This is an intelligent underwater robotic platform for real-time exploration, data collection, and 3D mapping of marine environments. Equipped with advanced sensors like DVL, IMU, SONAR, and LiDAR, it uses Unscented Kalman Filter-based sensor fusion for accurate navigation in GPS-denied waters. The system autonomously manages path planning, obstacle avoidance, and adaptive mapping, while enabling real-time monitoring and post-mission analysis.
