Mar 1, 2026

March 2026 monthly summary for rsx-rover focused on streamlining autonomy deployment and improving reliability of the rover autonomy stack. Delivered Rover Autonomy Deployment Improvements by removing the heartbeat publisher script and related launch configurations to reduce startup fragility and maintenance overhead. Integrated rtabmap_init.py into the installation process to ensure consistent autonomic feature deployment and easier onboarding of localization-related functionality. Minor build/config adjustments accompany the changes (thoroughly documented in commits).

April 2025 monthly summary for rsx-rover: Key feature delivered: Enhanced Pathfinding Algorithm with Cartesian Distance and Visited-Location Tracking. This feature introduces Cartesian distance calculation, excludes already visited locations in weight calculations, fixes initialization of the locName list and remaining locations dictionary, and adds a sample execution block for testing. Major bugs fixed: fixes in path planning stability tied to optimal_path (commit 201a7a40c0393efbcb24943ab3c99961de3bb9fc). Overall impact: improved route planning accuracy, reduced redundant visits, and more reliable autonomous navigation; testing scaffolding accelerates verification of path planning scenarios. Technologies/skills demonstrated: Python data structures (lists and dictionaries), pathfinding algorithm design, code instrumentation, and incremental refactoring with test-oriented development.
