Autonomous maritime systems are inherently interdisciplinary, so one of the primary challenges that engineering teams face is the need to plan, communicate, and integrate the different aspects of their designs. In this talk, we will demonstrate how MATLAB and Simulink can help provide a unified environment for the development and simulation of autonomous surface vessels (ASV). The webinar will be centered around a reference application that simulates an ASV navigating from one dock to another in a canal. We will discuss how MathWorks tools are used to create different modules in this reference application, including scenario simulations, vehicle models and hydrodynamics, autonomy stack, and user interfaces. We will highlight how the physics-based simulation in Simulink can be connected to photorealistic simulators such as Unity® to create a powerful framework for testing and validation of ASVs. We will also show how you can connect your existing work to Simulink and leverage the power of this simulation framework.
