Developed direct throttle control for fixed-wing aircraft within the Auterion/px4-ros2-interface-lib repository, focusing on enhancing control fidelity and expanding integration with ROS 2. The work involved adding a throttle_direct field to the FwLateralLongitudinalSetpoint structure and publishing this setpoint in the lateral_longitudinal.cpp update path, enabling precise throttle management through ROS 2 pub-sub mechanisms. Leveraged C++, embedded systems expertise, and git-based workflows to deliver this feature, which unlocks new use cases for fixed-wing robotics applications. No major bugs were addressed during this period, with efforts concentrated on implementing and integrating the new throttle control capability into the existing codebase.
