Science Research Droid The Science Research Droid — designated the S2R droid by the Imperial Military — was a biological science droid constructed by TelBrinTel Corporation for use in the Galactic Empire ' s chemical and biological weapon projects , as well as armor and power - guidance system development . It was a vaguely humanoid unit measuring 1 . 9 meters in height , with two fine - control manipulator arms and two legs possessing a suspension system that cushioned its steps . It was built with an advanced protocol chip for communicating with organic scientists , a molecular microscope and sophisticated olfactory analysis technology , and an " endosystem " designed to mount accessories on six ports located in its upper torso . The droid ' s success in the Imperial Military led TelBrinTel to create the civilian S2R ( A ) model , designed to match the original droid ' s performance but with security features preventing it from working on weapons or military projects . Description . The Science Research Droid was a first - degree droid of the biological science class measuring 1 . 9 meters tall and having a vaguely humanoid appearance . It possessed a highly advanced protocol chip in its droid brain , enabling it to engage in " creative brainstorming " sessions with living coworkers . Its monocular eyepiece contained a high - powered , multi - spectrum molecular microscope , and it possessed olfactory sensors and a sophisticated olfactory databank and analysis package . Its two arms were designed for fine control and manipulation , and its two legs were equipped with a suspension system that cushioned each step , preventing unstable chemicals and compounds from potentially dangerous jarring . The droid ' s upper torso held its " endosystem , " a marketable feature that provided six ports on the droid ' s vertebrae for the attachment of dockable accessories . These accessories could include additional arms , work surfaces , or small tools or injection needles . History . The Galactic Empire commissioned the Science Research Droid from TelBrinTel Corporation for use in the Imperial Military ' s chemical and biological weapon programs , and also for research into new armor and power - guidance systems for the Imperial Navy . The droid , designated the " S2R droid " by the military , first reached Imperial research centers in large numbers immediately after the Battle of Hoth in 3 ABY . A large portion of this initial shipment wound up in the hands of the Alliance to Restore the Republic . Despite this , the droid ' s performance in the Imperial Military was regarded as a marked success , leading to production of a civilian - oriented model . This model , the S2R ( A ) , performed many of the same functions as the initial model , though hardwired protocols prevented the droids from knowingly working on weaponry or projects with military applications . These protocols could be bypassed , but secret programming installed by TelBrinTel would then kick in , causing the modified droid to modify chemical formulas so that the resultant products were inert . The original Science Research Droid caught the attention of Toria Tell , a droid inventor and collector who maintained " Toria Tell ' s Droid Journal , " a small , private scandoc distributed in a limited fashion around the galaxy . The droid was also featured in Version 4 . 7 . 110 of Cynabar ' s Droid Datalog , which discussed both the S2R and S2R ( A ) models . There , Tell added commentary to the droid ' s entry , informing readers of the surreptitious programming added by TelBrinTel to thwart those who bypass the hardwired protocols of the S2R ( A ) . Another reader , a slicer using the pseudonym " Ranger , " confirmed Tell ' s information . Ranger had been hired by Rebels to remove such safeguards in similar droids , and noted that the TelBrinTel subroutines were quite subtle , hard to locate , and deeply ingrained in the droid ' s systems . Numerous TelBrinTel science droids were used by the Baobab Archives , which assigned many of them to analyze the " Dha Werda Verda " , an ancient poem etched into Roonstone s discovered by the merchant Mungo Baobab . One notable Science Research Droid was Geth . This droid had been modified by former Rebel General Reesen Jivrak , who had been ejected from the Rebel Alliance for his unethical and cruel conduct . He used Geth to create toxins that would strengthen and enrage the docile deripor s of Ohratuu for use as mounts in hit - and - run attacks . Behind the scenes . The Science Research Droid was introduced in " Toria Tell ' s Droid Journal " , an article written and illustrated by Christian Piccolo , published in " Star Wars Adventure Journal 10 " in May 1996 . The droid was subsequently included in " Cynabar ' s Droid Datalog , " an article written by Drew Campbell and Eric S . Trautmann for " Star Wars Adventure Journal 13 " , released in May 1997 . TelBrinTel science droids later appeared in " " , a book written by Daniel Wallace and Josh Ling and published by Chronicle Books as part of the Star Wars Masterpiece Edition in September 1999 , though whether these droids were S2R or S2R ( A ) models was not specified .
