Junk Bot/Drone to pick up salvage.

[Bugeisha]

Basically, something kind of like the eye bot that would fly around picking up random junk according to what you want... Could be a power armor mod or standalone Faux-follower or something.

Perhaps you could upgrade to be able to scrap stuff outside of settlement build zones.... like street lights, crates... etc...

That would require extensive scripting work, need the GECK
