Description
The WED Treadwell repair droid is a parent model of service droid that employs various sub-model for various usage. They were developed by Cybot Galactica and utilized in outdoor terrains on many Outer-Rim worlds such as Tatooine. These droids were used quite extensively during the years surrounding the Clone Wars. The droids had a small rolling tread chassis, which was ideal for movement across sandy terrain. They also possessed multiple articulating arms that could perform routine functions simultaneously. The central body was a cylindrical shaft to house the arms, which terminated in a sensor display for its head.

One series was the WED-15 Septoid Treadwell, which was used by Owen Lars to effect repairs on his moisture vaporators. A similar model, the WED 15 2 Septoid was also employed on Tatooine. One of these droids could be seen when the Jawas first came to the Lars homestead looking to sell their wares.

Another such droid was used by the Rebel Alliance on Hoth. It could be seen moving about the hangar bay near the Millennium Falcon at Echo Base.
