The DLC-13 mining droid, which is also referred to as the Mustafar panning droid, droid lava collector, or DLC-13 panning droid, was a type of droid used in mining operations to retrieve precious ores from harsh locations, such as Mustafar and the Belgaroth asteroid field. These droids were constructed using heat-resistant carbonite.
After the Clone Wars ended, a number of DLC-13 droids were put to work on Mustafar. During the duel that took place between Obi-Wan Kenobi and Darth Vader, Vader jumped onto one of these droids and seized control of its steering mechanisms, resulting in the droid releasing its collection bucket into the lava below.
The DLC-13 mining droid made its initial appearance in the 2005 movie Revenge of the Sith, the third installment of the Prequel trilogy. The droid's history was further detailed in Legends materials, including works like The New Essential Guide to Droids and Star Wars: Complete Locations. Additionally, a mining droid with the name DLC-13 made a short appearance in the non-Canon LEGO Star Wars: The Freemaker Adventures episode titled "The Mines of Graballa," which originally aired on June 21, 2016.
