Using trackers#
Trackers in PyLabRobot are objects that keep track of the state of the deck throughout a protocol. Two types of trackers currently exist: tip trackers (tracking the presence of tips in tip racks and on the pipetting channels) and volume trackers (tracking the volume in pipetting tips and wells).

Tip trackers#
The tip tracker is a simple class that keeps track of the current tip, and the previous operations that have been performed on an object. This enables features like return_tips() and automated tip type detection.
Initializing tip racks#
Whether or not tip tracking is turned on, spots on a tip rack initialize with a tip tracker that defaults to having a tip. The tip tracker only comes into play with performing operations.
tip_carrier[0] = tip_rack = HTF_L(name="tip rack")
tip_rack.get_item("A1").tracker.has_tip
True
To initialize a tip rack without tips, pass with_tips=False:
tip_carrier[1] = empty_tip_rack = HTF_L(name="empty tip rack", with_tips=False)
empty_tip_rack.get_item("A1").tracker.has_tip
False
To “empty” a tip rack after initialization, use the empty() method. To “fill” a tip rack after initialization, use the fill() method.
empty_tip_rack.fill()
empty_tip_rack.get_item("A1").tracker.has_tip
True
empty_tip_rack.empty()
empty_tip_rack.get_item("A1").tracker.has_tip
False

Tip tracker errors#
The tip tracker is most useful for catching hardware errors before they happen. With tip tracking turned on, the following errors can be raised:
from pylabrobot.resources.errors import HasTipError, NoTipError
NoTipError when picking up a tip#
This error is raised when the tip tracker is trying to access a spot that has no tip.

As expected: Channel 0 already has a tip.
Disabling the tip tracker#
The tip tracker can be disabled in three different ways, depending on the desired behavior.
Using a context manager#
The pylabrobot.resources.no_tip_tracking() context manager can be used to disable the tip tracker for a set of operations.
Note that we use the pylabrobot.liquid_handling.liquid_handler.LiquidHandler.clear_head_state() method to forget the tips that are currently mounted on the channels. This is needed because even though the tip tracker is disabled, the channels still keep track of the tips that are mounted on them.

Volume trackers#
The volume tracker is a simple class that keeps track of the current volume, and the previous operations that have been performed on an object. This enables features like automated liquid class selection in STAR, and raises errors before they happen on the robot.

Wells automatically initialize with a volume tracker that defaults to having no volume.
