About time I make an actual post about the search and rescue drones. I'm using Khan as an example because I haven't made a character of this type yet.
Search and rescue drones were a vital part of settling Bismuth-12. They were designed as a first line of protection. On other planets, they were guards for camps and rescued lost hikers. On Bismuth-12, they were protecting much more. When first settling the humans encountered highly dangerous and aggressive alien life forms. Territorial and protective of their wild planet. The rescue drones worked closely with the military drones during this time. After the fall, a good number of the rescue drones that couldn't make it to a colony were taken in by these military drone squads. Respecting the camaraderie they shared during those early years of settlement.
The rescue drones were broken up into squads. Wolf squad, Bear squad, Deer squad, so on and so forth. The groups were typically made up of five drones and five mountable sentinels fashioned after their squad name. Within each squad, there was an 'admin' drone and an 'admin' sentinel. (In this case, the admin drone in question was Khan.) The admin drones held the system that connected their squads. Allowing them to communicate and add to a communal map. Marking places of interest, danger, and safe passageways. These maps have become crucial in the time after the fall. Each squad had its own map with unique information, though squads would often come together and swap their knowledge.
It was thought that only squad members could access these maps. Later on, as drones began having children, it was found that the children of rescue drones could also access these maps. (For example, even though she is a standard worker. Uzi would have access to her father's map data.) Due to this, it is not uncommon that children of rescue drones go on to become squad leaders. Continuing to contribute to the maps and pathways. Even taking on the role of caring for the sentinel upon a parent's retirement from their work.
As you can imagine, the schematics for rescue drones are highly sought-after. They are also the hardest to find. Many of the places that they were kept have long since been destroyed and overgrown after the fall. This makes the schematics for rescue drones very rare and very high-value.
