Mar 1, 2025

March 2025 — Safety-first, reliability-focused platform improvements across the reefing system. Delivered end-to-end features that enhance operator visibility, measurement fidelity, motion control precision, autonomous reef handling safety, and vision robustness. Key outcomes include safer climber operations with real-time feedback and LED indicators, non-blocking algae measurements coordinated with shooter logic, smooth trapezoidal-motion profiles for wrist and intake with safety interlocks, safer autonomous reef handling with improved release tolerances, and calibrated vision parameters with consistent angle math for robust localization and control. These efforts reduce risk, improve mission uptime, and increase confidence in automated reef interactions.

Feb 1, 2025

February 2025 — thedropbears/pyreefscape delivered significant reliability and maintainability gains across code quality, perception, and control. Key features delivered include code quality tooling with Ruff and mypy; LED patterns and lighting improvements via WPILib with status indicators; vision system enhancements including tag-not-seen indicators and removal of alt pose; architectural refactor splitting the manipulator into shooter and injector; and distance-based calculations using distance function and transform3d sum. Major bugs fixed include removing a circular reference in physics.py; limiting velocity mode to measurement phases; fixing mypy warnings from variable reuse; not modifying heading PID values; ensuring correct rotation handling; and iterating over all groups. Overall, these changes reduce runtime errors, improve safety, and accelerate debugging and tuning. Technologies demonstrated: static analysis tooling (Ruff, mypy), WPILib LED and vision APIs, transform3d, distance-based estimation, PID control, IMU-based heading strategies, and modular architecture with tunables.
