Robot Leaf Cutter

The "Leaf Cutter" Robot is a Robot added by BuildCraft, which has the special ability to cut automatically leaves, for example to clear a forest and/or to gather leaves, while the player can do other things in the same time (see Usage). Subsequently the leaves can be collected by the "Picker" Robot and stored in a chest.

Usage


The robot automatically cuts leaves, as the name implies. It can be used to clear a forest and/or gather leaves. This is its special ability, so it will not collect the cut leaves. To automatically collect the leaves from the ground, the player needs a Picker Robot.

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

The following items are needed for the setup:
 * 4 Land Marks
 * 1 Chest
 * 1 Wooden 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 or more Shears
 * 1 "Leaf Cutter" Robot
 * some Dirt and Ladders (amount dependent on the tree height)

Step 1: Define Work Zone
In the first step, the player must delimit the area in which the robot should cut the leaves. 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 clears every tree/forest as well as leaves which are included for decoration in a house.

The player must place three Land Marks in a 90° angle which defines the base of the forest. Now the player can right-click on one of the marks to active the red borders (shown in Picture 2) which displays the ground area of the work zone.

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

Now, the player must build, for example a dirt tower, over the mark in the center until the height where the last leaves are present.

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 (shown in Picture 3). If no red border appears, then the Land Marks don't stand in a 90° angel to each other.

To cut all leaves of the trees, the "Leaf Cutter" Robot needs a 3-dimensional zone which includes all leaves. If the player uses the 2-dimensional zone, which was defined with the three ground marks, the robot cuts only the leaves on the ground.

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 Wooden Transport Pipe, as well as a Docking Station and a Emerald AND Gate which can be placed anywhere on the gate (without disconnecting the chest).

In front of the Emerald Gate, the Lever, and in the chest, the shears, can be placed. Now the station should look like the example in Picture 4.

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 Picture 5. In the first and third row 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 picture 5, are explained in the following:

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

The sequence of rows has no meaning, but only what is in each row. In this example the first or second row may be the blank row.

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 Picture 6). 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 and put the map in the GUI of the Emerald Gate in the question slot in the third row ("Go to station" option).
 * 3) At least put a shear in one of the empty slots in the second row on the right side

Now the configuration should appear like in Picture 5 and the control station is configured.

Step 4: Start and Stop
In the fourth and last step, the "Leaf Cutter" Robot can be placed on top of the Docking Station (shown in picture 7). At first the robot does nothing because the function in the third 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 first and the second row is active.

After a short time (the update time of the robot), the robot will take a shear out of the chest (second row in the Emerald Gate) and start the work in the defined zone (first row in the Emerald Gate) (shown in picture 8) until there are no leaves in the zone more.

When all leaves are cut in the defined working area, the robot automatically returns to the control station. But he still active and will start again to work, when new leaves are placed or appear in the working area. 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 he returns back to station automatically.

Recharging
If the robot is low on energy, then the player can destroy the robot with a punch or any tool/weapon till the robot drops as item on the ground. This maybe needs some more or less punchs, depending on the energy that the robot has been stored. Now 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.
