The robotic network was introduced with v0.8.0, which also added Repair packs and Construction robots. Roboports are the base of the robotic network. They cover an area of 50x50 tiles and, if placed near each other, connect to build one big robotic network. Robots can fly inside this network to every point covered by the roboports. Roboports are expensive both to craft and to power.

Robots

Main article: Robots

Robots perform any required functions within their coverage area. They need power to keep flying. When they have nothing to do, they fly to the nearest roboport to sleep and recharge.

Roboports

To create a robotic network, you need to place one Roboport. If you place a second, lines will show you if it is connected with the first. If so, they create a bigger network. The roboports are also used to charge bots. See below if you have charging problems.

Avoid "angeled" shaped layouts of roboports!

This is a know issue: robots always take the shortest path. This means they can and will fly over areas without roboport-coverage! The distance to the chargers may be too far, and such a layout will slow down the robots significantly.

Logistic network

Main article: Logistic network

The area covered by the robotic network is identical to that of the Logistic network. All Logistic network/Chests inside a robotic network are connected and build the Logistic network. Imagine the logistic chests send their contents to the roboports. There can be many individual Robotic networks. Bots cannot fly from one network to another.

Repair

Main article: Repair

All broken entities will be repaired with Repair packs by the Construction robots. Destroyed entities will be replaced, if they are available in the same logistic network.

Number of bots in a robotic network

The number of robots per network is limited because roboports have limited space to charge flying robots. So the number of bots in a network depends on:

  • the number of roboports
  • the average distance between the roboports (density)
  • the form of the robotic network/placement of the ports
  • average distance the logistic bots fly between Logistic network/Chests
  • how much damage the Construction robots must repair and how often they need to place or remove buildings

And in general:

  • number of bots flying
  • number of bots stored in roboports

As a rule of thumb between 50-100 bots per Roboport is possible.

Optimizing a robotic network

The transportation-power of the logistic bots is nearly constant! It depends on

  • Speed of the bots
  • Cargo-stacksize (number of items he can take)
  • Number of bots
  • Average distance between your chests (all combinations)
  • How often they fly empty (the more "random" the transport is the better, because then there is a bigger chance that an empty robot is near!)
  • How long they need to wait for recharge - this effect is "blocking", which means that up to an unknown maximum, the transport-power is constant. But, if the waiting queue gets too long, the system falls apart, which means that, counter-intuitively, a slightly lower number of bots is actually more efficient/faster!

To optimize it, you can

Research speed or cargo-stacksize.
greatly recommended
Add more bots to your network
but be careful not to exceed the magical limit mentioned above.
Add more roboports at strategic points
This is an expensive enhancement and sometimes doesn't help, but can solve the problem
Decrease the average distance between the logistic chests
  • avoid transporting a lot of raw material - instead use transport belts for items with a lot of throughput. Bring the big material flows as near to the target as possible. The transport-power of logistic bots is much bigger than belts, but a constant flow reduces their effectiveness by about half, because they fly empty about half the time.
  • Split a big network in two and move items between them with transport belts or trains (and requester/provider-chests).

Example

It's a very good idea to use a robotic network at a train station to unload the chests that have been filled by the inserters from the wagons. The logistic bots have enough time to recharge between trains. But don't also use them to transport the ore to the furnaces. For that the belts are much more useful, because the furnaces have a constant need for raw material and for constant flow belts are much more useful. This shows the flow:

Wagon ---Inserter---> Provider chest ---Logistic bot---> Storage- or Requester-chest
Requester-Chest ---Inserter---> Belt ---> to the furnaces

Energy

Robots with no energy will slow down to a 5th of normal speed.

Choosing the post for charging

Normally a robot flies to the nearest roboport to recharge. If the queue on that roboport is too long, he eventually choose another port. This is specified by the ratio of

<distance to different roboport in tiles> / <queue size of robots waiting>

Currently, to choose the more distant roboport, the distance must be at most

<Number of robots in the queue and on the way> / 2

So to choose a roboport that is 10 tiles more distant, it has to have 20 less robots waiting in the queue.
