"I live to serve."

The MD-4 was a model of medical droid and a part of the MD-series that was manufactured by Industrial Automaton. It was slightly humanoid in appearance.

This droid model had specialized appendages for performing microsurgical procedures and could perform these without assistance.

The MD-4's microsurgery appendage

Industrial Automaton's MD-4[1] first-degree droid[3] was part of the MD-series of medical droids.[1] Related to the 2-1B surgical droid—another of Industrial Automaton's products[2]—in terms of aesthetic design, it was 1.5 Imperial standard meters tall[4] and had a torso unit with two arms topped by a cranial unit.[4] The legs[3] were shrouded in a surgical gown to protect delicate internal mechanisms.[2] MD-4 droids were ambidextrous.[3]

MD-series droids generally had gray plating and green highlights. The photoreceptors were yellow.[4] Costing 2,000 credits, MD-4s were available for purchase throughout the galaxy.[3] The torso was the location of a connection socket to allow the droid to directly connect to a computer.[2] The MD-4 employed reduction servomotors and actuators to give their arms slow, precise movements to perform complex surgical procedures.[1]


MD-4 droids were intended for surgical purposes, with specialized microsurgical appendages, including miniaturized vibroscapels, flex clamps, and fiber optics.[1]


Constructed on the droid factory world of Telti,[2] they were employed by the Empire during the Galactic Civil War. Aboard the Imperial EF76 Nebulon-B escort frigate Far Orbit, an MD-4 droid oversaw the surgical unit.[5] Three MD-4 droids served under Doctor Momaw Mowadan aboard the luxury liner Kuari Princess.[6] Antar Roat, Wedge Antilles' cover identity to infiltrate Coruscant in 6 ABY, was said to have been treated for battle injuries by MD-4s.[7]
