A complex machine capable of automatically crafting an item by taking the required items for it.
The crafter is to be placed next to a Conveyor Belt. When item passes through a belt next to the crafter, the crafter's robotic arms will go down and grab the item. As set by the crafter's GUI, the crafter will only grab blocks that it needs in order to craft an item. After it is done crafting an item, it will place it back into a specific conveyor belt.
