PS: Sorry for my English
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!:
If you feel like using any other location, you can, but that chapter is the easiest one to use.
You can get this achievement the fastest if you have the maximum of 3 scavenger bots. Some people have said you can have 5 with DLC or something like that. You can look it up or read the comments on other guides if you want to try that.
If you've placed scavenger bots throughout the story and collected them, you'll likely have some progress towards this achievement. You can check it by pressing , selecting achievements and scrolling down to "Metal Detector". You need to equip the bot, then walk towards the direction where it points you. If you're in Chapter 13's beginning like GnarlyDannyBoy mentioned, you'll just have to walk a few feet behind you. When the screen has a flashing full blue circle on it, you can deploy your bot. You have successfully struck a resource area.
If you follow the method above, you can deploy all 3 bots and play another mission or do something else to pass the time until they all come back to the Bench. Repeat this process until the achievement's tracker reaches 15/15. Once you reach this value, you'll get the achievement.
Here are the locations of each scavenger bot in the game:
Chapter 4: "History's Ember":
You'll find this naturally through the story as you climb down a ladder.
Chapter 8: "Off the Grid":
After a cutscene of the Hydra, you should keep walking forward past a couple large pipes and a ladder until you reach a couple metal barriers in a camp like area. If you walk through the path they form, you will come to a room. You'll find the bot next to an audio log in the room. The audio log is hard to miss. It shines bright blue in the darkness. You're required to go here to progress the story.
Chapter 13: "Off the Grid":
After climbing a wall with necromorphs, you'll come to a room where you'll be ambushed my wasters, exploders and some other enemies. After dealing with them, follow the objective until you see a fork in the path. Take the path to the left to find a SCAF artifact and the bot you're looking for. The bot itself will be in the far corner of the room. You'll see four closely packed little lights on the ground.
To deploy a bot, you hit to equip it. You then hit to bring up a screen on the bot itself and then to release it into an area.
You will want to follow the directions on the screen to a "Resource Area". You can technically release the bot anywhere you want, but for the trophy, it must be in specific spots that are littered throughout the game. The directions are fairly vague, as in sometimes you will need to up, down or just plain walk forward.
You will know if you are in a resource area when a bullseye shows on the screen. That is your cue to deploy the bot.
You’ll be introduced to the Scavenger Bot in Chapter 5. You can deploy these bots anywhere and it will scavenge the area for resources, and after a while it will be retrievable from any workbench. However, in order to fulfill the conditions of this trophy, you will need to deploy the Bots in specific locations by following the visual cues by pressing when you have the Scavenger Bot equipped. The arrows on the sides will tell you if you need to go up or down a level (arrows pointing up or down), or maintain your current level (arrows pointing towards the middle). The cone in the middle will tell you the direction that you need to go. When you’re at the specified location, the cone will turn into blue circles. Press to deploy and repeat this 15 times.
