I just wing it. Assume a mobile comm equivalent for a brain and communication, maybe use something like PRIS goggles to represent sensors, look at other things for thoughts on power, drives, etc.The controller might be the equivalent of a laptop. If the drone that size is meant for civilian use in a standard atmosphere it’s likely to be lightly constructed (1 Hull, no armor); drones built for use in vacuum or hostile environments will be more robust (and thus more expensive). Military drones that size probably aren’t mush more robust but would come with encrypted communications, maybe stealth or other more advanced capabilities. It would be tough to fit a functional weapon system on a drone that small, but maybe a snub pistol or needle pistol equivalent? Or a scaled-down laser pistol? For military use a laser target designator may make more sense.
