Description: WED-15-77, or simply Treadwell, was a WED-15 Treadwell repair droid that was built prior to the Clone Wars, serving moisture farmer Owen Lars on the planet Tatooine for more than twenty years. Treadwell often worked with Lars's nephew, Luke Skywalker, on the moisture vaporators of the family's farm. While working on a vaporator with Skywalker one day in 0 BBY, the droid suffered a meltdown, and Skywalker, eager to meet his friend Fixer at Tosche Station near the settlement of Anchorhead, abandoned the droid in the desert. Treadwell was subsequently taken by the scavengers of the desert.
WED-15-77, also known as Treadwell, was a WED-15 Treadwell repair droid that was produced by Cybot Galactica, one of the two largest droid manufacturing companies in the galaxy. Prior to the Clone Wars, which broke out in 22 BBY, the droid began to serve moisture farmer Owen Lars's family on the planet Tatooine. Treadwell worked with the protocol droid C-3PO at the Lars homestead until the Jedi Anakin Skywalker, who had built C-3PO as a child, visited the Lars family and took the protocol droid away.
Treadwell continued to serve the Lars family for more than twenty years, into the time of the Galactic Civil War. Treadwell liked to work with Beru Lars, Owen's wife, who gave the droid the same simple and predictable jobs. The droid often helped Lars's nephew, Luke Skywalker, in a variety of chores, such as repairing moisture vaporators out in the desert. Early in the civil war, not much before Biggs Darklighter, a Tatooinian farmboy was about to leave for the Imperial Academy, Treadwell broke down. Skywalker took parts of the droid to Laze "Fixer" Loneozner, one of his childhood friends, who worked as a mechanic near the settlement of Anchorhead. However, Fixer had a week's backlog, and he couldn't begin working on the droid. Finally, the Treadwell got repaired and returned to work. One day in 0 BBY, Lars asked Skywalker to service the vaporator units on the farm's south ridge with the help of Treadwell.
During the work, Treadwell used an uninsulated manipulator and consequently received an electric shock. Not much later, Skywalker spotted a space battle above the planet. He ran to his landspeeder and called for the droid to follow him, but Treadwell's engine exploded, and the droid suffered a final meltdown. For a moment Skywalker hesitated about leaving the droid behind, but since the vital components of Treadwell were shot, he left the smoking droid in the desert and decided to pick him up on the way home. He raced off to Tosche Station near Anchorhead to tell Fixer about the battle. Treadwell, meanwhile, was taken by the scavengers of the desert and, as a result, was not there when Skywalker went to retrieve it.
WED-15-77 was a typical class-five Treadwell repair droid with two rows of five treaded wheels on its base. The droid had a very small independent thought processor but had enhanced binocular fine-focus vision, which helped it to spot circuitry damage. The droid's enhanced photoreceptors were mounted on a long, telescopic stalk, which also held six arms, including an equipment test arm and various manipulators, at least one of which was insulated. By 0 BBY, Treadwell's movements had become unsteady, and only three of its arms were functioning.
Treadwell was capable of accomplishing even very specific tasks with close supervision, but it could not conduct complicated work on its own due to its limited intelligence. It was a recalcitrant yet hardworking droid that preferred helping Beru Lars, since she gave the droid simple and predictable jobs.
