A DRD is a fictional item in the 1999-2003 science fiction television series Farscape. DRD is short for diagnostic repair drone and they are small robotic tools that perform routine maintenance and repairs on Leviathan-class transport ships. When not needed, these drones remain inert in special housings behind the corridor walls of the ship. DRDs perform routine maintenance functions, effect minor repairs and basically execute any and all tasks that either Pilot or a crew member may be incapable of performing on their own. The actions of a DRD are usually governed by the ship's pilot, who maintains constant communication between the ship's living brain and it's mechanical control functions. DRDs also serve as support staff to a ship's crew, performing a variety of functions such as providing injections of translator microbes.
On Farscape, most of the DRDs seen in the series were constructed and stationed aboard the Leviathan ship known as Moya. One DRD of note was put to use on another such vessel called Elack. Astronaut John Crichton taught the robot to whistle the 1812 Overture. John dubbed the DRD 1812 and painted the number upon it's side.
