MSE-6-series Repair Droid
The MSE-6-series repair droid, sometimes referred to as the mouse droid, was a small, box-shaped, wheeled general purpose MSE-series droid often used for delivery and maintenance purposes. MSE-6 units were ubiquitous on Star Destroyers and in Imperial installations during the time of the Galactic Empire. Commonly, mouse droids carried out cleanup and basic repair duties, and could serve in security and communications fields. Following the fall of the Empire and the decommissioning of the Imperial fleet, billions of MSE-6 droids have become available on the civilian market.
The MSE-6 stood about 25 centimeters tall and ran on four wheels. Although programmed with multiple capabilities, the droid was designed with only a singular function. A modular circuit matrix was installed beneath the droid's boxy shell, and contained programming for one skill.Since each droid possessed only a single skill, multiple mouse droids could chain together to pool their resources for more complex assignments. Trains of MSE-6 droids could often be seen guiding troops through military installations; this kind of duty required mouse droids to be programmed with complete readouts of their assigned areas. In addition, due to their use in military outposts, MSE-6 units were rigged to melt down if captured, giving the droids a strong self-preservation instinct.
