Chiba DR - 10 protocol droid The Chiba DR - 10 protocol droid , sometimes known as the " Chiba Drio , " was a small , spherical protocol droid produced by Chiba Corporation , and preferred by diplomats of the Galactic Empire . Unlike most protocol droids , the Chiba DR - 10 floated on repulsorlifts and was equipped with a small , concealed blaster . The droid was originally designed to be used for negotiations and translation for legal purposes , but it also saw service in shops and customs checkpoints . However , the droid had a flaw where it became aggressive and irritable during negotiations it was losing , and sometimes the droid deployed its blaster without warning . The Empire exploited the flaw and used the droid for security and as a probe droid . During the Galactic Civil War , which was fought between the Empire and the Alliance to Restore the Republic , Moff Jander Graffe used two Chiba DR - 10 droids while on the planet Esseles . Description . The Chiba DR - 10 protocol droid was a small , spherical third - degree droid , which was equipped with repulsorlifts to hover over the ground . The droid was armed with a small , hidden blaster , an unusual feature for a protocol droid . The weapon could be deployed quickly from a hidden compartment on the droid ' s underside and had about the same range and power as a blaster pistol . Due to the droid ' s small size and repulsorlifts , it was quite agile , but it was unable to lift much weight . The droid had a small probe that it could use to manipulate objects . In order to communicate over long distances , the DR - 10 was equipped with an integrated comlink . Some variants of the droid had a recording unit along with extensive sensor equipment , which included 360 - degree , infrared , and telescopic vision as well as motion sensor s . Other models of the droid came equipped with translator unit s in order to interpret languages . Some of the droids had black - colored photoreceptors , along with plating that was white , black silver , and copper - colored . The droid had its photoreceptors on the sides of its spherical body , and it had a black - colored protrusion on its top side . Role . Chiba DR - 10 protocol droids were originally designed for the purposes of negotiation and translation , tasks aided by the vast amount of information contained in the droids ' memory banks about law , customs , trade , and business matters . The droid had enough knowledge of Imperial law that it could provide individuals with legal advice . Some of the droids had translator units to help in translation , and they were programmed to speak and understand Galactic Basic Standard , binary , as well as five languages that could be chosen by the owner . However , the Chiba DR - 10 had a programming flaw that caused it to become more and more sarcastic , irritated , impatient , and aggressive when it had difficulties with obtaining the desired outcome in a negotiation . The flaw was due to the fact that the droid had behavioral inhibitors that were programmed differently than those in other protocol droid models . Sometimes Chiba DR - 10s became frustrated enough to deploy their blaster and start shooting , which frequently occurred without warning to others present . The DR - 10 also used the blaster when negotiations failed violently . The droid ' s excellent perceptiveness also made it useful for security duty or as a probe droid . Its small size , repulsorlifts , and its nature to ask questions before firing also made it useful for security tasks . Despite the Chiba DR - 10s ' flaw , they were highly intelligent and could be very persuasive and diplomatic . However , the droids could also be quite deceptive . Some units from the line were also programmed to use computers and to appraise the value of items . Some Chiba DR - 10s were equipped with heuristic processor s , which were expensive processors that allowed the droids to think creatively , but others only had basic processor s , which did not allow for such versatility . History . The Chiba DR - 10 protocol droid , which was also known as the " Chiba Drio " , was produced by Chiba Corporation during the time of the Galactic Empire . Units of the model could sell for prices of 9 , 500 credits to 12 , 000 credits for those who were allowed to own such restricted droids . The DR - 10 was first used as a negotiator and translator droid for legal matters , but it was eventually used in not only law offices , but also in shops and custom checkpoints all throughout the galaxy . The droid was also used by the Galactic Empire in large numbers and was favored by Imperial functionaries and diplomats whose line of work took them into danger . Due to the droid ' s flawed programming , which was viewed as notorious by many , the forces of the Galactic Empire also used the droids as guards , probes , and for other security purposes . Jander Graffe , the Moff of the Darpa sector , had two DR - 10s in his service when he was ordered by the Empire ' s ruler , Emperor Palpatine , to fake alien riots on the planet Esseles in order to support raising security taxes there during the Galactic Civil War . At one point , Moff Graffe ' s Chiba DR - 10s were nearby when the Rebel spy Deena Mipps and a group of individuals filmed a conference between Graffe and other government officials , a meeting where they plotted to cause riots among the alien population of Esseles to obtain more taxes for security purposes . Although they came close to stopping the Rebel team , the Chiba DR - 10s and the Moff ' s other security forces were unable to do so . Behind the scenes . The Chiba DR - 10 protocol droid was first featured in " A Taxing Party " , an adventure seed that was contained in " Coruscant and the Core Worlds " , a " Star Wars Roleplaying Game " sourcebook published by Wizards of the Coast in 2003 . The book was written by Craig Robert Carey , Chris Doyle , Jason Fry , Paul Sudlow , John Terra , and Daniel Wallace for the revised edition of the " Roleplaying Game " . In addition to being part of the adventure , the droid received a descriptive section in the book ' s Esseles entry with an illustration by Tommy Lee Edwards . In 2009 , the Chiba DR - 10 received an entry in " Galaxy at War " , a book written by Rodney Thompson , Gary Astleford , Eric Cagle , and Daniel Wallace for the " Saga Edition " of Wizards ' " Star Wars Roleplaying Game " . For the " Saga Edition " of the " Roleplaying Game " , the Chiba DR - 10 was available for players to use for one of their characters . While " A Taxing Party " mentioned Emperor Palpatine and the Rebel Alliance , neither " Coruscant and the Core Worlds " or " Galaxy at War " specified the era when the droids were in use . Additionally , the " Galaxy at War " entry contained much information on the Chiba DR - 10 that differed from its first entry . The cost changed from 12 , 000 credits to 8 , 000 credits , while the processor changed from a heuristic processor to a basic processor . The droid ' s improved sensor equipment was also removed and replaced with a translator unit . This article treats the two different versions of the droid as two variants of the same type of droid .
