In Arknights: Endfield, the “Tripod Central” mission sends you on a search for all of Copper’s Lost Robots scattered throughout Talos-II. While finding them all sounds daunting, the mission is broken down into smaller sections, letting you earn rewards for finding groups of robots one by one.
Okay, so when I started playing Arknights: Endfield, the first place I had to hunt down Lost Robots was The Hub in Valley IV. Luckily, there are exactly eight of them there β which is perfect, because thatβs how many you need for the first step of the “Tripod Central” quest. To save you some time running around, Iβve put together a list of all the Lost Robot locations in The Hub, along with how to solve any puzzles you find!
The Hub Lost Robot Location 1

You can find the first Lost Robot near Copper in The Hub, in the valley between Bridge Approach and Shorecove Camp. After defeating the Landbreakers in the area, talk to Copper to get the robot and begin the “Tripod Central” mission.
Solution
Here’s the puzzle solution for the first Lost Robot in The Hub.
The Hub Lost Robot Location 2

You can find the Lost Robot on the docks west of Copper, located between Bridge Approach and Shorecove Camp.
Solution
Here’s the puzzle solution for the second Lost Robot in The Hub.
The Hub Lost Robot Location 3

Okay, so I was looking for the third Lost Robot in The Hub, and it’s actually pretty close to Bridge Approach β just north of it. The fastest way I found was to fast travel to that TP Point in the Core AIC Area. Then, I headed west, up into the mining area, and jumped down right into the enemy camp. The robot’s tucked away down some stairs at the back of the camp, near the cliff. If you’re feeling confident and have enough Stamina in Arknights: Endfield, you can actually just sprint past all the enemies to get to it β that’s what I tried!

The Hub Lost Robot Location 8

Okay, so I finally tracked down the last Lost Robot in The Hub in Arknights: Endfield. It was tucked way up in the northeast corner of Southern Meadows, practically right next to where the Worker Dorms start. Took me a bit to find it way over there!
Solution
Here’s the first puzzle solution for the eighth Lost Robot in The Hub.βββββββ
And here’s the second solution.
After locating and solving the puzzles of eight Lost Robots (they don’t all need to be found in The Hub), find Copper in the Worker Dorms to claim your rewards, including Oroberyl for use in Arknights: Endfield Banners. Then, continue with the ‘Tripod Central’ mission. You can find more Lost Robots in areas like Valley Pass, Aburrey Quarry, Originium Science Park, Origin Lodespring, and Power Plateau.
