A typical servo-skull

A servo-skull is a robotic device common throughout the Imperium of Sidhae.

Servo-skulls fulfill a variety of roles commonly entrusted to autonomous flying drones elsewhere. Despite being very diverse in form and function, all servo-skulls share the same basic design of a body shaped like a human (or more rarely, an animal) skull, which houses the unit's CPU, power source and sensor package. A small grav repulsor is mounted underneath the skull for propulsion, various parts and tools to adapt the unit for it's intended function being attached externally. The aforementioned tools can incorporate anything from flashlights to firearms and shield projectors. Most models include at least two flexible graspers in their array of tools.

Servo-skulls serve in very diverse roles, essentially only limited by the amount of hardware their small repulsors can carry aloft and the imagination of their creators. Most are used in mundane roles, such as couriers, mobile illumination sources, repair assistants and sentries. More advanced variants are used by the military and other Imperial agencies as scouts and combat support platforms.

A servo-skull is typically fitted with a rudimentary AI designed for a particular function, which can sometimes be something as simple as hovering next to it's charge and providing illumination. More sophisticated models, however, incorporate advanced AIs that allow servo-skulls to coordinate and operate in groups, this feature being especially useful in industrial and military applications. Servo-skulls can be slaved to a particular individual with the right augmentations, serving as extensions to his senses and allowing one to direct them at will.

It is unknown why Sidhae have chosen to design these ubiquitous drones in the shape of skulls, especially in light of other, more practical drone designs coexisting with the servo-skulls. Given the general Sidh cultural obsession with Gothic aesthetics, it is probable that servo-skulls have gained their popularity solely for aesthetic reasons rather than any innate practical advantages.
