I’m still not actually certain this is still INT’s T3 robotic line, it’s very different from the rest of the line and arguably isn’t an actual weapon. It’s possible that the robotics perk get dramatically overhauled so it can apply useful bonuses to the drone but given that the drone’s base function is as a flying storage chest, the perk would have to have a wide array of bonuses to be able to be useful for both automated turrets and the Heli-PackRemember that the drone seems to be the tier3 robotic thingy, as such it will be available when you already have lots of perk points and lots of pockets in your clothing (except if TFP removes those pocket mods). I play vanilla without enlarged storage mods and at that time in the game I usually have neither encumbrance problems nor storage problems because of a motorbike with (what I feel is) generous storage and a tendency to scrap 80% of what I find.
For people who can't throw away anything that may still be heaven. I feel underwhelmed though and will have to see if a drone mod gets me interested.

I’m guessing it’s another tool/utility item that might not actually have a governing perk.
