* Run SLAM with Navigation 2 or tele-op to drive the robot and generate a map of an area for testing first. The directions below assume this has already been done or there is already a map of the area.


Note: * gazebo should be started with both libgazebo_ros_init.so and
libgazebo_ros_factory.so to work correctly. * spawn_entity node could not
remap /tf and /tf_static to tf and tf_static in the launch file yet, used only
for multi-robot situations. Instead it should be done as remapping argument
/tf:=tf  /tf_static:=tf_static  under ros2 tag in each plugin which publishs
transforms in the SDF file. It is essential to differentiate the tf's of the
different robot.

Dynamically composed bringup (based on [ ROS2 Composition
](https://docs.ros.org/en/galactic/Tutorials/Composition.html) ) is optional
for users. It can be used to compose all Nav2 nodes in a single process
instead of launching these nodes separately, which is useful for embedded
systems users that need to make optimizations due to harsh resource
constraints. Dynamically composed bringup is used by default, but can be
disabled by using the launch argument ` use_composition:=False ` .

###  Terminal 2: Launch your robot specific transforms


This allows to bring up multiple robots, cloning a single robot N times at
different positions in the map. The parameter are loaded from `
nav2_multirobot_params_all.yaml ` file by default. The multiple robots that
consists of name and initial pose in YAML format will be set on the command-
line. The format for each robot is ` robot_name={x: 0.0, y: 0.0, yaw: 0.0,
roll: 0.0, pitch: 0.0, yaw: 0.0} ` .

By Solution


This is a very flexible example for nav2 bringup that can be modified for
different maps/robots/hardware/worlds/etc. It is our expectation for an
application specific robot system that you're mirroring ` nav2_bringup `
package and modifying it for your specific maps/robots/bringup needs. This is
an applied and working demonstration for the default system bringup with many
options that can be easily modified.

# Map Server
The `Map Server` provides maps to the rest of the Nav2 system using both topic and
service interfaces. Map server will expose maps on the node bringup, but can also change maps using a `load_map` service during run-time, as well as save maps using a `save_map` server.
See its [Configuration Guide Page](https://navigation.ros.org/configuration/packages/configuring-map-server.html) for additional parameter descriptions.
### Architecture
In contrast to the ROS1 navigation map server, the nav2 map server will support a variety
of map types, and thus some aspects of the original code have been refactored to support
this new extensible framework.
Currently map server divides into tree parts:
- `map_server`
- `map_saver`
- `map_io` library
`map_server` is responsible for loading the map from a file through command-line interface
or by using service requests.
`map_saver` saves the map into a file. Like `map_server`, it has an ability to save the map from
command-line or by calling a service.
`map_io` - is a map input-output library. The library is designed to be an object-independent
in order to allow easily save/load map from external code just by calling necessary function.
This library is also used by `map_loader` and `map_saver` to work. Currently it contains
OccupancyGrid saving/loading functions moved from the rest part of map server code.
It is designed to be replaceable for a new IO library (e.g. for library with new map encoding
method or any other library supporting costmaps, multifloor maps, etc...).
### CLI-usage
#### Map Server
The `Map Server` is a composable ROS2 node. By default, there is a `map_server` executable that
instances one of these nodes, but it is possible to compose multiple map server nodes into
a single process, if desired.
The command line for the map server executable is slightly different that it was with ROS1.
With ROS1, one invoked the map server and passing the map YAML filename, like this:
```
$ map_server map.yaml
```
Where the YAML file specified contained the various map metadata, such as:
```
image: testmap.png
resolution: 0.1
origin: [2.0, 3.0, 1.0]
negate: 0
occupied_thresh: 0.65
free_thresh: 0.196

different positions in the map. The parameter are loaded from `
nav2_multirobot_params_all.yaml ` file by default. The multiple robots that
consists of name and initial pose in YAML format will be set on the command-

##  Launch Navigation2 in _Simulation_ with Gazebo


You can’t perform that action at this time.


## MapIO library
`MapIO` library contains following API functions declared in `map_io.hpp` to work with
OccupancyGrid maps:
- loadMapYaml(): Load and parse the given YAML file
- loadMapFromFile(): Load the image from map file and generate an OccupancyGrid
- loadMapFromYaml(): Load the map YAML, image from map file and generate an OccupancyGrid
- saveMapToFile(): Write OccupancyGrid map to file
## Services
As in ROS navigation, the `map_server` node provides a "map" service to get the map. See the nav_msgs/srv/GetMap.srv file for details.
NEW in ROS2 Eloquent, `map_server` also now provides a "load_map" service and `map_saver` -
a "save_map" service. See nav2_msgs/srv/LoadMap.srv and nav2_msgs/srv/SaveMap.srv for details.
For using these services `map_server`/`map_saver` should be launched as a continuously running
`nav2::LifecycleNode` node. In addition to the CLI, `Map Saver` has a functionality of server
handling incoming services. To run `Map Saver` in a server mode
`nav2_map_server/launch/map_saver_server.launch.py` launch-file could be used.
Service usage examples:
```
$ ros2 service call /map_server/load_map nav2_msgs/srv/LoadMap "{map_url: /ros/maps/map.yaml}"
$ ros2 service call /map_saver/save_map nav2_msgs/srv/SaveMap "{map_topic: map, map_url: my_map, image_format: pgm, map_mode: trinary, free_thresh: 0.25, occupied_thresh: 0.65}"

This is a very flexible example for nav2 bringup that can be modified for
different maps/robots/hardware/worlds/etc. It is our expectation for an
application specific robot system that you're mirroring ` nav2_bringup `
package and modifying it for your specific maps/robots/bringup needs. This is
an applied and working demonstration for the default system bringup with many
options that can be easily modified.

ROS2 are still in heavy development and there are some bugs and stability
issues being worked on, so please do not try this on a robot without taking
_heavy_ safety precautions. THE ROBOT MAY CRASH! * It is recommended to start

Dynamically composed bringup (based on [ ROS2 Composition
](https://docs.ros.org/en/galactic/Tutorials/Composition.html) ) is optional
for users. It can be used to compose all Nav2 nodes in a single process
instead of launching these nodes separately, which is useful for embedded
systems users that need to make optimizations due to harsh resource
constraints. Dynamically composed bringup is used by default, but can be
disabled by using the launch argument ` use_composition:=False ` .

###  Pre-requisites:


  * Gazebo installed on the system
  * gazebo_ros_pkgs for ROS2 installed on the system
  * A Gazebo world for simulating the robot (see Gazebo tutorials)
  * A map of that world saved to a map.pgm and map.yaml (see ROS Navigation tutorials)


##  Launch Navigation2 in simulation with Gazebo (first time users)

```
The Nav2 software retains the map YAML file format from Nav1, but uses the ROS2 parameter
mechanism to get the name of the YAML file to use. This effectively introduces a
level of indirection to get the map yaml filename. For example, for a node named 'map_server',
the parameter file would look like this:
```
# map_server_params.yaml
map_server:
    ros__parameters:
        yaml_filename: "map.yaml"
```
One can invoke the map service executable directly, passing the params file on the command line,
like this:
```
$ map_server __params:=map_server_params.yaml
```
There is also possibility of having multiple map server nodes in a single process, where the parameters file would separate the parameters by node name, like this:
```
# combined_params.yaml
map_server1:
    ros__parameters:
        yaml_filename: "some_map.yaml"
map_server2:
    ros__parameters:
        yaml_filename: "another_map.yaml"
```
Then, one would invoke this process with the params file that contains the parameters for both nodes:
```
$ process_with_multiple_map_servers __params:=combined_params.yaml
```
The parameter for the initial map (yaml_filename) has to be set, but an empty string can be used if no initial map should be loaded. In this case, no map is loaded during
on_configure or published during on_activate. The _load_map_-service should the be used to load and publish a map.
#### Map Saver
Like in ROS1 `map_saver` could be used as CLI-executable. It was renamed to `map_saver_cli`
and could be invoked by following command:
```
$ ros2 run nav2_map_server map_saver_cli [arguments] [--ros-args ROS remapping args]
```
## Currently Supported Map Types
- Occupancy grid (nav_msgs/msg/OccupancyGrid)
