The dwarf spider droid, officially designated as the DSD1 dwarf spider droid, represented a model of battle droid produced by Baktoid Armor Workshop. The Commerce Guild particularly favored this droid, initially deploying it against rebellious miners in subterranean conflicts. Due to its aptitude for navigating confined spaces, it also gained the moniker burrowing spider droid. Its armament consisted of a potent laser cannon nose-mounted, capable of both rapid-fire and concentrated, high-energy blasts. Furthermore, it demonstrated anti-aircraft capabilities, notably during the Battle of Teth and when it downed the gunship carrying the Bad Batch, Cody, Rex, Jesse, and Kix on Anaxes. The droid's four legs were specifically engineered to facilitate adherence and movement on vertical surfaces, such as cliffs, as evidenced during the Battle of Teth, where dwarf spider droids attached themselves to the cliff face of the B'omarr Order Monastery to gain a strategically advantageous firing position against approaching clone troopers and AT-TEs.
Subsequently, the dwarf spider droid became a common element within the droid army of the Confederacy of Independent Systems in their conflict against the Galactic Republic during the Clone Wars. Its underside was susceptible to explosive damage, a weakness exploited when Clone Captain Rex eliminated a dwarf spider droid by affixing a thermal detonator to its undercarriage during the Battle of Teth. Many of these droids were equipped with a self-destruction mechanism that would trigger upon facing overwhelming threats on the battlefield. These droids participated in combat from the war's early stages, including the Battle of Devaron, through to some of the war's concluding engagements, such as the Battle of Anaxes and the Battle of Kashyyyk.
