OLR - 4 OLR - 4 was an OOM command battle droid stationed aboard the Trade Federation " Lucrehulk " - class freighter " Revenue " . In 33 BBY , over the Outer Rim planet of Dorvalla , he was tasked with patrolling the hangar of the freighter for any suspicious activity . He encountered a cargo pod with unusual sounds emanating from it . After OLR - 4 observed the pod for a few moments , it disgorged mercenaries belonging to the Nebula Front criminal organization . In the following firefight , OLR - 4 was destroyed , along with other B1 battle droids that had been assisting him . With their path unhindered , the mercenaries were able to seize the valuable aurodium ore being carried by " Revenue " . Biography . Manufactured by Baktoid Combat Automata for the Trade Federation , OLR - 4 was a commander droid variant of Baktoid ' s B1 battle droid , the OOM command battle droid . In 33 BBY , he was stationed aboard the " Lucrehulk " - class cargo freighter " Revenue " on security detail . In that year , the freighter was in the orbit of the Outer Rim planet Dorvalla , loading lommite ore that had been mined on the planet ' s surface . Once carried to " Revenue " , the ore was loaded into the ship ' s vast hangars by repulsorlift - powered cargo pod s before being distributed between three zones in the each of the two hangars . It was in the second of these zones in the starboard hangar that OLR - 4 was tasked by " Revenue " central control computer to flag any event that was placed outside parameters set by the control computer . These parameters were triggered when the sound of pressure relief valves was heard from a cargo pod that was slowly opening its over - sized access hatch . Once the central computer had verified the anomaly through data from OLR - 4 ' s photoreceptors , additional B1 security droids converged on the pod and took combat stances . Five droids were destroyed by the forceful opening of the pod and two more were destroyed by blasterfire from inside the pod . The remaining droids , including OLR - 4 , returned fire on the intruders , mercenaries belonging to the criminal organization Nebula Front with intentions to steal the aurodium ore aboard " Revenue " . With three more of the droids falling , OLR - 4 moved around the pod to get an advantage on the mercenaries but found that his blaster was overheating and near depletion . Despite this , the central computer still commanded that OLR - 4 keep firing . Attempting to run toward the cargo pod , OLR - 4 was shot in both shoulders and knocked to the floor . With the intruders believing all of the droids to be disabled , he was able to furtively glimpse the bipedal humanoids that had boarded the freighter . He then attempted to fire his blaster at one the mercenaries standing above him , a Human , but the overheated blaster shut down and OLR - 4 unintentionally gave himself away by exclaiming at the useless weapon . Alerted to his presence , the Human spun around and shot the droid . As OLR - 4 ' s systems failed , he managed to relay his final view to the central computer to alert the crew before he finally shut down . However , despite the alert by the central computer , the crew of " Revenue " were unable to stop the Nebula Front from seizing the precious aurodium . Characteristics . OLR - 4 was a standard OOM - command battle droid and so was equipped with a little more artificial intelligence than the regular B1 - battle droid . Similarly , his chassis was painted with yellow markings that signified his commander status . Before taking action on the anomalous sounds from the Nebula Front ' s cargo pod , OLR - 4 had to wait for " Revenue " central computer to determine the nature of the anomaly for him . This proved to be a disdvantage to the droid when the mercenaries emerged from the pod before the computer could relay a suitable action to take . When he had been knocked down in the firefight , OLR - 4 still attempted to attack the intruders with his depleted BlasTech - manufactured weapon , an action that led to his destruction . Behind the scenes . OLR - 4 appeared as a minor character in the first chapter of James Luceno ' s 2001 novel , " Cloak of Deception " . His only speech in the pages he appeared in was an exclamation shortly before his destruction .
