This project is based on my Masters Degree in Computer and Automation Engineering (Marche Polytechnic University) Final Thesis. I started the project during my Erasmus internship in Ireland at the University of Limerick, in particular at the CRIS (Center for Robotics & Intelligent Systems) department, an Irish research center that deals with the application and development of marine robotics.
The Project consists in the study and implementation of a Navigation, Guidance and Control System for a biomimetic Robot, focusing on the implementation of a simulation environment using Matlab Simulink, enhanced with a 3D graphic interface (Virtual Reality World).
The simulator deals with:
- Mathematical Model (Kinematics and Dynamics)
- Propulsion System
- NGC System:
- Line of Sight (LOS) Guidance Law
- Path following Control System (using PID)

Note:
- Since I only dealt with the simulation environment, the vehicle's states are derived derictly from the robotic-fish mathematical model.
- The vehicle is assumed to be in an environment without any kind of disturbances and without any noises in position and attitude measurements.
The propulsion system of the prototype is composed of a total of six actuators (overactuated), of which three are traditional propellers and the other three are bio-inspired propellers, namely the caudal fin and the pectoral fins.
Waypoint-based path, consisting of a total of four waypoints.
