ROS messages for Ackermann steering
Home Page: http://wiki.ros.org/ackermann_msgs
Hello,
This isn't much of an issue, only a question.
I am new to ROS.
If i want to use an Arduino to control some steering servo motors, and I'd like to control this using ROS for an ackermann steered vehicle, what do I need?
How do i combine this with the ackermann_msgs?
Thanks,
Aaron
We want to release a new version of the webots_ros2 package and this is one of the packages we are missing
Other ROS packages depend on it. It should not remain in my personal github account.
This package has been failing on build.ros2.org since its release.
From the build log it seems that CMake is expecting to find std_msgs but no dependency on std_msgs is declared. Of course, it could also be the case that std_msgs isn't needed and the find_package call should be removed.
It would also be a good idea to check for other dependencies that are not reflected in the package.xml which would cut down on the number of iterations before a release can be built successfully.
CMake Error at CMakeLists.txt:18 (find_package):
By not providing "Findstd_msgs.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "std_msgs",
but CMake did not find one.
Could not find a package configuration file provided by "std_msgs" with any
of the following names:
std_msgsConfig.cmake
std_msgs-config.cmake
Add the installation prefix of "std_msgs" to CMAKE_PREFIX_PATH or set
"std_msgs_DIR" to a directory containing one of the above files. If
"std_msgs" provides a separate development package or SDK, be sure it has
been installed.

Hi :)
I am trying to use ackermann_msgs in a project, but the include can't find the cmake project.
I am using ROS-Melodic. Did I forget to do something?
My cmake file is is included.
CMakeLists.txt
This is the error message:
CMake Error at /opt/ros/melodic/share/catkin/cmake/catkinConfig.cmake:83 (find_package):
Could not find a package configuration file provided by "ackermann_msgs"

"ackermann_msgs_DIR" to a directory containing one of the above files. If
"ackermann_msgs" provides a separate development package or SDK, be sure it

In going through the Python3 transition tutorial I found that ackermann_msgs has Python 2 dependencies, and have no listed entry on the yaml where they document Noetic readiness.
Are there current efforts to support Noetic?
While I wrote the original ROS1 version nine years ago, I am now retired and unable to act as the maintainer. I have no knowledge of ROS2 practices.
@vincentrou : are you willing to take over maintenance for me?
I would like to integrate the four_wheel_steering_msgs in the official ROS repo for kinetic.
Actually a four_wheel_steering_controller is using it. I wish to integrate it in the ros_controllers
repo. ros-controls/ros_controllers#55 (comment)
What is the best thing to do for the four_wheel_steering_msgs
?
four_wheel_steering_msgs
vehicle_msgs
where we can put the two package ackermann_msgs
and four_wheel_steering_msgs
Hello,
Seems like rosdep cannot find this package, I am confused.
command used: rosdep install -i --from-path src --rosdistro foxy -y
I would appreciate any help in advance!
We're currently porting the CARLA Simulator ROS bridge to ROS2.
As it uses the ackermann_msgs, would it be possible for you to create a package release for ROS2 Eloquent and Foxy?
Thanks a lot.
Is there existing code that will convert these messages into the angles; speeds; etc for the left and right wheels? and possibly all 4 wheels if all 4 wheels are controlled with motors? These messages provide one steering angle (and speed, etc) for the rover (like a tricycle per the documentation); but we need to have a way to convert this angle (and speed, etc) into the angles for the individual wheels. Thanks
@jack-oquin Would you mind releasing ackermann_msgs
to ROS Noetic? It looks like all of its dependencies have been released, and I noticed it has been part of every ROS distro since Indigo.
I'm not sure how much work it will need. The Noetic Migration Guide or the guide about transitioning ROS packages to Python 3 may be useful.
i have install ‘ackermann_msgs’ by the command, and use ‘ackermann_msgs to write a publisher, when done, it occurs <error: ‘ackermann_msgs’ was not declared in this scope> cmakelist has already added find_package(ackermann_msgs REQUIRED) ament_target_dependencies(talker rclcpp std_msgs ackermann_msgs) same with the package.xml
