Robot Harvester

The "Harvester" Robot is a Robot added by BuildCraft, which has the special ability to harvest all types of plants (for example: grass, flowers, and wheat; see Usage), which can subsequently be used in combination with the "Farmer", "Planter" and "Picker" for an automatic farm. In the same time the player can do other things.

Usage


The robot automatically harvests all types of plants, which is its special ability. It can be used to operate an automatic farm.

The setup to start this work is a little bit complicated, but is explained step by step on the example location which is shown in Fig. 1.

The following items are needed for the setup:
 * 3-4 Land Marks
 * 1 Stone Transport Pipe
 * 1 Docking Station
 * 1 Emerald AND Gate (or a other type of Emerald Gate if special functions needed)
 * 1 Lever
 * 1 Map Location
 * 1 "Harvester" Robot
 * some Dirt and Ladders (amount dependent on the height of theworking area)

Step 1: Define Work Zone
In the first step, the player must delimit the area in which the robot should harvest the wheat. This is achieved with Land Marks. If the player doesn't define a working area and configured it in Step 3, then the robot works but wants to fly in every active chunk around the player and harvests every grass and flower.

The player must place three Land Marks in a 90° angle which defines the base of the farm. Now the player can right-click on one of the marks to active the red borders (shown in Fig. 2) which displays the ground area of the work zone. Like shown in the figure, the Land Marks must stand one block deeper, and not on top of the surface, to include the surface blocks.

The two marks on the left and top in the figure may not be more than 64 blocks away from the center mark in the right corner.

If the fields have multiple levels, then the player must build a dirt tower, over the mark in the center until up to the level where wheat also grows. On top of the dirt tower, the player must place the fourth Land Mark. If the player now right-click on any Land Mark, then a red border should be appear which frames a 3-dimensional work zone. If no red border appears, then the Land Marks don't stand in a 90° angel to each other.

To harvest on all hight levels in the respective area, the "Harvester" Robot needs a 3-dimensional zone which includes all growing wheat. If the player uses the 2-dimensional zone, which was defined with the three ground marks, the robot only harvests on the gorund level. Each wheat, grass or flower outside the working area is not touched.

Step 2: Control Station
In the second step, the player must build up the control station of the robot. It can be placed anywhere but it is recommend to place it in the near. The following explained control station is a minimum example and can be extended.

The station includes a Chest, with a connected Stone Transport Pipe, as well as a Docking Station and a Emerald AND Gate which can be placed anywhere on the gate. The Chest isn't required for usage and only for a better view of the Transport Pipe.

In front of the Emerald Gate, the Lever can be placed. Now the station should look like the example in Fig. 3.

Step 3: Configuration
The third step is the configuration of the Emerald Gate to control the robot. Also here, this example isn't the only system that works and can be extended.

The player must open the GUI of the Emerald Gate with a right-click, which shows two configurable blocks (one left, one right).

Select all the options as shown in Fig. 4. In both rows on the right side is a question mark determining whether the options before are selected. That means that something must be put in this slots.

Now only the important configurations to control the robot, which are shown in Fig. 4, are explained in the following:

A full explanation of all possible functions can be found in the article of the Emerald Gate.

The sequence of rows has no meaning, but only what is in each row. In this example the rows can also be the other way around.

The option previously required coordinates which must be added by the Map Location.
 * 1) Take the Map Location and right click on one of the Land Marks to receive the coordinates of the working zone (shown in Fig. 5). The Map Location should now have a rectangle on the item. Now this map must be placed in GUI of the Emerald Gate in the "question slot" in the first row ("Working area" option). The Map Location should remain stored, and can be reused for the second coordinates.
 * 2) Take the Map Location again and right-click on the Docking Station to receive the coordinates. Note: Here it is important, which side is indicated at the coordinates for the docking station. This is displayed in the player inventory if the cursor is moved on the Map Location. Please check if the specified side is the same where the docking station is, for example UP if the docking station is on the upside of the pipe. Now put the map in the GUI of the Emerald Gate in the question slot in the third row ("Go to station" option).

Now the configuration should appear like in Fig. 4 and the control station is configured. The Land Marks and the respective frame are now not longer needed for this example and can be removed. If you want to use the frame for other robots (for example for the "Picker", make sure you have the coordinates stored in a Map Location.

Step 4: Start and Stop
In the fourth and last step, the "Harvester" Robot can be placed on top of the Docking Station (shown in Fig. 6). At first the robot does nothing because the function in the first row commands the robot to stay on the station.

If the Lever in front of the gate is switched and a redstone signal receives the gate, the second row is active.

After a short time (the update time of the robot), the robot will start the work in the defined zone (second row in the Emerald Gate) (shown in Fig. 7) until there are no plants in the zone more, which can be harvested. The items, for example Wheat and Seeds are dropped on the ground and can be collected by the player or the "Picker" Robot.

When all plants are harvested in the defined working area, the robot automatically returns to the control station. But it still active and will start again to work, when new wheat is grown. The work of the robot can be stopped anytime by switching the lever (in front of the gate) off. When the robot is currently at work, then it returns back to station automatically.

Recharging
If the robot is low on energy, it will begin to seek out a kinesis pipe with a docking station to charge itself. If none are available, it will continue doing its job until its battery dies. The player can also stop the robot with attacks to prematurely drain its battery, causing the to robot drop as item on the ground. Stronger attacks will drain its battery faster. The player can pick up the robot and place in the Charging Table to recharge it. After that, the robot can be placed again on the Docking Station and is again ready to work.
