The Hound-W2 SPD represented a type of security droid manufactured by Industrial Automaton. These droids possessed a rectangular form factor and stood approximately half as tall as an astromech droid.
Their locomotion was achieved through wheels, and they featured four extensible arms capable of spanning a distance of 15 meters. The extremities of these arms were equipped with diverse sensors, including a laser scan emitter, a pulse scan emitter, and a thermal imager. Lacking a vocabulator, their communication was limited to Droidspeak, a feature regarded as their sole drawback. They ranked among the top-tier security droids available.
Hound-W2 units saw common deployment at security checkpoints, where they were assigned the role of identifying illicit substances, such as spice or explosives. They were deployed to patrol the Grand Corridor in search of Delta Source.
