Feb 1, 2025February 2025: PurdueLunabotics/purdue_lunabotics — Focused on stabilizing robot navigation through a state-machine refactor. The work reorganized point-to-point navigation into a state-driven flow with explicit movement and target acquisition states, added error calculations, and clarified transitions to improve modularity and maintainability. The refactor exposed instability in the navigation loop, and the system is currently broken and requires stabilization, tests, and a clear rollback strategy. Documented findings and a broader plan for next steps.

Jan 1, 2025January 2025 highlights for PurdueLunabotics/purdue_lunabotics. Focused on improving autonomy and reliability of the point-to-point navigation system. Key feature delivered: robust point-to-point navigation with a new navigation script, PID controller enhancements, configurable limits and tolerances, improved pose/velocity estimation, visualization markers, enhanced path handling, and path simplification to deliver more reliable user-facing autonomous navigation. Work also included simulation validation and deployment-readiness improvements (robot.launch updates). Major bugs fixed: fixed a critical bug causing robot teleportation during navigation and stabilized point-to-point operation for dummy targets; ongoing integration work with D* path planning. Technologies/skills demonstrated: ROS-based navigation stack, PID tuning, scripting, visualization, path planning, simulation, and ROS launch workflow. Overall impact: increased reliability and safety of autonomous navigation, enabling safer missions with less operator intervention; lays groundwork for advanced path planning and scalable autonomy. Business value: higher mission success rate, reduced downtime, improved operator confidence.
