This repository contains the robot description and necessary launch files to simulate the ECA A9 autonomous underwater vehicle. 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.

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 ECA A9 AUV, 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/eca_a9.git

and then build your catkin workspace

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

Example of usage

To run a demonstration with the vehicle with teleoperation, you can run a UUV simulator Gazebo scenario, such as

roslaunch uuv_gazebo_worlds ocean_waves.launch

and then

roslaunch eca_a9_gazebo start_demo_teleop.launch joy_id:=0

The teleoperation nodes are pre-configured per default for the XBox 360 controller.

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>

Check the Mangalia world file to see an example.

Contributing

Want to contribute? Great! You can do so through the standard GitHub pull request model. For large contributions we do encourage you to file a ticket in the GitHub issues tracking system prior to any code development to coordinate with the UUV Simulator development team early in the process. Coordinating up front helps to avoid frustration later on.

With the sign-off in a commit message you certify that you authored the patch or otherwise have the right to submit it under an open source license. The procedure is simple: To certify above UUV Simulator Developer’s Certificate of Origin 1.0 for your contribution just append a line

Signed-off-by: Random J Developer <random@developer.example.org>

to every commit message using your real name or your pseudonym and a valid email address.

If you have set your user.name and user.email git configs you can automatically sign the commit by running the git-commit command with the -s option. There may be multiple sign-offs if more than one developer was involved in authoring the contribution.

For a more detailed description of this procedure, please see SubmittingPatches which was extracted from the Linux kernel project, and which is stored in an external repository.

Individual vs. Corporate Contributors

Often employers or academic institution have ownership over code that is written in certain circumstances, so please do due diligence to ensure that you have the right to submit the code.

If you are a developer who is authorized to contribute to UUV Simulator on behalf of your employer, then please use your corporate email address in the Signed-off-by tag. Otherwise please use a personal email address.

Maintain Copyright holder / Contributor list

Each contributor is responsible for identifying themselves in the NOTICE file, the project’s list of copyright holders and authors. Please add the respective information corresponding to the Signed-off-by tag as part of your first pull request.

If you are a developer who is authorized to contribute to UUV Simulator on behalf of your employer, then add your company / organization to the list of copyright holders in the NOTICE file. As author of a corporate contribution you can also add your name and corporate email address as in the Signed-off-by tag.

If your contribution is covered by this project’s DCO’s clause “(c) The contribution was provided directly to me by some other person who certified (a) or (b) and I have not modified it”, please add the appropriate copyright holder(s) to the NOTICE file as part of your contribution.
