Jun 1, 2025June 2025 performance summary for itu-auv/auv-software: Delivered substantial improvements to autonomous alignment and sensor integration. Key features include Align Frame Controller (AFC) enhancements such as safer cancellation via a zero-velocity command, improved processing reliability after cancellation, and a new keep_orientation mode to preserve the vehicle's orientation during alignment. IMU Odometry now timestamps using the incoming IMU timestamp, improving synchronization and localization accuracy, with delta logging to aid debugging. Logging verbosity for object_map_tf_server_ros was tightened by downgrading general informational logs to DEBUG, reducing noise during normal operation. Notable bug fixes include a sleep after zeroing Twist to ensure timing correctness and addressing log spamming in object_map_tf_server_ros.cpp. These changes improve control robustness, observability, and overall system reliability, delivering measurable business value in safer autonomous operation and faster issue diagnosis.
