First we’ll run ` robot_state_publisher ` , which can be a bit confusing when
doing it for the first time as passing in the URDF file in is a bit tricky.
The URDF is taken on the parameter ` robot_description ` , so the command will
look something like:


The first step in doing this is to make sure we have a URDF file for our
robot. This is a kind of configuration file where we can specify all sorts of
physical characteristics of the robot’s components, such as their size, shape,
colour, and more. There are many tutorials available for writing URDF files,
but for now we can use [ this example file
](https://gist.github.com/joshnewans/69cb8a049fb4606b0a6bdecd6933164e) which
is for a manipulator similar to the one from the introduction.

If we take a look at the resulting file (either opening in a file browser, or
from the terminal with ` atril frames.pdf ` ), we can see the tree visualised.
Note that the arrows here are reversed compared to RViz (and are the same as
in the introduction). We won’t worry too much about the rest of the

Underneath, the ` tf2 ` libraries are still using topics ( ` /tf ` and `

The ` odom ` frame is useful as an accurate, short-term local reference, but
drift makes it a poor frame for long-term reference.
###  map
The coordinate frame called ` map ` is a world fixed frame, with its Z-axis
pointing upwards. The pose of a mobile platform, relative to the ` map `
frame, should not significantly drift over time. The ` map ` frame is not
continuous, meaning the pose of a mobile platform in the ` map ` frame can
change in discrete jumps at any time.
In a typical setup, a localization component constantly re-computes the robot
pose in the ` map ` frame based on sensor observations, therefore eliminating
drift, but causing discrete jumps when new sensor information arrives.
The ` map ` frame is useful as a long-term global reference, but discrete
jumps in position estimators make it a poor reference frame for local sensing
and acting.
**Map Conventions**
Map coordinate frames can either be referenced globally or to an application
specific position. A example of an application specific positioning might be
Mean Sea Level  [3]  according to EGM1996  [4]  such that the z position in
the map frame is equivalent to meters above sea level. Whatever the choice is
the most important part is that the choice of reference position is clearly
documented for users to avoid confusion.
When defining coordinate frames with respect to a global reference like the
earth:

  * The default should be to align the x-axis east, y-axis north, and the z-axis up at the origin of the coordinate frame.
  * If there is no other reference the default position of the z-axis should be zero at the height of the WGS84 ellipsoid.
In the case that there are application specific requirements for which the
above cannot be satistfied as many as possible should still be met.
An example of an application which cannot meet the above requirements is a
robot starting up without an external reference device such as a GPS, compass,
nor altimeter. But if the robot still has an accelerometer it can intialize
the map at its current location with the z axis upward.
If the robot has a compass heading as startup it can then also initialize x
east, y north.
And if the robot has an altimeter estimate at startup it can initialize the
height at MSL.
The conventions above are strongly recommended for unstructured environments.
**Map Conventions in Structured Environments**
In structured environments aligning the map with the environment may be more
useful. An example structured environment such as an office building interior,

The choice of steering mechanism for a mobile robot depends on the specific
application requirements and design constraints. Differential steering is a
simple and efficient choice for basic mobility tasks, but it may struggle with
tight turns or challenging terrains. Ackermann steering provides better
maneuverability and stability, making it suitable for applications that
require precise steering control. Omni-directional steering mechanisms offer
the most flexibility but can be more complex to implement. By understanding
these different steering mechanisms, designers can choose the most suitable
option for their mobile robot and maximize its performance in various
environments.

To check if these worked, we’ll use the ROS visualisation tool, RViz.


A brushless DC motor has been designed by Printed Motor Works for use in
dynamic vehicle testing. The high power-density motor is part of a steering
robot developed by Anthony Best Dynamics.

Our transforms won’t appear just yet, because we haven’t told RViz which frame
to use as a reference (it defaults to ` map ` , which doesn’t exist right
now). Up in the top-left corner we can select ` world ` as our fixed frame.

I see other similar questions here, but nothing that answered my specific
inquiries about tf: 1\. Is it recommended to use a separate tf server (as in
its own node)? 1\. Should URDF be used for statically-linked robots like
quadcopters with a few attached sensors? 1\. When is a tf_state_publisher used
(from a launch file, say), as opposed to a tf broadcaster in code?

To solve these problems, we need to first assign coordinate systems, or
_frames_ to appropriate components of our system. Next, we would need to
define _transforms_ between the frames. A transform tells us the translations
and rotations required to turn one frame into a different frame, and can be
easily reversed to go the other way.

Dealing with wheel slippage and sinkage requires a combination of mechanical
design considerations, sensor-based feedback systems, and intelligent control
algorithms. By integrating real-time sensors to monitor wheel motion, terrain
conditions, and slip/sinkage detection, robots can adapt their control
strategies to optimize traction and minimize the impact of slippage and
sinkage.

Downloads


  Compile ros_ign

The following steps are for Linux and OSX.

  1. Create a colcon workspace:

        # Setup the workspace
    mkdir -p ~/ws/src
    cd ~/ws/src

    # Download needed software
    git clone https://github.com/osrf/ros_ign.git -b galactic

  2. Install dependencies (this may also install Ignition):

        cd ~/ws
    rosdep install -r --from-paths src -i -y --rosdistro galactic

> If ` rosdep ` fails to install Ignition libraries and you have not installed
> them before, please follow [ Ignition installation instructions
> ](https://ignitionrobotics.org/docs/latest/install) .

  3. Build the workspace:

        # Source ROS distro's setup.bash
    source /opt/ros/galactic/setup.bash

    # Build and install into workspace
    cd ~/ws
    colcon build

Hi I’m having an issue running the docker image for ROS2 Galactic on my Jetson
Nano 4GB, Model B01, running Jetpack-SDK-4.6.3 (after upgrading from 4.6.1)


Note: you will have to replace “your_target_architecture” with your target
architecture (e.g: “aarch64le” or “x86_64).

3- If a /tmp directory does not exist, add one on your target. Please note
that this will require having a writable / partition, otherwise you can create
another partition and mount it on top of / or /tmp

  Ignition

Install either [ Edifice or Fortress ](https://ignitionrobotics.org/docs) .

Set the ` IGNITION_VERSION ` environment variable to the Ignition version
you'd like to compile against. For example:

    export IGNITION_VERSION=edifice

> You only need to set this variable when compiling, not when running.

` apt ` is completely correct when it tells you it cannot find ` ros-galactic-

Hi [ @andrew.cra2019 ](/u/andrew.cra2019) , it looks like the container is
running since you are at the ` root@rosnet:/# ` (and then you exited the

is why it didn’t fetch it again.

###  Add the new Node to Plugin Setup


colcon build


As you can see, the MyRobotDriver class implements three methods.


  // To be redesigned when mRangeFinder->getPointCloud() will be implemented on Webots side.
  void Ros2RangeFinder::publishPointCloud() {
    auto image = wb_range_finder_get_range_image(mRangeFinder);
    if (image) {
      mPointCloudMessage.header.stamp = mNode->get_clock()->now();

4. If Webots couldn’t be found, ` webots_ros2  ` will show a window offering the automatic installation of the latest compatible version of Webots.


Use the ROS2 launch command to start demo packages (e.g. `
webots_ros2_universal_robot ` ):


    cd ~/ros2_ws/src
    ros2 pkg create --build-type ament_python --license Apache-2.0 --node-name my_webot_driver hello_webots --dependencies rclpy geometry_msgs webots_ros2_driver


###  Add added Files to Plugin Setup


ros2 topic pub /cmd_vel geometry_msgs/Twist  "linear: { x: 0.1 }"


Create a ROS 2 workspace with its ` src  ` directory.


###  Edit the Driver Plugin


[ Previous ](Simulation-Webots.html "Webots") [ Next  ](Installation-
Windows.html "Installation \(Windows\)")


###  Create the Launch File


    // Image publisher
    mImagePublisher =
      mNode->create_publisher<sensor_msgs::msg::Image>(mTopicName + mImageSuffix, rclcpp::SensorDataQoS().reliable());
    mImageMessage.header.frame_id = mFrameName;
    mImageMessage.height = height;
    mImageMessage.width = width;
    mImageMessage.is_bigendian = false;

The robot_name parameter is used to define the name of the robot the driver
should connect to. The ` robot_description ` parameter holds the path to the
**URDF** file which refers to the ` MyRobotDriver ` plugin. You can see the `
WebotsController ` node as the interface that connects your controller plugin
to the target robot.

Add the installed version:


[ GitHub  ](https://github.com/mpolinowski)


First source the ROS 2 environment, if not done already.


###  Declare the Plugin


` webots_ros2_driver ` contains plugins to interface most of Webots devices
with ROS2 directly. These plugins can be loaded using the ` <device> ` tag in
the URDF file of the robot. The list of all existing interfaces and the
corresponding parameters can be found on the [ devices reference page
](https://github.com/cyberbotics/webots_ros2/wiki/References-Devices) \- e.g.
currently available sensors devices:


The type attribute specifies the path to the class given by the hierarchical
structure of files. ` webots_ros2_driver ` is responsible for loading the
class based on the specified package and modules.
