This is the primary documentation for the MoveIt project.
This repository is built and deployed automatically by GitHub Actions:
We strongly encourage you to help improve MoveIt's documentation. Please consider helping improve the tutorials, port old ones from ROS 1, and write new tutorials. We recommend you read the quality standards below as well as the How to Write a MoveIt Tutorial page.
If you find an issue with the tutorials you are not able to fix yourself, please open an issue on GitHub or open a PR with proposed changes.
An issue has been created for each tutorial to be ported to ROS 2. At the top of each tutorial, there is a tag: ":moveit1:", remove the tag after the tutorial has been successfully updated.
Below are some links to help with the ports.
Follow the MoveIt Source Build instructions to set up a colcon workspace with MoveIt from the source.
Open a command line to your colcon workspace:
cd $COLCON_WS/src
Download the MoveIt Tutorials source code:
git clone https://github.com/moveit/moveit2_tutorials.git
vcs import < moveit2_tutorials/moveit2_tutorials.repos
rosdep install -r --from-paths . --ignore-src --rosdistro rolling -y
Configure and build the workspace:
cd $COLCON_WS
colcon build --event-handlers desktop_notification- status- --cmake-args -DCMAKE_BUILD_TYPE=Release
If you want to test the tutorials by generating the HTML pages locally on your machine, you can use the build_locally.sh
script in this repo.
If you are using Ubuntu 24.04 (or Python 3.11 or greater), you should first create a virtual environment.
python3 -m venv .venv
source .venv/bin/activate
Then, issue the following commands in the root of the moveit2_tutorials
package:
cd $COLCON_WS/src/moveit2_tutorials
export ROS_DISTRO=rolling # 24.04
source /opt/ros/$ROS_DISTRO/setup.bash
./build_locally.sh
The local website <LOCAL_PACKAGE_PATH>/build/html/index.html
should automatically open in your web browser.
- noinstall skip the dependencies install step to speed up the script
- loop automatically rebuilds the HTML if a change is detected
These tutorials use the reStructuredText format commonly used in the Sphinx "Python Documentation Generator". This unfortunately differs from the common Markdown format, but its advantage is that it supports embedding code directly from source files for inline code tutorials.
Code Formatting
- These tutorials use the same style guidelines as the MoveIt project. When modifying or adding to these tutorials, it is required that code is auto-formatted using clang format. To check and apply the style guidelines we use pre-commit.
- Tutorials should exemplify best coding practices. If a contribution wouldn't pass review in the MoveIt project, then it shouldn't pass review in the tutorials.
- Relevant code should be included and explained using the
.. tutorial-formatter::
tag. - Irrelevant code should be excluded from the generated HTML using the
BEGIN_TUTORIAL
,END_TUTORIAL
,BEGIN_SUB_TUTORIAL
, andEND_SUB_TUTORIAL
tags. - Whenever possible, links should be created using the
extlinks
dictionary defined inconf.py
. - All demo code should be runnable from within the
moveit2_tutorials
package. - Python code should be run using
ros2 run
.
Style
- Each tutorial should be focused on teaching the user one feature or interface within MoveIt.
- Tutorials should flow from show to tell with videos and demos at the beginning followed by explanations.
- New tutorials should match the formatting, style, and flow of existing tutorials whenever possible.
pre-commit
pre-commit is a tool that is used in moveit2_tutorials to check and apply style guidelines automatically. To install pre-commit into your system:
pip3 install pre-commit
Then under the moveit2_tutorials directory install the git hooks like this:
cd $COLCON_WS/src/moveit2_tutorials && pre-commit install
With this pre-commit will automatically run and check a list of styling including clang-format, end of files, and trailing whitespaces whenever you run git commit
. To run pre-commit any time other than git commit
:
cd $COLCON_WS/src/moveit2_tutorials && pre-commit run -a
The standard way to include an image in reStructuredText is
.. image:: filename.png
:width: 700px
This assumes that filename.png
is in the same folder as the source .rst
file. Images linked in this way will automatically be copied to the appropriate folder in the build.
Do not include animated gifs as the file format leads to very large files. Use a video format like webm
and see the section on the local video below.
You can embed video with raw HTML, like in this example from the Pick and Place Tutorial.
.. raw:: html
<div style="position: relative; padding-bottom: 5%; height: 0; overflow: hidden; max-width: 100%; height: auto;">
<iframe width="700px" height="400px" src="https://www.youtube.com/embed/QBJPxx_63Bs?rel=0" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>
</div>
This includes YouTube's suggested embed HTML.
To embed a video that is included in this repository, you also will use raw HTML, like this example from the Quickstart in RViz tutorial.
.. raw:: html
<video width="700px" controls="true" autoplay="true" loop="true">
<source src="../../../_static/videos/rviz_joints_nullspace.webm" type="video/webm">
The joints move while the end effector stays still
</video>
Note that the video file is in the _static/videos
folder instead of the same folder.
