Holocam E-series cam droids represented a line of compact and affable holocam droids that possessed a female personality and appeared to have a foundational understanding of mechanics, technology, and science. These droids, manufactured by Trang Robotics, were designed to offer guidance and useful suggestions in a pleasant and timely manner.
Notably, a droid of this type, referred to as "Cammy," played a role in assisting a Rebel operative in locating and gaining access to a factory producing assassin droids located on Tatooine.
