dismount_tool()

Dismounts the currently mounted tool into it’s assigned slot, taking into account the slot’s direction.

This function only applies to FarmBots with interchangeable tools, such as FarmBot Genesis.

-- Dismount the currently mounted tool
dismount_tool()

-- It is recommended to find home after dismounting tools
-- to stage FarmBot for future operations
find_home()

dispense(mL, params?)

Dispenses the given amount of liquid in milliliters. The params argument is optional and can be used to override the default tool_name of “Watering Nozzle” and the default pin of 8.

-- Dispense 100 mL of water using the default "Watering Nozzle" tool operated by pin 8
dispense(100)

-- Dispense 200 mL of fertilizer using a custom tool named "Fertigator" operated by pin 7
dispense(200, {tool_name = "Fertigator", pin = 7})

mount_tool(tool)

Mounts the given tool and pulls it out of its slot, taking into account the slot’s direction.

This function only applies to FarmBots with interchangeable tools, such as FarmBot Genesis.

-- It is recommended to find home before mounting tools
-- to ensure accuracy of movements
find_home()

-- Add a Location variable named "Tool" to the sequence
-- and select the tool you wish to mount
tool = variable("Tool")

-- Because tools themselves do not have coordinates, FarmBot
-- will look up which slot the chosen tool has been assigned
-- to and use the slot's coordinates in the mount_tool() function
mount_tool(tool)

verify_tool()

Verifies if a tool is mounted to the UTM by checking the UTM’s tool verification pin as well as the MOUNTED TOOL field in FarmBot’s state tree. Returns true if a tool is mounted or false if no tool is mounted.

This function only applies to FarmBots with interchangeable tools, such as FarmBot Genesis.

The verify_tool() functionality is built-in to the mount_tool() and dismount_tool() helpers.

-- Exit sequence if tool verification fails (no tool)
if not verify_tool() then
  return
end

water(plant)

Moves to and waters the given plant based on its age and assigned watering curve.

A plant’s age is calculated from its planted_at date and the current date. If a plant’s planted_at date is not set, try changing the plant’s STATUS to Planted from the frontend.

If using a FarmBot with interchangeable tools, such as FarmBot Genesis, you will need to first mount the watering tool before using the water() function.

-- Get the "Plant" variable from the sequence
plant = variable("Plant")

-- Water the plant based on its age and watering curve
water(plant)
