Simple (and currently incomplete) Python wrapper around the Opentrons HTTP API. Like https://github.com/Opentrons/opentrons/tree/edge/api-client, but in Python. This API is atomic and interactive.
This project is created for use with PyLabRobot, but can be used however you like.
- from pip
pip install opentrons-http-api-client- from source
git clone http://github.com/rickwierenga/opentrons-python-api
Minimal example for simple liquid handling:
import ot_api
ot_api.set_host("x.x.x.x") # find in OT app
ot_api.set_port(31950) # default, so not really necessary
# Creating a run
run_id = ot_api.runs.create()
ot_api.set_run(run_id) # set run globally, alternative to `run_id` parameter for functions
# Add pipettes that are detected in hardware to the software
left_pipette, right_pipette = ot_api.lh.add_mounted_pipettes()
left_pipette_id = left_pipette["pipetteId"]
# Defining labware
labware_def = ot_api.labware.define(labware_definition) # json from opentrons-shared-data
# Adding labware
labware_id = ot_api.labware.add(labware_def, slot=1)
# Picking up a tip
ot_api.lh.pick_up_tip(labware_id=labware_id, well_name="A1", pipette_id=left_pipette_id)
# Aspirating
ot_api.lh.aspirate(labware_id=labware_id, well_name="A1", pipette_id=left_pipette_id,
flow_rate=10, volume=10)
# Dispensing
ot_api.lh.dispense(labware_id=labware_id, well_name="A1", pipette_id=left_pipette_id,
flow_rate=10, volume=10)
# Tip drop
ot_api.lh.drop_tip(labware_id=labware_id, well_name="A1", pipette_id=left_pipette_id)Note: the ot_api is blocking!
