Package Description

Package with the ROS-equivalent of PX4 uORB msgs

px4_msgs

GitHub license Build package

ROS 2 message definitions for the PX4 Autopilot project.

Building this package generates all the required interfaces to interface ROS 2 nodes with the PX4 internals.

Supported versions and compatibility

Depending on the PX4 and ROS versions you want to use, you need to checkout the appropriate branch of this package:

PX4 ROS 2 Ubuntu branch
v1.13 Foxy Ubuntu 20.04 release/1.13
v1.14 Foxy Ubuntu 20.04 release/1.14
v1.14 Humble Ubuntu 22.04 release/1.14
v1.14 Rolling Ubuntu 22.04 release/1.14
v1.15 Foxy Ubuntu 20.04 release/1.15
v1.15 Humble Ubuntu 22.04 release/1.15
v1.15 Rolling Ubuntu 22.04 release/1.15
main Foxy Ubuntu 22.04 main
main Humble Ubuntu 22.04 main
main Rolling Ubuntu 22.04 main

Messages Sync from PX4

When PX4 message definitions in the main branch of PX4 Autopilot change, a CI/CD pipeline automatically copies and pushes updated ROS message definitions to this repository. This ensures that this repository main branch and the PX4-Autopilot main branch are always up to date. However, if you are using a custom PX4 version and you modified existing messages or created new one, then you have to manually synchronize them in this repository:

Manual Message Sync

  • Checkout the correct branch associated to the PX4 version from which you detached you custom version.
  • Delete all *.msg and *.srv files in msg/ and srv/.
  • Copy all *.msg and *.srv files from PX4-Autopilot/msg/ and PX4-Autopilot/srv/ in msg/ and srv/, respectively. Assuming that this repository and the PX4-Autopilot repository are placed in your home folder, you can run:
  rm -f ~/px4_msgs/msg/*.msg
  rm -f ~/px4_msgs/srv/*.srv
  cp ~/PX4-Autopilot/msg/*.msg ~/px4_msgs/msg/
  cp ~/PX4-Autopilot/msg/versioned/*.msg ~/px4_msgs/msg/
  cp ~/PX4-Autopilot/srv/*.srv ~/px4_msgs/srv/

Note: The ROS 2 message generation pipeline requires all messages to be directly under msg/ and doesn’t support sub-directories.

Install, build and usage

Check Using colcon to build packages to understand how this can be built inside a workspace. Check the PX4 ROS 2 User Guide section on the PX4 documentation for further details on how this integrates PX4 and how to exchange messages with the autopilot.

Bug tracking and feature requests

  rm -f ~/px4_msgs/msg/*.msg
  rm -f ~/px4_msgs/srv/*.srv
  cp ~/PX4-Autopilot/msg/*.msg ~/px4_msgs/msg/
  cp ~/PX4-Autopilot/msg/versioned/*.msg ~/px4_msgs/msg/

Note: The ROS 2 message generation pipeline requires all messages to be directly under msg/ and doesn’t support sub-directories.

ROS 2 message definitions for the PX4 Autopilot project.

Building this package generates all the required interfaces to interface ROS 2 nodes with the PX4 internals.

Supported versions and compatibility

Depending on the PX4 and ROS versions you want to use, you need to checkout the appropriate branch of this package:

PX4 ROS 2 Ubuntu branch
v1.13 Foxy Ubuntu 20.04 release/1.13
v1.14 Foxy Ubuntu 20.04 release/1.14

Messages Sync from PX4

When PX4 message definitions in the main branch of PX4 Autopilot change, a CI/CD pipeline automatically copies and pushes updated ROS message definitions to this repository. This ensures that this repository main branch and the PX4-Autopilot main branch are always up to date. However, if you are using a custom PX4 version and you modified existing messages or created new one, then you have to manually synchronize them in this repository:

Manual Message Sync

  • Checkout the correct branch associated to the PX4 version from which you detached you custom version.
  • Delete all *.msg and *.srv files in msg/ and srv/.
  • Copy all *.msg and *.srv files from PX4-Autopilot/msg/ and PX4-Autopilot/srv/ in msg/ and srv/, respectively. Assuming that this repository and the PX4-Autopilot repository are placed in your home folder, you can run:
  rm -f ~/px4_msgs/msg/*.msg
  rm -f ~/px4_msgs/srv/*.srv
  cp ~/PX4-Autopilot/msg/*.msg ~/px4_msgs/msg/
  cp ~/PX4-Autopilot/msg/versioned/*.msg ~/px4_msgs/msg/
  cp ~/PX4-Autopilot/srv/*.srv ~/px4_msgs/srv/

Note: The ROS 2 message generation pipeline requires all messages to be directly under msg/ and doesn’t support sub-directories.

Install, build and usage

Check Using colcon to build packages to understand how this can be built inside a workspace. Check the PX4 ROS 2 User Guide section on the PX4 documentation for further details on how this integrates PX4 and how to exchange messages with the autopilot.

ROS 2 message definitions for the PX4 Autopilot project.

Building this package generates all the required interfaces to interface ROS 2 nodes with the PX4 internals.

Supported versions and compatibility

Depending on the PX4 and ROS versions you want to use, you need to checkout the appropriate branch of this package:

PX4 ROS 2 Ubuntu branch
v1.13 Foxy Ubuntu 20.04 release/1.13
v1.14 Foxy Ubuntu 20.04 release/1.14
v1.14 Humble Ubuntu 22.04 release/1.14
v1.14 Rolling Ubuntu 22.04 release/1.14
v1.15 Foxy Ubuntu 20.04 release/1.15
v1.15 Humble Ubuntu 22.04 release/1.15
v1.15 Rolling Ubuntu 22.04 release/1.15
main Foxy Ubuntu 22.04 main
main Humble Ubuntu 22.04 main
main Rolling Ubuntu 22.04 main

Messages Sync from PX4

When PX4 message definitions in the main branch of PX4 Autopilot change, a CI/CD pipeline automatically copies and pushes updated ROS message definitions to this repository. This ensures that this repository main branch and the PX4-Autopilot main branch are always up to date. However, if you are using a custom PX4 version and you modified existing messages or created new one, then you have to manually synchronize them in this repository:

Manual Message Sync

  • Checkout the correct branch associated to the PX4 version from which you detached you custom version.
  • Delete all *.msg and *.srv files in msg/ and srv/.
  • Copy all *.msg and *.srv files from PX4-Autopilot/msg/ and PX4-Autopilot/srv/ in msg/ and srv/, respectively. Assuming that this repository and the PX4-Autopilot repository are placed in your home folder, you can run:
  rm -f ~/px4_msgs/msg/*.msg
  rm -f ~/px4_msgs/srv/*.srv
  cp ~/PX4-Autopilot/msg/*.msg ~/px4_msgs/msg/
  cp ~/PX4-Autopilot/msg/versioned/*.msg ~/px4_msgs/msg/
  cp ~/PX4-Autopilot/srv/*.srv ~/px4_msgs/srv/

Note: The ROS 2 message generation pipeline requires all messages to be directly under msg/ and doesn’t support sub-directories.

Install, build and usage

Check Using colcon to build packages to understand how this can be built inside a workspace. Check the PX4 ROS 2 User Guide section on the PX4 documentation for further details on how this integrates PX4 and how to exchange messages with the autopilot.

GitHub license Build Status

This package contains the ROS(1) message definitions of the PX4 Pro ecosystem. Building this package generates all the required interfaces to interface ROS nodes with the PX4 autopilot internals, which use the uORB messaging API. Currently the messages of this package represent a dependency to px4_ros_com package ros1 branch. The interface with PX4 is only possible using the ros1_bridge and px4_ros_com, which bridges the ROS topics with the ROS2 topics.

uORB message definitions

The uORB message definitions, which represent the counter-part of these ROS messages found in this package, can be found on the PX4 Firmware repository.

How are these messsage definitions generated?

The PX4 Firmware Jenkins-based CI/CD deploys new messages or modifications to the current definitions with each build of the master branch of the PX4 Firmware. A future improvement will also include tagging and releasing this repository according to the tags/releases of the PX4 Firmware, for a more tide coupling between the message definitions.

Install, build and usage

Check this section of the ROS tutorials in order to understand how to create and build msg and srv files. Check the RTPS/ROS2 Interface section on the PX4 Devguide for further details on how this integrates with the px4_ros_com package.
