The Hub ‘Tripod Central’ Lost Robot Locations in Arknights Endfield

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 – which is perfect, because that’s how many you need for the first step of the “Tripod Central” quest. To save you some time running around, I’ve put together a list of all the Lost Robot locations in The Hub, along with how to solve any puzzles you find!
