Droid armor was the designation for protective plating applied to droids to shield them from environmental factors like temperature extremes and physical damage. The composition of these protective layers varied widely, incorporating materials like metal alloys, durasteel, or bronzium, with the quality and cost determined by the droid owner's investment. A range of armor types existed, including Impact armor, engineered to mitigate the effects of daily wear and tear in demanding environments, and Modular plating, conceived as a lighter, yet robust, alternative to bulkier, more restrictive armor options.
