Automation
Automation is the technique of making a certain process operate with little to no input from the player. You can take things like mining, farming, and base building to the next level using the Electronics and Automation tables in Core Keeper. All electronics require a power source, usually in the form of a lever or generator, to function, and from there it’s just a case of setting up the right circuitry to achieve the desired effect.
Electricity[edit]
Most machineries require electricity to function. It can then be spread around either by using 
Electrical Wire or by placing a machine next to another electrically charged machine. Once a machine is powered, notches on the four sides of the base of the machine will glow yellow.
The following items generate electricity:
The following machines require electricity to function:
The following items change the flow of electricity:
Electricity is transmitted at full power over a path length of up to 18 conducting tiles from an Electricity Generator, 6 from a Lever or Pressure Plate. It will then fall off in power level over a further length of 5 tiles, causing connected lamps to illuminate less brightly. All machines decrease the transmitted power level by one, as a tile of wire would.
Drills, Arms and Doors all work normally at any power level. Delay Circuits will pass along a lower powered signal. As will Logic Circuits, unless they have a higher power level on another input. In this way, they can act as a relay, boosting the power of a signal. Levers are player activated switches that will pass through generator's higher power signal, as well as generating their own power.
Automatic Door[edit]
Pop a pair of 
Pressure Plate on both sides of an 
Electrical Door to make a door that automatically opens from whatever side you approach. 
Explorer Proximity Sensor or 
Electrical Drop Gate could also be used to upgrade the door.
Boulder Excavation[edit]
Grab an electricity generator, some Electrical Wire and set up a collection of 
Crude Drill or 
Drill around an Ore Boulder to start
mining. You can use 
Conveyor Belt, 
Robot Arm, or Furnaces to upgrade the setup.
Examples of Ore Boulder mining setups. The 8-drill example automatically smelts Scarlet Ore into bars.
Wood Farm[edit]
A way to generate an infinite supply of Wood!
Root Seeds produce wood in a random direction every 2-3 minutes and the idea is that Drills will harvest one tile that the Root Seed can grow Wood into, so it is important to make sure no two Drills are facing the same tile (just make sure your Drills aren’t touching the actual Root Seeds, otherwise you’ll destroy the entire plant).
Example of a simple extendable automated Wood farm grown from Root Seeds.
Advanced/Efficient Setup[edit]
While the simple setup is easy to implement, it is not high yielding. The following is a setup that utilizes the growing mechanics of roots for a much higher yield.
This advanced automation does require some setup work, as simply planting the roots and letting them grow can result in gaps in the roots, (as seen below) due to how root plants decide where to place the next growth. Roots will not grow directly beside any other root, so making sure they initially grow in straight lines is important. Because of this, it is helpful to start with a single root to frame the growth paths.
There are limitations in how far the roots from a single root plant can grow, so the main root plant system will need to be added part way through to complete the setup. Make sure these new root plants are planted strategically, so that they do not cause early wood growth further down that will create gaps and prevent complete growth of the roots. After the main root plant system is in place, the root plant used for framing can be removed if desired.
Using this method, much larger and higher yielding root farms can be planted.

Mob Farm[edit]
The basic setup for a mob farm requires a closed off area (usually around 16x16 tiles) that is covered with the material to spawn your required mob (
Fungal Soil to spawn 
Shrooman, for example). Set up traps such as 
Spike Trap, 
Galaxite Turret, or 
Radiation Crystal to kill the mobs and Robot Arms, Conveyor Belts, and Chests to collect their drops.
Example of a very small and inefficient manual mob farm that uses Chrysalis to spawn Larva, Big Larva and Cocoons, for their drops and ranged or melee experience.
Orange Slime farming can most easily be automated by placing any number of Spike Traps in their enclosure. Mobs mostly wander around randomly, and Slimes will aggro on any trap that hits them, causing them to jump on it repeatedly.
Food Farm[edit]
Players can combine 
Sprinkler, 
Robot Farm Arm, 
Seed Extractor, Conveyor Belt, and 
Conveyor Belt Splitter into a system that will automatically plants seeds and harvests crops when powered by electricity. Since the Robot Farm Arm will not generate seeds, half of the plants will need to be fed into a seed extractor. The other half can be collected to be used by the player or sent to another automatic system.
Logic Gates[edit]
If you wanna get into electronic circuits and advanced electronics, you need to learn the basics of logic circuits.
Here are all the different truth tables, and a picture representing all of them using the electronic blocks of the game:
