A droid used by CorSec to combat Jedi was the sonic generator droid. These droids were utilized as part of the defensive measures against a potential Galactic Alliance assault on Centerpoint Station. While similar in appearance to astromech droids, these droids replaced the typical head with a sonic generator. Their sonic attacks were capable of incapacitating Jedi without killing them. To avoid unintended harm, Corellians in the vicinity employed sound-canceling devices.
