R4-J9

R4-J9 was one of three droids assigned to a droid pool that included R4-S2, which managed to survive the Twileki scouts' ship crash and repair itself. The unit also went on to work for the administrative droid, QS-2D like R4-S2. Both astromech droids surveyed mineral deposits on the moon of Uffel and set up mining operations to obtain raw materials to manufacture droids.
