The WED Treadwell was a series of repair droids produced by Cybot Galactica, and found across the multiverse. The WED Treadwell was a four-armed (with additional sockets available) automaton propelled by a treaded base. The droid's photoreceptors were mounted on a long, thin telescopic stalk, from which protruded various tool-tipped appendages. The standard WED droid had sockets to support up to six manipulators, though variants carried eight or more. These limbs were easy to install and replace, and Cybot Galactica actively encouraged consumers to purchase a variety of appendages for their Treadwells.
