4 Commits • 1 Features
Aug 1, 2025August 2025 (Opentrons/opentrons) focused on reliability, safety, and predictable automation workflows. Key features delivered include the addition of deck conflict checking for the Flex Stacker to prevent incorrect labware placement, and stability improvements for the pipette detach flow by updating position estimation to include the rightZ and leftZ axes to avoid false stall detections. Major bug fixes address critical error recovery and state handling: refactoring StackerHopperLwInfo to use a static title in error recovery and ensuring proper recovery queue state transitions when the door is open or the queue is paused, accompanied by a new test for the door-open scenario, and ensuring engine recovery state correctly respects door status. Overall, these changes increase automation reliability, reduce troubleshooting time, and improve safety during deck operations, detach sequences, and error recovery. Technologies and skills demonstrated include refactoring for UI/state reliability, test-driven development with targeted door-open scenario tests, axis-aware position estimation, and robust error recovery and deck placement validation.
