Migrating Gazebo plugins to ROS2

Google Summer of Code 2019

Project: Migrating Gazebo Plugins to ROS2
Organization: Open Source Robotics Foundation
Mentor: Louise Poubel
Student: Shivesh Khaitan (

Working for Open Source Robotics Foundation as a Google Summer of Code 2019 Student Developer was a wonderful learning experience. I would like to thank my mentor @chapulina for guiding me throughout the course of the project.

Project Overview

The project aimed to migrate the existing gazebo_ros_pkgs in ROS1 to ROS2 with proper documentation, testing and demos. Gazebo ROS packages include ROS packages which provide a ROS interface to Gazebo simulations, so developers can test their ROS code in a virtual simulation instead of a physical robot.

What has been done?

The migration is complete and most of the work has been merged and even released. The work targeted ROS2 distro Dashing Diademata. All of the plugins (apart from those deprecated) have been migrated.

I. Gazebo Plugins

Gazebo Plugins package provides plugins for common mechanical drives, sensors and other utilities to be used in Gazebo for to ease interfacing with ROS. Following is a list of the contributions to the package:

Apart from the migration, some new functionalities were also added to ROS2.

I. gazebo_ros_ackermann_drive
An additional plugin for car-like robots. #945
Status: :white_check_mark: merged

II. CUDA accelerated Depth Camera
GPU accelerated computationally expensive processes of depth_camera_plugin for better performance. #981
Status: :hourglass: under discussion

II. Gazebo ROS

Gazebo ROS package provides implementation of Gazebo Node, Executor, common conversion utilities, World and System Gazebo plugins. Following is a list of the contributions to the package:

Additional Work

Apart from the planned migration of gazebo_ros_pkgs, some work has been done on a new package ros2_ign which provides integration between ROS2 and the new ignition-gazebo. Following is a list of the contributions to it:

static_bridge ros2_ign_bridge #1 :hourglass: under discussion
parameter_bridge ros2_ign_bridge #3 :hourglass: under discussion

Future Plans

Though the planned milestones have been achieved, I would like to continue to contribute to OSRF in the future. As the packages have been recently released, I am waiting for the feedback from the users on the work and would like to address any bugs or reviews on it.

Important Links

Again I would like to thank OSRF and my mentor @chapulina for providing me this wonderful opportunity. Thank you for reading.

Great work Shivesh! Glad to see those continued to be maintained (I had a very similar OSRF internship many years ago)
