YI-5
this series of droids was produced for use in surveillance and forensic investigations, during the height of the New Order. Most of the YI-5 droids that were produced went to the Imperial Security Bureau. The YI-5 proved its worth almost immediately, when one of the first droids used by the ISB caught the actions of Vune Willic on a variety of media, which were later used in presenting evidence at Willic's courtmartial trial. The YI-5 was a small, insect-like droid that was shaped like a flattened oval. A miniature holocamera and two sensor eyes - one red, for heat signatures; and one blue, for light signatures - sat atop the body. Four sockets for mounting a set of manipulator arms were located on the belly, and a unique stealth field package gave the YI-5 a form of shielding that altered its coloration to match it surroundings. When Ysanne Isard first saw the YI-5 in action, she believed that the two sensor eyes were colored red and blue as a subtle jab at her own eye color. Only the effectiveness of the YI-5 in bringing Vune Willic to justice, along with the assurances of the Empire's own engineers, persuaded her to rescind the termination orders against the designers.
