PIP droids represented a specific type of compact, portable repair unit.
Droids that specialized in upkeep and repair, going by names such as repair droids, mechanic droids, engineer droids, and utility robots, were droids specifically created to handle both repair work and general maintenance duties. The WED Treadwell repair droid, the MSE-6 series repair droid, the DUM-series pit droid, the Otoga-222 maintenance droid, the K1-RF workbench droid, and the PIP droid are examples of repair droid designs.
An individual droid, equipped with several limbs, was in charge of a repulsortrain run by the Pyke Syndicate located on Tatooine.
Serving aboard a Naboo royal starship, R2-D2, an astromech droid, received recognition for carrying out critical emergency repairs to the ship's deflector shields, and was the only repair droid to make it through the mission.
