LOTUSim is an opensource multi-agent simulator for maritime operations, built by Naval Group to support marine research, development, and cooperation. It simulates aerial, surface, and underwater domains in an open-sea environment. LOTUSim is still growing with more features being released regularly.

LOTUSim is built around 3 core pillars: modularity, flexibility, and scalability. You can customize almost every component, run only what your scenario needs, and spread computing load across multiple machines. This is powered by communication protocols such as ROS2 DDS and WebSocket.
