Specially designed for deep space exploration, and reconnaissance, probe droids are employed in science and military applications. They gather data and transmit it to their masters over vast distances. Tenacious hunters and searchers, probe droids (or
probots) have a variety of sensors, and the ones employed by
the Empire are armed with powerful
blasters and, in some models, shields.
Most probots are launched in one-way pods which transport the droids to their target locations. Once there, they gather information. If confronted with a hazard, the droids can protect themselves. If confronted after their main mission has been completed these droids can selfdestruct.
Imperial probes are vaguely arachnid in shape, with a dark metal finish, bulbous sensor "eyes" and spindly manipulator arms. They hover along on repulsorlift engines, with their arms touching the ground to gather samples. After the Battle of Yavin, the Empire dispatched thousands of probe droids to hunt down the Rebel base. One of these droids eventually revealed the hidden base on the ice planet Hoth.
