Lego Star Wars DSD1 Dwarf Spider Droid

Based on wookieepedia 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.

The design of this model is similar to the official Lego set, but I changed most of the parts of the droid to make it look like the real one.
