The OX9 labor droid was a model of labor droid employed by the Trade Federation. It was essentially humanoid in shape, short, stocky, with large plate-like hand appendages to facilitate carrying large loads. They were also capable of constructing various buildings. They had elongated heads, were the same beige color as B1 battle droids, and spoke in warbling droidspeak. OX9 droids were produced at command centers.
