Logistic robot

Logistic robot is the flying robot that transports items between logistic chests inside a logistic network and is the mobile element of Logistics in Factorio. Logistic robots operate only within the coverage area provided by Roboports; Roboports that overlap form a single logistic network. Robots repeatedly return to a Roboport to recharge when their energy is low.

A logistic robot carries items between logistic chests according to the network’s rules and chest settings. The robot’s default cargo capacity is 1 item per trip; this capacity increases when the Worker robot cargo size technology is researched (up to the researched maximum). Logistic robots make items available to the logistic network by moving them from provider chests to requester or storage destinations and by placing items into requester chests when those chests request supplies.

The logistic network’s chests and their interactions with robots:

• Active provider chest: pushes its stored items into the logistic network so robots may take them. Logistic robots do not store items into active provider chests.
• Passive provider chest: its stored items are made available to the network for retrieval. Logistic robots do not store items into passive provider chests.
• Storage chest: holds surplus items that are not currently requested; it can be filtered to store only one item type and makes its contents available to the network.
• Requester chest: requests specific items and receives deliveries from logistic robots. Robots will place items into requester chests but will not remove items from them.
• Buffer chest: functions as both a requester and a passive provider. Buffer chests always have the next priority after requester chests for deliveries.
• Other logistic-enabled entities can be configured to interact with logistic requests (for example, space platform related entities in the Space Age content send/receive logistic requests to and from special surfaces).

The logistic network can be integrated with the Circuit network by connecting Roboports or logistic chests with Red wire or Green wire; this allows automation and conditional control of logistic behavior where supported.

Practical notes:

• Place Roboports so their coverage areas overlap to create a single, large logistic network and to provide enough charging capacity for robots.
• Research Worker robot cargo size early if you rely on long transport routes or high-throughput deliveries; each increment increases the number of items a robot can carry per trip.
• Use Active and Passive provider chests to feed the network, Storage chests to hold excess, and Requester chests to pull specific supplies into production trains or assemblers.
• Buffer chests are useful as local staging points: they request items and immediately allow others to pull from their stored items.
• Connect logistic chests or Roboports to the Circuit network with Red wire or Green wire when you need conditional supply, thresholds, or integration with logistic request signals.
