The Fully-Automated Loot Collector Organisational Robots (or FALCOR for short!) Beacons can be used in one two different modes.
If the Beacon was placed on the floor, then it will collect items within 16 metres in all directions and hold it until a MK1 FALCOR is free to collect.
If the Beacon was placed on top of a Storage Hopper, then it will collect items from that Storage Hopper and hold it until a Logistics FALCOR is free to collect.
FALCOR bases do not require power, however, Beacons do.
