The ID9 is a model of seeker droid initially designed and produced by Arakyd Industries to serve as a repulsor-equipped security unit with built-in armament and communications gear that could fit in a tiny compartment for easy transport. The droid’s main body resembles a pair of small saucers joined along the rim, with a cylindrical photoreceptor in the front. A short, straight antenna juts from the dorsal surface and a cluster of five double-jointed arms hangs from the ventral surface, each one ending in a pincer-shaped appendage. The droid can either scuttle along on these appendages or use its built-in repulsorlift generator to hover and propel itself around.

The ID9’s body is no more than fifteen centimetres in diameter, and the same in height, measured from the top of the antenna to the sockets where the arms join the body. The arms are approximately forty centimetres long when hanging straight down. The original batches of ID9 droids were painted matte black overall, with only the red lens of the photoreceptor providing a splash of colour. The cylindrical photoreceptor module also houses a miniature blaster, enabling the droid to defend itself or even to be used in an assassin role if required. The droid can also vocalise sounds made by other robots, a useful function that can be used to distract or confuse people who are searching for it. While the original production run has stopped, a number of these droids are still being produced in small droid shops for sale to security forces as well as to less savoury organisations.
