The "Tripod Central" mission in Arknights: Endfield tasks you with hunting down all of Copper's Lost Robots across the entirety of Talos-II. A big ask, but the mission is thankfully split into many parts, so you get rewards for locating small batches of robots at a time.
The first area you'll likely find Lost Robots in is The Hub in Valley IV, which conveniently contains eight robots — the exact number you need to find in order to complete the first part of "Tripod Central" in Arknights: Endfield. To speed your search along, we have all The Hub Lost Robot locations and puzzle solutions listed below.

The robot is down some stairs at the back of this camp, by the cliff edge. If you have enough Stamina in Arknights: Endfield, you might be able to run past the enemies without having to engage them.
