In Factorio every item on screen is a real object in memory and follows the rules of the [[Game engine]]. For simulation games, this is not typical; it&#039;s much more common to generalize. Best examples are the older versions of SimCity, where the the simulation doesn&#039;t simulate every inhabitant of the city.&lt;br /&gt;
&lt;br /&gt;
The reason for that is just CPU-performance. Real-time game-physics for up to 100,000 of objects at the same time is not typical for a simulation game. And the Factorio [[Game engine]] creates an exact and reproducible simulation of the Factorio world and it is so exact, that it can be used, to measure some astonishing behavior of belts.&lt;br /&gt;
&lt;br /&gt;
== What to measure ==&lt;br /&gt;
Some things can be measured for belts:&lt;br /&gt;
* &#039;&#039;&#039;Length&#039;&#039;&#039; (or area). Items have a collision box of 0.28 x 0.28 [[tile]]s. So 10 items laying in a single row on a belt, non moving, take length of 2.8 tiles.&lt;br /&gt;
* &#039;&#039;&#039;Speed&#039;&#039;&#039;. The speed of items on a belt is measured for practical reasons in tiles/sec or tiles/min. Note, that internaly it&#039;s measured in tiles per tick (1/60 sec)&lt;br /&gt;
* &#039;&#039;&#039;Density&#039;&#039;&#039;. See length. The density is how many items can lay on a tile or in conjuction with belts: how many items can lay in a row/lane. There are in average 3.571 items per lane or 7.143 on a tile of belt (=2 lanes). But the density differs depending on standing still or moving - read further!&lt;br /&gt;
* &#039;&#039;&#039;Throughput&#039;&#039;&#039;. How many items per minute are moved from one tile to the next. Measured in items/sec or better items/min.&lt;br /&gt;
&lt;br /&gt;

We assume here, that the density of items is always equal, so the transported amount should reflect the speed.&lt;br /&gt;

&lt;br /&gt;
== Comments to the results ==&lt;br /&gt;
&lt;br /&gt;
The first surprising result is, that the theoretic throughput differs from real measured. Too much to be just measurement errors.The second result is, that the more speed a belt has, the more ineffective it becomes. That is in the first moment not clearly explainable. The awaited result is, that a fast belt can transport exactly the double amount of items, than a basic, because it is double as fast (1.875 tiles/sec vs. 3.75 tiles/sec).&lt;br /&gt;
&lt;br /&gt;
The reason for this difference is the distance of the items on the belt when running. Items on the belt cannot run completely compressed, they need a small distance. This is the same problem as in a traffic jam: You cannot drive, when the first car drives, you need to wait until the car before you drives and then you have a reaction-time of about 1/2 second before yourself begin to drive. The same is it with the items on the belt and the reaction-time here is 1/60 or one tick [currently not really validated, but not more than 2 ticks; this can be calculated by measuring how fast the standing wave goes through the items (needs to built a very complicated testing factory)]. You can see this reaction time running through your items as a standing wave, when you have a belt, which is completely filled and only sometimes an item is removed. When you compare the speed of this standing waves, you can see clearly, that they are the same speed for all types of belts.&lt;br /&gt;
&lt;br /&gt;
The reaction-distance for items on a basic belt is&lt;br /&gt;
  (1.875 tiles/sec) / 1 tick = 1.875 tiles/sec / 1/60 sec = 0.031125 tiles&lt;br /&gt;
or in other words: An item on a moving belt is not 0.28 tiles long, it is 0.31125 tiles, which makes it 11.2% longer&lt;br /&gt;
&lt;br /&gt;
Overview for all belts:&lt;br /&gt;
  Basic:   0.28 tiles + 0.03125 tiles = 0.31125 tiles =&amp;gt; 11.2%&lt;br /&gt;
  Fast:    0.28 tiles + 0.0625 tiles  = 0.3425 tiles  =&amp;gt; 22.3%&lt;br /&gt;
  Express: 0.28 tiles + 0.09375 tiles = 0.37375 tiles =&amp;gt; 33.5%&lt;br /&gt;
This explains the reduction to 90% of speed for basic belt and the 74% for the fast belt (all inside measuring errors), but doesn&#039;t explain the results for express belt. This is part of further research.&lt;br /&gt;
&lt;br /&gt;
This shows clearly, that the faster a belt is, the more distance the items have on a moving belt. More distance means, the density is lighter and this means, there are not so many items transported.&lt;br /&gt;
&lt;br /&gt;
(This may explain the discrepancy in transported items, but don&#039;t use the numbers for real calculations, because they need to be redone!)&lt;br /&gt;
(This is eventually one reason: http://www.factorioforums.com/forum/viewtopic.php?f=8&amp;amp;t=3630 )&lt;br /&gt;

&lt;br /&gt;
== Comments to the results ==&lt;br /&gt;
&lt;br /&gt;
The first surprising result is, that the theoretic throughput differs from real measured. Too much to be just measurement errors.The second result is, that the more speed a belt has, the more ineffective it becomes. That is in the first moment not clearly explainable. The awaited result is, that a fast belt can transport exactly the double amount of items, than a basic, because it is double as fast (1.875 tiles/sec vs. 3.75 tiles/sec).&lt;br /&gt;
&lt;br /&gt;
The reason for this difference is the distance of the items on the belt when running. Items on the belt cannot run completely compressed, they need a small distance. This is the same problem as in a traffic jam: You cannot drive, when the first car drives, you need to wait until the car before you drives and then you have a reaction-time of about 1/2 second before yourself begin to drive. The same is it with the items on the belt and the reaction-time here is 1/60 or one tick [currently not really validated, but not more than 2 ticks; this can be calculated by measuring how fast the standing wave goes through the items (needs to built a very complicated testing factory)]. You can see this reaction time running through your items as a standing wave, when you have a belt, which is completely filled and only sometimes an item is removed. When you compare the speed of this standing waves, you can see clearly, that they are the same speed for all types of belts.&lt;br /&gt;
&lt;br /&gt;
The reaction-distance for items on a basic belt is&lt;br /&gt;
  (1.875 tiles/sec) / 1 tick = 1.875 tiles/sec / 1/60 sec = 0.031125 tiles&lt;br /&gt;
or in other words: An item on a moving belt is not 0.28 tiles long, it is 0.31125 tiles, which makes it 11.2% longer&lt;br /&gt;
&lt;br /&gt;
Overview for all belts:&lt;br /&gt;
  Basic:   0.28 tiles + 0.03125 tiles = 0.31125 tiles =&amp;gt; 11.2%&lt;br /&gt;
  Fast:    0.28 tiles + 0.0625 tiles  = 0.3425 tiles  =&amp;gt; 22.3%&lt;br /&gt;
  Express: 0.28 tiles + 0.09375 tiles = 0.37375 tiles =&amp;gt; 33.5%&lt;br /&gt;
This explains the reduction to 90% of speed for basic belt and the 74% for the fast belt (all inside measuring errors), but doesn&#039;t explain the results for express belt. This is part of further research.&lt;br /&gt;
&lt;br /&gt;
This shows clearly, that the faster a belt is, the more distance the items have on a moving belt. More distance means, the density is lighter and this means, there are not so many items transported.&lt;br /&gt;
&lt;br /&gt;
(This may explain the discrepancy in transported items, but don&#039;t use the numbers for real calculations, because they need to be redone!)&lt;br /&gt;
(This is eventually one reason: http://www.factorioforums.com/forum/viewtopic.php?f=8&amp;amp;t=3630 )&lt;br /&gt;

In Factorio every item on screen is a real object in memory and follows the rules of the [[Game engine]]. For simulation games, this is not typical; it&#039;s much more common to generalize. Best examples are the older versions of SimCity, where the the simulation doesn&#039;t simulate every inhabitant of the city.&lt;br /&gt;
&lt;br /&gt;
The reason for that is just CPU-performance. Real-time game-physics for up to 100,000 of objects at the same time is not typical for a simulation game. And the Factorio [[Game engine]] creates an exact and reproducible simulation of the Factorio world and it is so exact, that it can be used, to measure some astonishing behavior of belts.&lt;br /&gt;
&lt;br /&gt;
== What to measure ==&lt;br /&gt;
Some things can be measured for belts:&lt;br /&gt;
* &#039;&#039;&#039;Length&#039;&#039;&#039; (or area). Items have a collision box of 0.28 x 0.28 [[tile]]s. So 10 items laying in a single row on a belt, non moving, take length of 2.8 tiles.&lt;br /&gt;
* &#039;&#039;&#039;Speed&#039;&#039;&#039;. The speed of items on a belt is measured for practical reasons in tiles/sec or tiles/min. Note, that internaly it&#039;s measured in tiles per tick (1/60 sec)&lt;br /&gt;
* &#039;&#039;&#039;Density&#039;&#039;&#039;. See length. The density is how many items can lay on a tile or in conjuction with belts: how many items can lay in a row/lane. There are in average 3.571 items per lane or 7.143 on a tile of belt (=2 lanes). But the density differs depending on standing still or moving - read further!&lt;br /&gt;
* &#039;&#039;&#039;Throughput&#039;&#039;&#039;. How many items per minute are moved from one tile to the next. Measured in items/sec or better items/min.&lt;br /&gt;
&lt;br /&gt;

|The fast belt with express edge seems to be faster, than pure express belt!&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
== Comments to the results ==&lt;br /&gt;
&lt;br /&gt;
The first surprising result is, that the theoretic throughput differs from real measured. Too much to be just measurement errors.The second result is, that the more speed a belt has, the more ineffective it becomes. That is in the first moment not clearly explainable. The awaited result is, that a fast belt can transport exactly the double amount of items, than a basic, because it is double as fast (1.875 tiles/sec vs. 3.75 tiles/sec).&lt;br /&gt;
&lt;br /&gt;
The reason for this difference is the distance of the items on the belt when running. Items on the belt cannot run completely compressed, they need a small distance. This is the same problem as in a traffic jam: You cannot drive, when the first car drives, you need to wait until the car before you drives and then you have a reaction-time of about 1/2 second before yourself begin to drive. The same is it with the items on the belt and the reaction-time here is 1/60 or one tick [currently not really validated, but not more than 2 ticks; this can be calculated by measuring how fast the standing wave goes through the items (needs to built a very complicated testing factory)]. You can see this reaction time running through your items as a standing wave, when you have a belt, which is completely filled and only sometimes an item is removed. When you compare the speed of this standing waves, you can see clearly, that they are the same speed for all types of belts.&lt;br /&gt;
&lt;br /&gt;
The reaction-distance for items on a basic belt is&lt;br /&gt;
  (1.875 tiles/sec) / 1 tick = 1.875 tiles/sec / 1/60 sec = 0.031125 tiles&lt;br /&gt;
or in other words: An item on a moving belt is not 0.28 tiles long, it is 0.31125 tiles, which makes it 11.2% longer&lt;br /&gt;
&lt;br /&gt;
Overview for all belts:&lt;br /&gt;
  Basic:   0.28 tiles + 0.03125 tiles = 0.31125 tiles =&amp;gt; 11.2%&lt;br /&gt;
  Fast:    0.28 tiles + 0.0625 tiles  = 0.3425 tiles  =&amp;gt; 22.3%&lt;br /&gt;
  Express: 0.28 tiles + 0.09375 tiles = 0.37375 tiles =&amp;gt; 33.5%&lt;br /&gt;
This explains the reduction to 90% of speed for basic belt and the 74% for the fast belt (all inside measuring errors), but doesn&#039;t explain the results for express belt. This is part of further research.&lt;br /&gt;
&lt;br /&gt;
This shows clearly, that the faster a belt is, the more distance the items have on a moving belt. More distance means, the density is lighter and this means, there are not so many items transported.&lt;br /&gt;
&lt;br /&gt;
(This may explain the discrepancy in transported items, but don&#039;t use the numbers for real calculations, because they need to be redone!)&lt;br /&gt;
(This is eventually one reason: http://www.factorioforums.com/forum/viewtopic.php?f=8&amp;amp;t=3630 )&lt;br /&gt;

&lt;div&gt;Logistic robots are autonomous floating devices capable of transporting resources in the [[Logistic network]].&lt;br /&gt;
&lt;br /&gt;
Logistic robots are one of the priority targets of [[Biter]]s, meaning they will engage them even if there are [[Pollution]]-producing buildings around. Since logistic robots have no means of defending themselves or even escaping, they get destroyed very quickly.&lt;br /&gt;
&lt;br /&gt;
Upgrades for logistic bots enhance their speed and the number of items carried at a time (starts at 1).&lt;br /&gt;

Gun turrets are very basic defensive structures and the easiest way of automatic defense.&lt;br /&gt;
&lt;br /&gt;
* Gun turrets are your first defense weapon.&lt;br /&gt;
* They are cheap and ammunition can be refilled by [[Inserters]].&lt;br /&gt;
* You can fill the bullets into them by hand. But you should automate that, use a chest, a belt and some inserters to do that job constantly.&lt;br /&gt;
* They don&#039;t need any power to operate (only the inserters to fill them, but you can use burner inserter for that job), so they are not dependent to electricity.&lt;br /&gt;
* With upgrades (gun + turret defence upgrades) and [[Piercing rounds magazine]] gun turrets are a much harder weapon, than laser turrets &#039;&#039;&#039;( [http://www.factorioforums.com/forum/viewtopic.php?f=16&amp;amp;t=4363&amp;amp;start=20 see thread])&lt;br /&gt;
* Gun turrets are always sized 1x2 even when rotated which makes them somewhat problematic to use with rotated [[Blueprint]]s. It is no problem to mirrow the blueprint, but when rotated by 90° they may &#039;overwrite&#039; an inserter or let one tile free between them. To workaround this use two blueprints, one for north-south and one for west-east usage.&lt;br /&gt;

[[File:Defender-usage.gif|frame|right|Defender being spawned and following the player.]]&lt;br /&gt;
A basic capsule which, when used, will spawn a single Defender robot. &lt;br /&gt;
The Defender has infinite ammunition and will follow the player, attacking any enemies that come within range, until it is destroyed or its lifespan elapses. To use; place the capsule in a quick-bar slot and press the corresponding quick-slot key. The capsule will fly to the position of the cursor and deploy. &lt;br /&gt;
&lt;br /&gt;
== Strategy ==&lt;br /&gt;
Follower robots will only loosely follow the player and are subject to inertia. This allows the player to &#039;swing&#039; packs of follower robots into enemy bases to damage enemy structures with less risk to himself. Launching [[Distractor capsule]]s into the enemy base, as well as using the speed of the [[Car]] or [[Basic exoskeleton equipment]] can further reduce damage to the player.  &lt;br /&gt;
&lt;br /&gt;
== Count Limit ==&lt;br /&gt;
[[File:Robot-Count.png|225px|thumb|right]]The maximum number of active Defender robots is limited by the [[Follower robot count]] research. While using follower robots, the number of robots in-use will be visible on an icon to the right of the quick-bar. Hovering over the icon with the cursor will show the types of robots and the currently researched maximum.&lt;br /&gt;

[[File:Defender-usage.gif|frame|right|Defender being spawned and following the player.]]&lt;br /&gt;
A basic capsule which, when used, will spawn a single Defender robot. &lt;br /&gt;
The Defender has infinite ammunition and will follow the player, attacking any enemies that come within range, until it is destroyed or its lifespan elapses. To use; place the capsule in a quick-bar slot and press the corresponding quick-slot key. The capsule will fly to the position of the cursor and deploy. &lt;br /&gt;
&lt;br /&gt;
== Strategy ==&lt;br /&gt;
Follower robots will only loosely follow the player and are subject to inertia. This allows the player to &#039;swing&#039; packs of follower robots into enemy bases to damage enemy structures with less risk to himself. Launching [[Distractor capsule]]s into the enemy base, as well as using the speed of the [[Car]] or [[Basic exoskeleton equipment]] can further reduce damage to the player.  &lt;br /&gt;
&lt;br /&gt;
== Count Limit ==&lt;br /&gt;
[[File:Robot-Count.png|225px|thumb|right]]The maximum number of active Defender robots is limited by the [[Follower robot count]] research. While using follower robots, the number of robots in-use will be visible on an icon to the right of the quick-bar. Hovering over the icon with the cursor will show the types of robots and the currently researched maximum.&lt;br /&gt;
