Holocam E-series cam droids were a series of small, friendly holocam droids, programmed with a female personality and seemingly at least basic level mechanical, technical, and scientific knowledge. Produced by Trang Robotics, Holocam E droids cheerfully dispensed advice and helpful hints as they became relevant. One of these droids, known as "Cammy", helped a Rebel agent to find and infiltrate an Assassin Droid factory on Tatooine.
