Gazebo Newsletter 15 May 2019

Following quickly on the heels of the Ignition Acropolis release in February 2019 comes Ignition Blueprint. This release took place over the last couple weeks of May, and offers a few new features including:

  • Physically based rendering (PBR) materials.
  • GUI tools for model placement, and a new Scene Tree widget.
  • Air pressure and RGBD sensors.
  • Global wind model.
  • Joint state publisher.
  • Support for UAV vehicles.
  • Integration of `ign` command line tool into Ignition Gazebo.
  • Command line tools for logging.
  • Battery model based on vehicle payload and motion.
  • Integration of Google benchmark for performance metrics and analysis.

PBR allows simulation models to gain a marked visual improvement. This will benenfit both human observers, and image-based sensors. Mouse over the following image to see the difference between a scene lacking PBR and a scene with PBR.

Community Contributions

We'd like to highlight a particular contribution that began back in February of 2017. Martin Pecka created pull request #2652, which added support for tracked vehicles in Gazebo. Take a look at the video below for a short demonstration.

Another long standing pull request that has been recently merged is pull request #2058, created by Carlos Miguel Correia da Costa back in December of 2015, which added support for camera intrinsics parameters in Gazebo.

Featured Model

A model of the Edgar Experimental Mine has been created for use in the SubT Challenge. This model will also be useful to anyone interested in underground robotic applications.

Ignition Acropolis Release

We are proud to announce of release Ignition Acropolis. Please read the complete post about the release here

Future of Gazebo

The latest release of Gazebo, Gazebo 10, was rolled out in January 2019. We plan to continue to support Gazebo over the coming year and release Gazebo 11 in 2020. Gazebo 11 will be an LTS release, with a EOL date of Jan 2025. Gazebo 11 will also the be final release of the Gazebo lineage. Development efforts toward simulation will focus primarily on Ignition. Users of Gazebo can expect migration guides, tutorials, and additional help to be developed over the course of 2019 and 2020 to aid in the transition.

Over 16 years of experience has helped to inform and guide the development of Ignition. We believe that the shift toward Ignition will be extremely beneficial to community. As always, this remains an open-source project and we look forward to your feedback and contributions.

Gazebo Newsletter 14 November 2018

Libraries within the Ignition Robotics framework have been under development for a few years now. For example, Ignition Transport was started back in 2014. Ignition Robotics is now ready for a unified release, which would consist of a curated and compatible group of library versions. This first major release of Ignition Robotics will arrive in February 2019.

An alphabetic naming scheme has been chosen for Ignition Robotics in preparation for the release. The naming scheme will be used to guide the creation of release names, similar to Ubuntu and ROS. One difference is that Ignition will use only a noun to name a release, instead of a adjective-noun pair. The naming scheme is architecture, and the first release of Ignition Robotics will be named Acropolis. More information about Ignition Acropolis will be available leading up to the release.

Featured Models

A generic quadcopter and hexacopter are available for use in simulation. These models are used in SubT, and can be controlled the using the RotorS package.

The DARPA Subterranean Challenge has officially kicked off. You can find out more information, including how to register, at subtchallenge.com. Over the next few years Open Robotics will be supporting this challenge and significantly improving simulation along the way.

The improvements to simulation are taking place in the Ignition Robotics project. We have our first major release of the project in February 2019. This release is set to include our new plugin-based physics and rendering systems, an updated graphical user interface based on Material Design, and support for distributed simulation. The goal of Ignition Robotics is to improve the usability, scalability, and flexibility of Gazebo while maintaining or improving Gazebo's current level of simulation fidelity.

Given the resources of Open Robotics, we have to make trade-offs in our development and maintenance efforts. Gazebo10, to be released in January 2019, will be the last major version of Gazebo based on the code in bitbucket.org/osrf/gazebo. A new version of Gazebo, based on the Ignition libraries, will be part of the Ignition Robotics release in February 2019. We will continue to support older versions of Gazebo including versions 7-10 through their planned EOL dates which reach out to 2023 for Gazebo9.

Gazebo Newsletter 12 August 2018

This month we have three updates on upcoming features in Ignition Robotics. The first is a new library for registering plugins and dynamically loading them at runtime. This library is called Ignition Plugin and can be found at https://bitbucket.org/ignitionrobotics/ign-plugin. A few features offered by Ignition Plugin include:

  • Users can register template-based classes as plugins and/or interfaces.
  • Plugin libraries that are no longer in use will be automatically unloaded.
  • A plugin can be registered anywhere from within any translation unit.
  • Interfaces never need to be queried by name with a string.

Ignition Transport has acquired topic remapping, which will be distributed in version 5. Topic remapping allows a user to programmatically reassign a topic's name to a different name. Remapping can be useful when playing back log files, or interfacing to another piece of software that requires a specific topic name.

Lastly, we are making progress toward Ogre2.1 support in Ignition Rendering. Support for Ogre2.1 will arrive in late September, alongside a beta release of Gazebo11. Ogre2.1 offers improved performance, material handling, and rendering fidelity.
