Oct 1, 2025October 2025 monthly summary for MRoboSub/mrobosub focusing on business value and technical impact. Delivered ROS2 modernization and project cleanup across the MRoboSub stack, removing legacy ROS1 dependencies and reorganizing configuration/files to enable a cleaner, more maintainable ROS2 environment. Implemented internal refactor to support Quartermaster, and fixed critical HAL path resolution issues to improve launch reliability. Updated library versions (mrobosub_lib to 2.0.0) and extracted/parameterized mrobosub_planning params for better configurability. Enhanced operator tooling by introducing console scripts for DVL, botcam, and Zed in mrobosub_hal to improve runtime usability and accessibility for daily operations. These changes collectively reduce maintenance overhead, improve deployment stability, and accelerate downstream feature delivery.
