Can info collection be delegated to python if the file matches some pattern in which the script is more declarative than imperative? So let's do that. Love podcasts or audiobooks? As you can see, we also use a set of config files to setup the user. Will this work if I have one workspace that I built with catkin_make and the other one (the ~/ROS/ one) with catkin build? Order of catkin source setup.bash files matters? Go ahead and try to put a package in the source folder. This involves multiple scripts (about 5) per colcon package. install\setup.bat One Time Setup I got the following error: E: Unable to locate package ros-galactic-nav2-bringup and if I try to install it from source, i got build errors:. profiling.log. I attempted to use this method with "build" and "make" to no avail. Now let's create the workspace: The next lines will initialize the workspace and they will be different whether you are using ROS1 or ROS2. This can be dangerous though, and I highly recommend you do proper workspace chaining. I am just running through the ROS tutorials for Indigo (running on Ubuntu 14.04). Please see #764 which explicitly enumerated the goals and also references some work in progress to address this problem. Looking at the files under the extracted ros directory, there seems to exist a local_setup.ps1 file, which I suspect should be used to setup the workspace in Powershell (as also indicated here ). cd ~/ros2_ws colcon build --symlink-install --packages-select server source install/setup.bash ros2 run server server We can check if the service is running by using the ros2 service command. For applications that needs to have access to the X server you need some extra commands. from the postprocessing script in ros2 Debian packages. In ROS2, debians conflict with packages built from source. So unless something new is installed from .deb packages in "/opt/ros_", setup.bash would be static and instantaneously executable. ros2 is not found, meaning the binaries workspace was not recursively sourced when sourcing the workspace install setup.bash bash: ros2: command not found Additional information When sourcing the binary workspace /opt/ros/crystal/setup.bash beforehand (manually) followed by sourcing the workspace it works fine. For other platforms than Linux, rosbag2 has to be built from source as it's currently not part of the latest ros2.repos file. Open a new tab inside an existing terminal use the shortcut ctrl+shift . as long as the setup scripts take several seconds even for small workspaces (two packages, each includes only one library/executable) on relatively fast systems (recent Core i5, Samsung 850 Pro SSD). While the invocation is faster it simply doesn't set the environment variable it is supposed to. The node will be really minimal and simple. Therefore, as a temporary workaround I put everything in a script which I source: Of course, this is limited to a default installation, but maybe it's useful for someone as long as there is no better working solution. Form the name of the source files, I would assume that local_setup.bash is sourcing every package individually (as observed), but setup.bash should source the whole workspace at once. For example if two different workspaces have similar packages. Original to patch would be https://github.com/colcon/colcon-bash/blob/master/colcon_bash/shell/template/prefix.bash.em, but because of the caveat, I am hestiant to create a pull request. I just asked for the additional context to clarify that it is actually not the time for only two packages but numerous (likely hundreds) installed Dashing packages. That is typically been my experience too when developing. This is certainly not a common performance for such a setup. Is there a way to speed-up the sourcing process in ros2 Eloquent? Therefore the command to setup the workspace is call C:\dev\ros2_dashing\local_setup.bat. @dirk-thomas We are currently integrating colcon into the ROS Qt Creator plugin and also noticed the pause due to sourcing. You should clone recursively as it contains submodules. Directions Open up a new terminal window (I'm assuming you are using ROS on Ubuntu Linux ), and type the following commands to create and build at catkin workspace. However, they are dispersed in multiple repository on DockerHub and it is sometime confusing to understand which image you need. You create a specific folder and use catkin_make. Is there a way to speed-up the sourcing process in ros2 Eloquent? 1 Source ROS 2 environment . For example, is there a way to do the sourcing only once (e.g., at boot time), rather than repeating the process for all bashes? You should build two times to generate all the trajectories. dirk-thomas added enhancement and removed bug labels on Aug 20, 2019 Note that the required structure is a top-level directory and a src/. @clalancette thank you for the feedback. Any suggestion ? The first thing is to decide which base image to use: Now if you want to be a bit more generic you can use Docker ARG command: The first two lines are to set a default version, but we will see later how to pass the arguments when building the image. #!/bin/bash set -e # setup ros2 environment source "/opt/workspace/install/setup.bash" exec "$@" I could then create the docker image and run rviz inside it: docker build -t ubr:main We will use wstool for this. [*] Realized this phrase means nothing. AMENT_TRACE_SETUP_FILES=1 source /opt/ros/bouncy/setup.bash It provides the services you would expect from an operating system, including hardware abstraction, low-level device control, implementation of commonly-used functionality, message-passing between processes, and package management. Creating a workspace ROS 2 Documentation: Foxy documentation ROS 2 Documentation: Foxy Installation Ubuntu (Debian) Windows (binary) Alternatives Ubuntu (source) Ubuntu (binary) Windows (source) macOS (source) macOS (binary) Fedora (source) Latest development (source) Maintain source checkout Testing with pre-release binaries Sourcing the default ROS2 workspace via source /opt/ros/bouncy/setup.bash takes much longer than sourcing a ROS1 workspace. Source ros2. C:\dev\ros2_dashing\share/ament_index_cpp/local_setup.ps1, C:\dev\ros2_dashing\share/ament_cmake_core/local_setup.ps1, etc.) Using this docker pull ensures that you always have the latest version of the image. Always source the global ROS install before your catkin workspace. Let us start by creating a Dockerfile that will contain all the installation steps. This space should remain unchanged by configuring, building, or installing. You need to be careful to source devel/setup.bash for the correct workspace. Sourcing setup.bash on ROS2 takes considerably longer compared to ROS1. C:\dev\ros2_foxy\local_setup.ps1. It is quite common to have many "active" workspaces at a single time. The second part takes care creating a user with the same UID and GID as the host user. what episode does luffy get poisoned in impel down In the run command we also use the net=host argument to share the same network as the host machine. Commands are executed in a terminal: Open a new terminal use the shortcut ctrl+alt+t. The source space contains the source code of catkin packages. In your case, I'd do the following: In a new terminal run source ~/catkin_ws/devel/setup.bash cd into ~/ROS/ and run rm -r devel/ to remove the devel directory run catkin_make from the ~/ROS/ directory (this will re-create devel/) Then source ~/ROS/devel/setup.bash ros2-image-publisher / image_publisher_ros2_workspace / src / image_publisher / package.xml Go to file Go to file T; Go to line L; Copy path The instructions provided in the tutorial seem to be for a CMD. @Levi-Armstrong Sourcing the workspace generally does things like setup PYTHONPATH, LD_LIBRARY_PATH, and things of that nature. This can be useful, especially when you clone repositories in the container and you know that a new version of them is available. So, remove any existing MoveIt debians: sudo apt remove ros-$ROS_DISTRO-moveit* Create Workspace and Source Create a colcon workspace: export COLCON_WS=~/ws_moveit2/ mkdir -p $COLCON_WS/src cd $COLCON_WS/src Download Source Code Download the repository and install any dependencies. How does ROS know from which workspace it should run a launchfile? Or is there another solution to this? We will cover this in Part 2 of this tutorial. Complete ROS2 Course for Beginners: . Whats next? Learn how to create a ROS2 workspace, how to build your workspace, and how to source it so you can run your own nodes. We use two scripts here that you can copy paste and put in the config folder. It prevents bash to ask for user input, that would break the building process otherwise. I believe this is how virtualenv is separating environments too. and their dependencies. Learn how to create a ROS2 workspace, how to build your workspace, and how to source it so you can run your own nodes. Complete ROS2 Course for Beginners: https://rbcknd.com/ros2-for-beginners 0:00 Intro0:09 Create the workspace into your home directory1:26 Install colcon 2:18 Compile your ROS2 workspace with colcon2:42 Source your new ROS2 workspace3:42 Recap4:16 Outro Get my full-length courses https://rbcknd.com/all-courses FREE for 1 month! measure the time it takes to source the default workspace. Accessing data downloaded via catkin_download_test_data, Triggering pip requirements.txt from catkin build, Using a_pkg cmake extras in b_pkg cmake extras, (Groovy @ 12.04) Error on: $ ./src/catkin/bin/catkin_make_isolated --install, Creative Commons Attribution Share Alike 3.0. In the further tutorials, you will work in your workspace. A script to update setup.bash would be required and run e.g. Contribute to avizipi/ros2-image-publisher development by creating an account on GitHub. It works very well for me, when replacing the respective "local_setup.bash" of the system-installation and my workspaces sourcing is instantanous. zed-ros2-interaces contains the definitions of the custom topics and services, and the meshes for the 3D visualization of the camera models on Rviz2.It is very important to use the command --recursive while cloning the repository to retrive also the updated sub-module repository. ROS 2 nodes), data, libraries, images, documentation, etc. (e.g. Create another catkin workspace privacy statement. Specifically look for Building ROS 2 on Windows. For a workspace to be functional you might want to create a folder, shared between the host and the docker container. When I did both with "build" it worked like a charm. they can be installed in a separated or merged workspace. Contents 1 Installation Instructions So whatever you source in that command, it will disappear immediately. Have a question about this project? Don't run colcon build from a terminal where you've also sourced this workspace's setup file. :: change to the root of workspace pushd c:\nav2_ws :: build the workspace colcon build Activate the workspace which was built. First, we start with entrypoint.sh: And last but not least a script to modify the bashrc: Note that for ROS2, the last line should be changed to: We finish by a bit of cleaning and by calling the entrypoint: Now, to compile the image you will need to invoke the docker build command. The second column contains the accumulated time, the first one the time differences. Looking at the files under the extracted ros directory, there seems to exist a local_setup.ps1 file, which I suspect should be used to setup the workspace in Powershell (as also indicated here). You may also want to ensure that you cut out any excess cruft and isolate the execution, e.g. Cannot source workspace for Ros2 Dashing in Powershell, Creative Commons Attribution Share Alike 3.0. If you are unsure, we recommend you to simply use the full version. In another thread @dirk-thomas said that Eloquent has better performances (he said that sourcing ~300 pkgs takes about half a second) but still in my NVIDIA Jetson Nano with Ubuntu 18.04 and Eloquent, sourcing ~200 pkgs takes dozens of seconds. In both cases, they seem to source the source file of every package individually, e.g. source PATH/ros2_quick_setup.sh setup_ros2_environment /opt/ros/ dashing add_ros2_workspace /home/user/my_workspace Though this is still a workaround, having one common script to source arbitrary workspaces might be a good idea for further development. If you are here, it is to actually do something with those images. Please start posting anonymously - your entry will be published after you log in or create a new account. FYI I tend to try out solutions from GitHub blindly sometimes, so it's helpful if you have the time to vet it first! #include "rclcpp/rclcpp.hpp". In your ROS2 workspace, execute ros2 pkg create my_robot_bringup to init the package. Are you sourcing the local_setup file or setup? Note: The zed-ros2-wrapper repository contains the repository zed-ros2-interaces as a sub-module. To setup ROS 2 for use with PX4 you will need to: Install Fast DDS Install ROS2 Build ROS 2 Workspace Sanity Check the Installation (Optional) Install Fast DDS Follow the Fast DDS Installation Guide to install Fast RTPS (DDS) 2.0.0 (or later) and Fast-RTPS-Gen 1.0.4 (not later!) Lines beginning with $ indicates the syntax of these commands. !4980QTQtQt5/ C /c++// OpenCV /Quick/Qt22. Without this, Docker will simply use the cache and you will not pull the latest version of your repositories. Finally, the docker pull command is not necessarily needed as Docker will automatically download the latest version if not present on your computer. This tutorial explains how to use the Cartographer for mapping and localization. Build and Activate the Navigation 2 Workspace Build the workspace by colcon build tool. So the only solution I have come up with is to have all my packages in the same workspace. I just did a fresh install of Ubuntu 18.04 on a Ryzen machine with a fast PCIe SSD (native, not in a virtual machine) and dashing from the official repository. since this is closed, is there any related issue? Sign up for a free GitHub account to open an issue and contact its maintainers and the community. There's no single file that aggregates all environment hooks for all packages. In that case, you simply need to put it after the ${NAME}:${TAG}. Instead of recursively gathering environment variables from all shell scripts, wouldn't it be possible to cache these variables (as shown above) once a new package gets installed and only use a simple source script with this cache environment from there one? local_setup.bash sources the environment hooks for just one package or just one workspace (depending on where it was located. I have inspected the setup.bash files for both these workspace, and they are identical: @jarvisschultz's answer is correct, but you can also pass the --extend argument to the setup.bash file and it will only add to the environment rather than set the environment. Try these steps, Im going to do it now and see if it helped. Create a catkin Workspace. Slam Toolbox - How is scan data used to build the map? When you first run catkin_make in the root of a workspace, the devel directory gets created and the setup.bash file inside of that dir is designed to "overlay" the workspace on top of all other workspaces that have already been sourced. setup.bash will source environment hooks for the current package or workspace and it's dependencies. To build the ROS 2 workspace only: cd into px4_ros_com_ros2 dir and source the ROS 2 environment. PhD in Robotics and Human-Robot Interaction. Now let's see how we can actually use them and create our ROS workspace. By clicking Sign up for GitHub, you agree to our terms of service and Under step 2: rm -r build. Therefore the command to setup the workspace is call C:\dev\ros2_dashing\local_setup.bat. After you learned how to use Topics, . There is no hard rule about what to do, but some conventions make it . :: activate the workspace so that ROS can find your freshly built binaries. Well, it's about the total time a terminal needs to start if I put these things in, e.g., .bashrc. Start up times of 1.4 s (or ~3 s on the slower machine) just for sourcing /opt/ros/dashing/setup.bash can be quite annoying. While these hacks might work for your use cases locally they don't satisfy the requirement we have for the environment setup. Already on GitHub? We will explain about the contents of the package. other than the ones that come with ROS by default)? I then ignore the majority of packages, install dependencies and then build the workspace. Remember to monitor this and to clean the old version of your images: With all this you have a fully functional ROS workspace, with the ROS version of your choice, that you can deploy in minutes. Thanks to containerized solution like Docker you can create and deploy ROS workspaces in minutes. Follow. However, as long as the setup scripts take several seconds even for small workspaces (two packages, each includes only one library/executable) on relatively fast systems (recent Core i5, Samsung 850 Pro SSD), these hacks might be an option to setup the environment. In your case, I'd do the following: Your environment should now have the ~/ROS/ workspace overlayed on the ~/catkin_ws/ workspace. (COLCON_TRACE=1 source does not provide a list of source files for me.). This does bring up an issue of how to run multiple bots without redefining the params.yaml for each bot and running colcon build each time (as the C++ libs appear to be generated for the bt trees at this time). Thank you!Twitter: https://twitter.com/RoboticsBackend More Free Tutorials: https://roboticsbackend.com Without further ado let's dive into it. Now, to be useful we need to be able to add packages in there. . Sign in I will then add a button to the project build setting that when clicked will source the workspace and update the IDE environment for those who want to manually source the workspace when needed and they can turn off auto sourcing. The text was updated successfully, but these errors were encountered: I noticed the same behavior. : (copy-pasta'd bash-isolate from my gist, https://gist.github.com/EricCousineau-TRI/6870970d68f75d23061177a52932a5d1#file-bash_helper_functions-sh-L34 ). It is recommended to create a new overlay workspace on top of your current ROS 2 installation. And here you are, a fully compiled workspace for both ROS and ROS2. Random thoughts: If this is strongly coupled to decoupling [*], might there be a way to speed up composition? Workspace Colcon is a build tool for ROS 2. The problem is that if I now run echo $ROS_PACKAGE_PATH again, it gives me /home/karnivaurus/ROS/src:/opt/ros/indigo/share:/opt/ros/indigo/stacks. Build the packages using colcon and source the setup script of your workspace. Add a comment. However, my dashing installation on Ubuntu 18.04 from the official repository doesn't have an install folder and replacing local_setup.bash in /opt/ros/dashing caused an error on my fresh system (I think a python script was missing). That seems to indicate another problem which is probably slowing down the process. Then, follow the next points to see how to setup the package. But in the conversation you mentioned "several seconds even for two packages". Do you have any advice for reducing this sourcing time? Now, imagine having to deal with algorithms that run on a specific version of ROS or a robot that have been hooked on a computer that have not been updated for years by fear of it not working anymore. I seem to be having issues sourcing the workspace when using Powershell. adding an ampersand at the end of this line What you are suggesting isn't going to work. Try to put your launch file in a folder called launch that you'll create in the same folder in which you have src. The rest is similar and the images are used in the same way. A new colcon mixin for each known platform, which adds options to the colcon build task for using a sysroot generated with create-cc-sysroot, by using the same path conventions.For example, from a ROS 2 overlay workspace on a developer workstation, the following command would cross-compile the packages in the workspace up to a package performance_test for the platform specified. In ROS2 sourcing the default workspace takes a considerable amount of time (more than 2 seconds on my PC). Otherwise we would needed to troubleshoot why your performance was different (which at the end it isn't). Fund open source developers The ReadME Project. The proposed solution works on a Linux based host machine. 248 1 3 13. right now it is beside launch in the node folder, which is how it is stated in tutorials. Cofounder of AICA (www.aica.tech) who simplifies the way we program industrial robots and interact with them. Does anyone know how to go around this issue? Contribute to Interpause/ros- example - node development by creating an account on GitHub. We usually create a source folder that will be mounted at runtime. This error remains even after installing python-catkin-pkg with the command 1. Be aware that they do not include all the tools like rviz or gazebo you might need (those tools actually need some tricks to work in Docker, we will cover this in Part 2 of this tutorial series). I don't know what the real solution should be, but I sped up the sourcing a tad by adding an ampersand at the end of this line in install/local_setup.bash: _colcon_prefix_bash_source_script "$COLCON_CURRENT_PREFIX/share/${_colcon_package_name}/package.bash". Docker image for ROS2 armhf from source. I came across this thread looking for the same answer to this awful core problem. Instead I would like to run ROS2 in a Powershell window. I removed the "help wanted" label - not because we wouldn't like to get help on this but since it is a rather complicated issue to resolve and might not be a good issue to be found when users check to which tickets they could contribute To further understand the problem, I ran Don't mind if it tells you that a previous workspace was set before: cd ~/px4_ros_com_ros2 source /opt/ros/foxy/setup.bash Build the workspace: colcon build --symlink-install --event-handlers console_direct+ The official instructions for creating a ROS workspace are at ROS.org, but I will walk you through the process below so you can see how it is done. It is the place to create your packages and nodes or modify existing ones to fit your application. Note For example, if you need noetic, the latest version of ROS simply do: Here you are, you have downloaded a full working version of ROS noetic. I would suggest to first look into that / resolve that and then measure again. , but these don't seem to exists, even though the local_setup.bat equivalents are present. Luckily, official ROS images are released and regularly updated as soon as a new version comes in. ros-eloquent-ros-workspace version 0.8.0-1bionic.20191213.040754 is installed. Install webots_ros2 On macOS, a solution based on Docker containers allows to improve the user experience with ROS2 compared to native macOS installation, as it allows to run ROS on a Linux platform. But isn't that dangerous? The first time all env vars prefixed with ROS, or containing "/ros2_$ROS_DISTRO/" in their values are written to a unique cache file (in the user's home directory, if the directory containing local_setup.bash is not writable). Fabiobreo. ROS packages Now, if you want to have it directly built when building the image you need to add the following lines to your Dockerfile just before building the workspace: Note that every time you modify or add something in the source folder, Docker will notice the changes and will reinvoke the COPY command at build time, creating a new version of the image. Using python virtual environment for ROS2 on windows, Define custom messages in python package (ROS2). In order to build the core packages, you will need a catkin workspace. Hey I was having the same problem, although I noticed for Dashing that you require one more step than the Foxy version. Form the name of the source files, I would assume that local_setup.bash is sourcing every package individually (as observed), but setup.bash should source the whole workspace at once. answered Jul 30, 2016 at 8:14. For some years now, the Robot Operating System (ROS) has been widely use by academics and industrial alike to create their robotic tasks and standardize their developed algorithms. workspace ROS2 ROS2underlay source /opt/ros/<distro>/setup.bash dashing source /opt/ros/dashing/setup.bash workspace <workspace_name> workspace mkdir <workspace_name> mkdir <workspace_name>/src cd <workspace_name>/src Instead I would like to run ROS2 in a Powershell window. You source this catkin workspace so you can use it. Disclaimer: This tutorial is not an introduction to ROS or Docker. If you are like us, and have tried to setup ROS on a computer, you have probably been puzzled by how not straightforward this is. It seems not to, I did it with a source installation of moveit, and it does not work. @fujitatomoya I think everyone agrees that faster would be desired. Is it normal to just have one workspace which contains all packages you have built / downloaded (i.e. However, I also have downloaded another package, located in ~/ROS/src. Related question: https://answers.ros.org/question/302608/sourcing-setup-in-ros2-slow/. For example, is there a way to do the sourcing only once (e.g., at boot time), rather than repeating the process for all bashes? [1] There are more complicated scenarios where this isn't exactly true, but for the most part it should work and is how I do development. Create one now: $ mkdir ~/ros_catkin_ws $ cd ~/ros_catkin_ws Next we will want to download the source code for ROS packages so we can build them. ROS 2 packages promote software reuse. Caveat: If environment variables (e.g., PATH) are changed after first usage, before next usage, they are overwritten. Could this solved by replacing /opt/ros_$ROS_DISTRO/install/setup.bash with a file that effectively stores the changes to the environment settings like @christianrauch posted above? For others to explore potential solutions, is there a suggested toy benchmark in which people can tinker with and some pointers to what source to play with? AMENT_TRACE_SETUP_FILES=1 source /opt/ros/bouncy/local_setup.bash I'd say that you generally don't need to continually source the workspace. For the binary distribution, which is installed as a merged workspace, the effective change of the environment basically comes down to. While your workspace has only these two items sourcing install/setup.bash implicitly also sources /opt/ros/dashing/local_setup.bash. ros on DockerHub contains all the images you need to create your application. Results: Example workspace containing just example_interfaces and examples: The machine I mentioned above takes about twice as long. As long as the starting environment is the same and the content of the workspace hasn't changed you should be able to source the generated file instead of the usual setup file (which should be much faster) to setup the same environment. Each package might contain a mixture of code (e.g. I understand your point of view. @Karsten1987 If I recall correctly on your macOS the title bar of your terminal tab was constantly being updated while the sourcing was ongoing. I haven't tried this in a while, but wouldn't the problem arise if you're trying to use a Docker container, or similar, for deployment or development? If I then run echo $ROS_PACKAGE_PATH, it gives me /home/karnivaurus/catkin_ws/src:/opt/ros/indigo/share:/opt/ros/indigo/stacks. Services in ROS2 are another type of communication between different ROS2 nodes. Well occasionally send you account related emails. Alternatively, there should be an option to not recursively iterate through a merged workspace and just set the standard library and executable paths. - GitHub - ros2/ros_workspace: Package to set ROS environment and configuration variables for ROS 2.. Open a new terminal and source the "foxy" distribution. to your account. Please start posting anonymously - your entry will be published after you log in or create a new account. What I will do is add an option to the setting which enables auto sourcing workspace and have this on by default. It is easy to recognize them, their tags are simply the name of the ROS version you are looking for. Build the workspace from the workspace root-directory ( ros2_ws ). ROS is an open-source, meta-operating system for your robot. I assume that this is necessary since packages can be relocated, i.e. As it will include some arguments we recommend to create a script. The Docker container is responsible to run all the ROS part and connects to the host machine through TCP connection to start Webots. if the user doesn't supply their own template, put some token near the top, and attempt to fast aggregation beforehand?). Each folder within the source space contains one or more catkin packages. At AICA, we focus on simplifying the programming of industrial robotic arms. A workspace is a folder, where you can modify, build, and install packages. Creating a ROS or ROS2 workspace in Docker (Part 1) | by Baptiste Busch | Medium 500 Apologies, but something went wrong on our end. This is still too slow to do it in every terminal I open. A quite comprehensive sampling of different profile methods: https://stackoverflow.com/a/20855353/7829525 colcon build ls See that the ros2_ws directory now contains additional directories (build, install, log). Sourcing the default workspace by default in the .bashrc is therefore not an option. Software in ROS 2 is organized into packages. @LouisChen1905 I don't believe that will work for the same reason that Dirk mentioned: using ampersand will use a different process, and wait will simply block execution in the parent, but it will not try to "retrieve" the child processes environment variables and such. With ROS2 LTS versions being released, you might want to include this framework into your arsenal. Then, we want to specify that the shell is not interactive. Example module for ros2-workspace-template. That might help to pinpoint the bottlenecks. While this is a fairly easy task, it's always nice to automate even that, so you can get started right away. Start by building the core ROS packages. Those are located in different repositories. https://answers.ros.org/question/302608/sourcing-setup-in-ros2-slow/, https://github.com/colcon/colcon-bash/blob/master/colcon_bash/shell/template/prefix.bash.em, improve performance when setting up environment, https://stackoverflow.com/a/20855353/7829525, https://gist.github.com/EricCousineau-TRI/6870970d68f75d23061177a52932a5d1#file-bash_helper_functions-sh-L34, Sourcing setup script from Debian takes considerably longer than the local_setup script, (1) ROS2 Apps takes way too long to start [0]. We do not recommend that for using ROS and it is much better to create a user in the container that share the same rights as the host user. However, it will not update it if you already have it, preventing you to get the latest updates. So, we will do exactly that, but inside a Docker container. The cache-enabled local_setup.bash is attached as new_local_setup.bash.txt and can directly replace /opt/ros2_$ROS_DISTRO/install/local_setup.bash or that of any workspace. We will use vcstool for this. But this means that I cannot run the tutorial whilst also playing around with some other packages I've downloaded. turtlebot3_gazebo. . "/> The parameter server node Let's create a node in the src/ folder of "my_robot_bringup" package. It is quite common to have many "active" workspaces at a single time. Finally the configuration of ros2cli is run because of the bash completions. The ros_entrypoint.sh script handles sourcing the workspace configuration. On less powerfull devices like the Raspberry Pi, sourcing takes even longer (more than 10 seconds). you can add 'wait' after the last child processes. So we start by installing sudo and creating a new user: As you have noticed we also install some packages like git or wget. Then, open a new terminal, source your ROS2 workspace and execute the node with ros2 run. If you are familiar with ROS nomenclature, you will find again the bare-bones or core version of each release. The actual time for this small workspace is < 0.2s as you measured. Since sourcing the setup files of other workspaces is as slow as the main setup, I extended my script to allow sourcing those as well: ros2_quick_setup.sh. In the IDE I can run this in the background sometimes but not always and when finished update the IDE environment, but currently every time I execute commands that need the environment I go ahead and resource the workspace which I believe is excessive. That is why work is ongoing to improve the performance. Assuming that you have already Docker installed on your machine (if not you can follow the guide here), the first step is to find an image that will serve as a base. For a workspace with separated packages, I assume that LD_LIBRARY_PATH, PATH and PYTHONPATH will have multiple entries. source /opt/ros/foxy/setup.bash. For ROS1 you will need to go to osrf/ros and for ROS2 to osrf/ros2. For this we refer to the plethora of articles on both topics. Every program you write in ROS 2 will need to be inside a package. The command that takes the longest is in line 6528: I do not think that we could accept the following as product, since boot time is key especially consumer devices, which reflects on user experience.
