The AZ-series surgical assistant droid represents a medical droid model produced by Cybot Galactica and saw action throughout the Clone Wars. A notable droid of this type, named AZI-3, was in service to the Kaminoans within Tipoca City on the planet of Kamino, where it provided care for clones.
Instead of legs, AZ-series droids used a set of repulsorlifts to achieve hovering at low heights. The front of the head featured a pair of circular photoreceptors. While its primary arms had three digits each, the medical droid could store small items and produce a variety of appendages to personally perform complicated procedures, thanks to a compartment on its back. These appendages were equipped with tools such as fusioncutters, flashlights, scomp links, and anesthesia-inducers. The AZ-series droids were designed with several survival modes to handle emergency situations. One such mode enabled the droid to convert into a rideable repulsorcraft capable of carrying one passenger.
The primary programming directive for AZ-series droids, as surgical assistants, was to guarantee the well-being of their patient above all else; this included ignoring orders from commanding officers.
