You can even load a Tesla simulation with Webots, in which you have a Tesla in a city: ros2 launch webots_ros2_turtlebot robot_launch. You can list the ros2 topics just as you did for the previous simulation: ros2 topic list Simulator integration: ROS also has ties to open source simulators such as Gazebo and has a good interface with proprietary simulators such as Webots and. When we compare Gazebo with other simulators such as V-REP and Webots, they have inbuilt functionalities. But after a while, you should have the Turtlebot simulation up and running: Complete simulation is done only through coding in ROS. The reference attribute should match the Webots device name parameter. These plugins can be loaded using the tag in the URDF file of the robot.It may take a while to load because Webots downloads the assets in the background. As mentioned in Setting up a robot simulation (Basic), webotsros2driver contains plugins to interface most of Webots devices with ROS 2 directly. For External Controllers, the documentation is available at Īnother simulation you could launch with Webots is Turtlebot: ros2 launch webots_ros2_turtlebot robot_launch.py This feature is already available on Humble and Rolling and will step into Foxy and Galatic at the next sync. In any case, you can always refer to the official documentation. Dear ROS community, The webotsros2 package is now compatible with Windows Subsystem for Linux (WSL) to improve the experience of Windows users who use ROS2 with Webots. If you want to move a robot, you would need external controllers, but that is a topic for another post. You can now go to a second terminal and check the topics with: ros2 topic list That command will basically load the world that we saw in the previous picture. Letâs launch a simulation using the following command: ros2 launch webots_ros2_epuck robot_launch.py That workspace contains ROS2 packages ready for Webots. Launching a Webots worldĪs you may have noticed, we have a workspace named ros2_ws. Therefore, only the C API can now be used in plugins. Under-the-hood: Cyberbotics uses a CI based on Ubuntu 18.04 to build the Debian package. As of Webots R2021c (or R2022a), ROS Noetic will work with the Debian package (but ROS Melodic will not). ROS Melodic works with the Debian package and the Ubuntu 18.04 tarball. This is due to the fact that the webotsros2driver package (which defines the WebotsNode) doesn't use the C++ API of the libController anymore. ROS Noetic works with the Ubuntu 20.04 tarball. Ok, now that you know how to open Webots manually, feel free to close the simulator by pressing CTRL+C on the command line, or manually pressing the Close Webots button available on the top right corner of the simulator. However, when I run a launch file that prompts to open Webots, it cannot recognize the Windows installed Webots, and search for Webots in the WSL2 system and cannot find it. Since version 2023.0.0 of the webotsros2 package, the Robot node (or Supervisor or Driver) cannot be accessed anymore.
