This repository contains the robot description and necessary launch files to simulate the Light Autonomous Underwater Vehicle (LAUV), developed by the Laboratório de Sistemas e Tecnologia Subaquática (LSTS) from Porto University and OceanScan-MST. This repository is complementary to the Unmanned Underwater Vehicle Simulator (UUV Simulator), an open-source project extending the simulation capabilities of the robotics simulator Gazebo to underwater vehicles and environments. For installation and usage instructions, please refer to the documentation pages. The information about the vehicle dynamic model and physical dimensions were retrieved from the following sources:

• Sousa, Alexandre, et al. "LAUV: The man-portable autonomous underwater vehicle." IFAC Proceedings Volumes 45.5 (2012): 268-274.
• da Silva, Jorge Estrela, et al. "Modeling and simulation of the LAUV autonomous underwater vehicle." 13^th IEEE IFAC International Conference on Methods and Models in Automation and Robotics. Szczecin, Poland Szczecin, Poland, 2007.

Purpose of the project

This software is a research prototype, originally developed for the EU ECSEL Project 662107 SWARMs.

The software is not ready for production use. However, the license conditions of the applicable Open Source licenses allow you to adapt the software to your needs. Before using it in a safety relevant setting, make sure that the software fulfills your requirements and adjust it according to any applicable safety standards (e.g. ISO 26262).

Requirements

To simulate the Light Autonomous Underwater Vehicle (LAUV), please refer to the UUV Simulator repository and follow the installation instructions of the package. Then you can clone this package in the src folder of you catkin workspace

cd ~/catkin_ws/src
git clone https://github.com/uuvsimulator/lauv_gazebo.git

and then build your catkin workspace

cd ~/catkin_ws
catkin_make # or <catkin build>, if you are using catkin_tools

Configuration of the Gazebo world

The simulation with the fin plugins have shown better results by configuring the Gazebo's .world file with the following parameters for the physics engine:

<physics name="default_physics" default="true" type="ode">
  <max_step_size>0.01</max_step_size>
  <real_time_factor>1</real_time_factor>
  <real_time_update_rate>100</real_time_update_rate>
  <ode>
    <solver>
      <type>quick</type>
      <iters>50</iters>
      <sor>1.2</sor>
    </solver>
  </ode>
</physics>
