An R5-series astromech droid played a role with Wedge Antilles in the Battle of Geonosis during the time of the Galactic Civil War.
The droid was given to Antilles for this particular mission and flew alongside him in his X-wing. When Antilles' X-wing sustained damage to its right stabilizer, a consequence of being close to the destruction of Sarkli's Imperial escort carrier, R5 tried to repair the stabilizer. Unfortunately, the repair was unsuccessful, forcing Antilles to make an emergency landing on Geonosis. Following the crash, R5 ventured ahead of Antilles, successfully navigating past numerous battle droids and stormtroopers from the Clone Wars era. Eventually, it discovered a Jedi Starfighter, which it then powered back up. R5 then integrated itself into the Jedi Starfighter, acting as its astromech droid controller, which allowed Antilles to make his escape from Geonosis. Further, it armed the Jedi Starfighter with seismic charges, increasing the rebels' chances against the remaining escort carriers and TIE squadrons, and also brought a non-functional hyperspace ring back online.
