System and method for automated water heating and dispense cycles for brewing pour-over coffee

An automated boiler comprising:

• a container configured to seat on a prep surface and comprising:
• a water reservoir configured to transiently store a volume of water;
• a heating element configured to heat metered volumes of water received from the water reservoir;
• a temperature sensor configured to output a signal representing temperature of water exiting the heating element;
• and
• an outlet fluidly coupled to the heating element;
• a hose fluidly coupled to the outlet of the container;
• a nozzle fluidly coupled to the hose, opposite the outlet, and configured to transiently dispense volumes of water into a set of pour-over setups loaded with coffee grounds and arranged on the prep surface about the container;
• a set of sensors installed on the nozzle and configured to output signals corresponding to location of a pour-over setup on the prep surface;
• a lid flexibly coupled to the container and defining a slot;
• a positioner assembly arranged within the lid and comprising:
• a nozzle arm extending through the slot and defining a head configured to accept and retain the nozzle at a target height from the prep surface;
• and
• a set of positioner actuators configured to transiently drive translation of the nozzle arm;
• and
• a controller configured to:
• based on the signal output by the temperature sensor, selectively actuate the heating element to regulate temperature of water dispensed by the nozzle to within a threshold deviation of a target dispense temperature;
• interpret a first location of a first central axis of a first pour-over setup arranged on the prep surface based on a first signal output by the set of sensors;
• interpret a second location of a second central axis of a second pour-over setup arranged on the prep surface based on a second signal output by the set of sensors;
• selectively drive the set of positioner actuators to drive the nozzle across a first sequence of positions defined by a first target dispense pattern and the first location to dispense heated water into the first pour-over setup according to a first target dispense pattern;
• and
• selectively drive the set of positioner actuators to drive the nozzle across a second sequence of positions defined by a second target dispense pattern and the second location to:
• locate the nozzle over the second pour-over setup in replacement of the first pour-over setup;
• and
• dispense heated water into the second pour-over setup according to the second target dispense pattern.
