PROFILE

Alanyuan99

Alan Yuan developed modular robotic subsystems for Team488/TeamXbot2025, focusing on autonomous reliability, operator safety, and precise control. He engineered features such as angle-based arm control, PID-driven calibration routines, and subsystem readiness scaffolding, using Java and embedded systems techniques. His work included integrating sensor feedback, implementing safety safeguards, and refining command-based programming patterns to support both autonomous and manual operation. Alan enhanced operator interfaces with hardware button mappings and improved state management for lighting and camera alignment. By addressing edge cases and reducing startup risk, he delivered robust, maintainable solutions that improved system reliability and streamlined testing and maintenance workflows.

March 2025 monthly summary for Team488/TeamXbot2025: The team delivered key feature updates and stability improvements that enhance autonomous reliability, operator control, and system safety. Feature highlights include algae arm control enhancements with vertical repositioning and autonomous calibration to improve reliability during init; enhanced lighting and camera alignment feedback with new alignment states and refined lighting to reflect coral station alignment; elevator control improvements via NeoTrellis-based trim controls and manual gravity compensation for smoother operation. A bug fix removed the default CoralScorerSubsystem command to prevent unintended behavior on initialization. Impact: increased precision, repeatability, and ease of operation in both autonomous and manual modes; reduced startup risk and maintenance overhead. Technologies demonstrated: motion/control state machines, hardware button mappings, gravity compensation, and lighting/camera state management.
