Appearance: The Droidette is an ultra-light ultra-minimalist automaton. They look like little more than constructions of tinker-toys, exposed wires and armatures, and bare batteries and simplistic cortices.
Usage: Droidettes are designed for minimal function and minimal cost. The machines are engineered to be button pushers, observers, and light duty menial laborers, handling simple tasks such as housekeeping in a factory or other large space (sweeping, cleaning up spills, handling basic tasks like painting or minor repairs, restocking bathrooms, inventory purposes, or controlling flow through an area.
Combat: Though poorly equipped for fighting, it is relatively easy for a droidette to carry a basic weapon, shoot it, and reload it. They have no tactical or strategic skill, and limited ability to avoid damage on their own, but they are very cheap. No military or security corp uses droidettes for this purpose, as they have access to skeletrons and other superior combat machines. Fighting droidettes is a sign of desperation or local militias.
