R5, who assisted Jedi Master Kelleran Beq, and R5-D4, one of the final droids made in the R5 series. Furthermore, R5-D8, R5-K6, and S4 were R5 droids that aided the Rebel Alliance throughout the Galactic Civil War.
