11. A system, comprising:
a vessel holding a first liquid, wherein a liquid handling robot is configured to dispense a droplet of a second liquid into the first liquid according to a set of liquid handling parameters,
a camera configured to sample a set of images of the droplet; and
a computing system configured to:
detect the droplet in the set of images using a droplet model, wherein the droplet model distinguishes between air bubbles and liquid droplets; and
determine an estimated volume of the droplet based on the set of images using a volume characterization model.
