Robotic network

The robotic network was introduced with v0.8.0, which also added the Repair packs and Construction robots.

Roboports are the base of the robotic network. They cover an area of 50x50 tiles and if placed near enough together, they are connected and build one big robotic network. Robots can fly inside this network to every point covered by the roboports. Roboports are expensive in both: the crafting and the need for power.

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 containments to the roboports.

There can be many distincted Robotic networks; and so also many Logistic networks! Bots cannot fly from one network into another.

See Logistic network.

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.

See Repair.

Number of bots in a robotic network

The amount of robots per network is limited:

• the roboports don't have unlimited space.
• flying robots need energy and the charging points are limited.

See also this discussion.

So the number of bots in a network depends on these factors:

• 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 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.

Things you can do to optimize 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

To optimze it, you can

Research speed or cargo-stacksize.

greatly recommended

Add more bots to your network

This has the above disadvantage, that at some point you can't add more bots into your network, because they can't be charged fast enough anymore. You can then add more roboports! This is an expensive enhancement.

Decrease the average distance between the logistic chests

• avoid transport of great amounts raw-material. Use transport-belts for the "main-routes" of the bots. 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 effecitvity very strong, because then they fly half of the time empty.
• Split a big network into two and move the items between these networks with transport belts or trains (and requester/provider-chests).

Example

It's a very good idea to use a robotic network on a train station to unload the chests, which are filled by the inserters from the wagons into storage-chests. The logistic bots have enough time to recharge in the times, when the there are no trains.

But don't use it then, to transport the ore also to the furnaces. For that the belts are much more useful, because the furnaces have a very constant need of raw-material and for constant flow the belts are much more useful.

See this thread thread or this picture

This shows the flow:

Wagon ---Inserter---> Provider chest ---Logistic bot---> Storage- or Requester-chest

Requester-Chest ---Inserter---> Belt ---> to the furnaces

No energy left

As of 0.8.5, robots with no energy are destroyed leaving nothing behind. Carried items are also destroyed.
