Added telemetry system demo program - Loads flight data from CSV into doubly linked list - Simulates drone flight with motor control - Demonstrates forward/backward list traversal - Calculates and displays flight statistics
Add flight data generator script - Generates 50 simulated GPS waypoints - Creates realistic flight profile (takeoff, cruise, landing) - Includes GPS, IMU, velocity, battery, and signal data - Outputs to DroneFlightLog.csv for testing
Dynamic Hazard Detection System with O(1) lookup Implements real-time dynamic hazard detection using hash maps for optimal performance in drone pathfinding applications. Features: - O(1) average-time hazard lookup using unordered_map with integer keys - Time-based automatic expiration of temporary hazards - Multiple hazard types: BIRD, DRONE, WEATHER, DEBRIS, AIRCRAFT - Severity levels (1-5 scale) for risk assessment - Path safety verification for complete route checking - Python-based hazard data generator for testing scenarios - File I/O for persistent hazard logging and reload capability Testing: - Includes comprehensive demo with 10,000 O(1) lookup test - Three scenario generators: light (5), medium (15), heavy (30) hazards - Path safety testing with sample routes - Time-based expiration simulation This feature completes the D-2 requirement for the CS221 drone route planning project, demonstrating efficient dynamic obstacle detection suitable for real-time navigation system
