I found a spot that works really well in Chapter 12.
In the room with the giant alien carcass, there's a Bench right near an elevator that goes up to the catwalks above that have the harpoons you use to open the carcass. If you're facing the Bench, the door you want is just to your right. It will lead you to a small outside space with a Resource Area on your left literally a few yards from the door. Once you place the scavenger bot go back through the door and open the other side so it closes behind you.
After that just turn around and go back outside again. The area reloads and the Resource Area will be reset and you can place another bot. This eliminates having to quit out of the game and saves a lot of time.
Also as a bonus, just to the left of the spot where you set down the bots is a post/pillar with an unbreakable grey cube box next to it. Go over and look behind it. Initially there's an artifact here, but in subsequent passes, the game will drop in another random pick-up item: ammo clips, stasis pods, crafting materials, etc. However, it doesn't replace the item if you fail to pick it up and continues to add a new item each time you pass through this area. So keep checking this spot for additional resources.
I've made a video showing what I've described above. Hope it helps!:
