Overview of ANSASV Project

We are in the process of developing ANSASV - an open-source, modular autonomous navigation framework for surface vehicles, with a focus on autonomous waypoint navigation, dynamic obstacle avoidance, and real-time awareness of environmental conditions (e.g., shoreline detection, water depth, and obstacles). Our goal is to provide a flexible solution that can be adapted for various marine applications such as patrolling, lake/ocean cleaning, bathymetric surveying, and sample collection. The project is based on ROS2, and we aim to integrate real-time sensors like LIDAR, GPS, IMU, and depth sensors.
