If you are familiar with pubsub, or tools like MQTT you probably understand how messaging systems work. Step 5: Run roscore in the docker container The last line refers to the melodic version of ROS.

Sudo apt-get install ros-melodic-ros-tutorials Within the container run the following to update packages and install the ROS tutorials: sudo apt-get update The DISPLAY environment variable creates a pointer to send display commands to Xquartz. This will now put you inside the ROS docker container where you can run commands. In the same terminal window, run the following commandĭocker run -e DISPLAY=:0 -it -name my-ros ros.This will pull the latest ROS docker image down to your local machine. Open up a second terminal (with terminal in focus, press: Command-T).Instead of struggling to get ROS running on your Mac, you can just use an official docker container image (ros). If you press Command-Tab you will see that Xquartz was launched by the xhost command. You should see a response like this: 127.0.0.1 being added to access control list The docker images run headless, which means you need to setup Xquartz running on your Mac to display the simulation. From the main menu select: Xquartz > Quit X11.Check Allow connections from network clients.Click the Security tab in the dialog box.In the main menu select: Xquartz > Preferences.On the main menu select: Go > Applications.Click a blank area on your Mac desktop which will make Finder the focus of the main menu.Once Xquartz is installed you need to run it and set a security preference: Note that it may take a moment and that the installer window might end up behind another window.Double click the *.pkg file to run the installer.Open the *.dmg file and you should see the Xquartz.pkg file.Download the *.dmg file for your operating system.To install Xquartz for a Mac, go to this link and download the *.dmg file: If not, follow the install instructions from this link: If you've already installed Docker for Mac, move to the next step.

Then you can go back and better appreciate what the tutorials are trying to accomplish.

To simplify the process, I'm going to use Docker and Xquartz to show you how to get a visual simulation working. But I've noticed hobbyists get frustrated with the lengthy setup process. In this article I show an absolute beginner to ROS (Robot Operating System) how to run a TurtleSim (turtle robot simulation) as quickly as possible on a Mac.
