R2-V Navigator Droid

The R2-V series of Navigator droids was created by Industrial Automaton.

Appearance
R2-V units had a small, stocky chassis, and they were similar to the R2-B Minimech Droid.

History
R2-V units were created by Industrial Automaton to act as navigators for Starship Pilots. These small droids could hold up to 10 hyperspece jumps in their memory, and they were equipped with a hypertransciever so that their owners would communicate with one another through Hyperspace. R2-V units were often used by the Old Republic on board of large warships.

Trivia

 * The R2-V series Navigator Droid is based on an unnamed Astromech droid in Star Wars: Droids.
