Emma Kadlecek developed advanced autonomous navigation and control features for the gwhs/2025-Reefscape robotics repository, focusing on reliable path planning, subsystem integration, and operator feedback. She implemented velocity-based closed-loop control for swerve drive, refined PID-based pose alignment, and introduced robust hardware health monitoring. Using Java and Gradle, Emma enhanced code organization, simulation safety, and real-time diagnostics through LED indicators and battery monitoring. Her work included modular subsystems for end effectors and ground intake, as well as parameterized tuning for smoother autonomous alignment. The engineering demonstrated depth in robotics software, embedded systems, and maintainable code practices, improving both reliability and testability.

Sep 1, 2025September 2025 — Key feature delivered: Autonomous Alignment Stability Tuning for gwhs/2025-Reefscape. Reduced aggressiveness factor from 0.4 to 0.3 to make autonomous alignment less abrupt and more controlled, improving target position prediction during autonomous routines. No major bugs fixed this month based on available data; focus was on feature delivery and stability improvements. Impact: smoother autonomous alignment enhances reliability, safety, and mission success rate while reducing wear on actuators. Technologies/skills demonstrated include robotics control tuning, parameterization, Git-based version control, and collaboration within the Reefscape project.
