This is a structure that you can build in your settlement that houses a single, autonomous Eyebot that will scout for components, ammo, or explosives. You can get the blueprint for this structure in the Mechanist's quarters in his lair. This structure requires 6 power to run so if you'll build multiple pods, make sure it has access to a good power source or generator series.
Deployment
To send an eyebot to scout for your selected item, access the pod's terminal then select the desired item. Once the Eyebot has located the item, you'll get a notification and the location where you can collect the resources will be marked under Miscellaneous Quests in your Pip-Boy. Head to the location where you get pointed and follow the quest marker. Once you located the marked container, the eyebot will return to its pod and you can deploy it again.
