Albert Yang Sun developed core autonomy and navigation features for the CUSail-Navigation/sailbot repository, focusing on hardware-software integration and wind-aware sailing control. He implemented a Teensy-based serial servo driver with ROS2 integration, enabling real-time sail and tail servo actuation, and introduced tacking logic that accounts for wind direction and nogo zones. Using C++, Python, and ROS, Albert automated environment setup and deployment, streamlined remote debugging, and improved build reliability through configuration management. He also addressed cross-module data integrity, refining wind angle and IMU data handling. His work demonstrated depth in embedded systems, sensor integration, and robust system configuration.

Nov 1, 2024In 2024-11, delivered core autonomy enhancements for CUSail-Navigation/sailbot, focusing on hardware-software integration and wind-aware sailing control. Implemented a Teensy-based serial servo driver with ROS2 integration to enable real-time sail and tail servo control, along with a ROS2 node subscribing to rudder and sail commands. Also added a Sailboat Tacking Functionality to the main control algorithm, with wind-direction-based tack initiation, tacking point calculations, and tacking state management. These capabilities advance onboard autonomy, improve control reliability, and lay groundwork for automated, wind-aware sailing maneuvers.
