The DDP-13 Personal Seeker Droid is a model of probe droid consisting of a half-hemisphere dome that houses its advanced sensor array, with long-range antennas protruding from the top and a red photoreceptor just below the dome. It is equipped with five tentacle-like limbs with pincer hands and electro-shock prods. Additionally, it is capable of both hovering and crawling, as well as imitating the sounds of other droid models. It is awarded to those who help defend the Dark Councilor Dracaryis.
T1-N1 is subjected to frequent memory wipes, and has little to nothing in the way of personality. It acts according to its basic programming in an efficient and impersonal manner.
T1-N1 has had its sensor suites upgraded to significantly increase their range and sensitivity, allowing this DDP-13 Personal Seeker Droid to collect and record a wide range of data during scouting operations. These sensors are far more sensitive to jamming interferance and are more prone to damage.
