DSD1 dwarf spider droid / Legends The DSD1 dwarf spider droid , also known as the burrowing spider droid because it was first used to destroy opposition in narrow mine shafts , was a battle droid manufactured by the Commerce Guild to support the cause of the Separatists . Characteristics . The DSD1 was similar in function to a typical combat vehicle . It was also used to punish customers who had declined to pay their taxes to the Commerce Guild . Its main weapon was a long central blaster cannon mounted on its dome that was capable of firing either rapid anti - personnel rounds , or slower high - intensity blasts that could destroy light vehicles . The droid ' s small frame and four all - terrain legs made it suitable for warfare in dangerous mines , and the adjustable legs let it attain better elevation for the blaster cannon . Its legs were able to walk straight up and down walls and narrow cliffsides . However , because of the fixed laser cannon , it could not turn around to track enemies , thus making it inferior to speedy targets . Also , the length of this cannon sometimes hindered it in confined areas , a weakness that Anakin Skywalker exploited on Escarte . The droid communicated in a beeping language similar to Binary . It seemed to have basic emotions , such as frustration , as demonstrated on Escarte and Teth . They didn ' t do anything they predicted would harm them . History . During the Clone Wars , dwarf spider droids were used on the front lines , in front of platoons of battle droids and other Separatist droids . They were notably used during the Battle of Teth , using their laser cannons to hit the feet of the AT - TE walkers , causing the walkers to fall down the cliff . During the Second Battle of Felucia , there was a large group of them inside the Separatist base , presumably as a nasty surprise to the Republic troops that got in . The dwarf spider droid also worked in conjunction with the larger OG - 9 homing spider droid and could operate as an armored scout exploring the battlefields . Infrared photoreceptors and powerful scanners enabled the droid to survey the terrain and relay target data back to the Homing spider droid . When it identified a target , it sent a tracking message through a digital channel from its head - mounted aerial to the homing spider droid , which then moved toward the signal to deliver the killing blow . It also featured a self - destruct mechanism . If a clone unit moved in to destroy the droid , it would usually self - destruct , destroying any enemy / enemies around it . Several variants of the dwarf spider droid saw action during the wars , including an amphibious model , designed for water - filled terrain such as marshes , swamps or wetlands , equipped with a larger gun , but could not float , as well as two heavily armored variants — the heavy dwarf spider droid and the advanced dwarf spider droid . Delta Squad encountered many advanced dwarf spider droids on their missions including 2 during the Battle of Geonosis , and several during the Battle of Kashyyyk , where they were used to counter the Republic ' s All Terrain Recon Transport units . Though most Separatist war vehicles were deactivated after the end of the Clone Wars , the dwarf spider droids were recommissioned through Imperial command and used by the Galactic Empire to enforce the submission of former Separatist worlds , fighting against the remnants of the very government that once used them , with the Stormtrooper Corps using the droids as their mechanical attack dogs . They would remain utilized throughout the Empire ' s reign , and it was not uncommon to see these droids alongside stormtroopers at Imperial checkpoints . Behind the scenes . The dwarf spider droid first appeared in . Early in production , the plan was for the various commerce guilds to employ the same type of battle droids used by the Trade Federation , only with different color schemes to differentiate allegiance . It was instead decided to provide a greater visual diversity by designing wholly unique droids for the Commerce Guild , Corporate Alliance , and InterGalactic Banking Clan .
