SE-2 worker droid

The SE-2 worker droid, also known as the farm droid, was a loose-jointed model of utilitarian menial labor droid featuring a monocular photoreceptor with dual-imaging plane. An SE-2 named "Essie" worked on the farm of Galen Erso, and alerted the Erso family when he spotted Director Orson Krennic's Imperial shuttle approaching the homestead and alerted the Erso family in 13 BBY.
