DLC-13 mining droid/Legends

The Mustafar Panning Droid was a droid that worked on Mustafar to mine gold from its lava rivers. The panning droid was presumbly well shielded to help it survive the extreme temperatures, as evidenced when one unit survived a dunking in a lava river when Anakin Skywalker landed on top of it when dueling Obi-wan Kenobi.

The panning droid possesed only a rudimentary droid brain: its orders were transmitted to it from the primary mining facility. When they didn't have a job to do, they tended to aimlessly hover around, as shown when a panning droid observed a standoff between Obi-wan and Anakin on lava river spanning conduits; the droid floated off after only a few seconds.
