What Is This?
This package contains the following ROS 2 nodes:
listener
talker
add_two_ints_client
add_two_ints_server
set_parameters_callback
add_two_ints_client_async
listener_qos
talker_qos
listerner_serialized
async_param_client
Build
Run this command to build the package:
colcon build --packages-select demo_nodes_py
Run
Basic Listener & Talker
This runs talker
and listener
ROS 2 nodes which exchange the following string with incremeting integer:
Hello World:
# Open new terminal
ros2 run demo_nodes_py talker
# Open new terminal
ros2 run demo_nodes_py listener
Server & Client
This runs add_two_ints_client
and add_two_ints_server
ROS 2 client and server where the server processes two integers sent from the client and publishes its sum to the client to be printed out.
Server
# Open new terminal
ros2 run demo_nodes_py add_two_ints_server
Client [Synchronous]
# Open new terminal
ros2 run demo_nodes_py add_two_ints_client
Client [Asynchronous]
# Open new terminal
ros2 run demo_nodes_py add_two_ints_client_async
QoS Listener & Talker
Similar to previous, this runs talker_qos
and listener_qos
ROS 2 nodes which exchange messages using the Quality of Service (QoS) best effort policy.
# Open new terminal
ros2 run demo_nodes_py talker_qos
# Open new terminal
ros2 run demo_nodes_py listener_qos
Set Parameters Callback
This runs set_parameters_callback
ROS 2 node which triggers a callback when ROS 2 double parameter param1
is set. The callback then sets ROS 2 double parameter param2
to a fixed 4.0
:
# Open new terminal
ros2 run demo_nodes_py set_parameters_callback
Asynchronous Parameter Client
This runs async_param_client
ROS 2 node which demonstrates how to set, list, get, load and delete parameters from the parameter blackboard in an asynchronous manner:
# Open new terminal
ros2 run demo_nodes_cpp parameter_blackboard
For more details on parameter_blackboard, please refer to demo_nodes_cpp README.md.
# Open new terminal
ros2 run demo_nodes_py async_param_client
Serialized Subscriber
This runs serialized_subscriber
ROS 2 node that subscribes to the ROS 2 topic, /chatter
, and deserializes as well as prints out received strings:
# Open new terminal
ros2 run demo_nodes_py listener_serialized
Verify
Basic Listener & Talker
When executed correctly, strings should be printed to the terminal similar to what is shown below:

Run ros2 param get /set_parameters_callback param2
should print the following to the terminal:
Double value is 0.0
[Change]
Run ros2 param set /set_parameters_callback param1 28.0
should print the following to the terminal:
Set parameter successful
[After]
Run ros2 param get /set_parameters_callback param1
should print the following to the terminal:
Double value is: 28.0
Run ros2 param get /set_parameters_callback param2
should print the following to the terminal:
Double value is 4.0

What Is This?
This package contains the following ROS 2 nodes:
listener
talker
add_two_ints_client
add_two_ints_server
set_parameters_callback
add_two_ints_client_async
listener_qos
talker_qos
listerner_serialized
async_param_client
Build
Run this command to build the package:
colcon build --packages-select demo_nodes_py
Run
Basic Listener & Talker
This runs talker
and listener
ROS 2 nodes which exchange the following string with incremeting integer:
Hello World:
# Open new terminal
ros2 run demo_nodes_py talker
# Open new terminal
ros2 run demo_nodes_py listener
Server & Client
This runs add_two_ints_client
and add_two_ints_server
ROS 2 client and server where the server processes two integers sent from the client and publishes its sum to the client to be printed out.
Server
# Open new terminal
ros2 run demo_nodes_py add_two_ints_server
Client [Synchronous]
# Open new terminal
ros2 run demo_nodes_py add_two_ints_client
Client [Asynchronous]
# Open new terminal
ros2 run demo_nodes_py add_two_ints_client_async
QoS Listener & Talker
Similar to previous, this runs talker_qos
and listener_qos
ROS 2 nodes which exchange messages using the Quality of Service (QoS) best effort policy.
# Open new terminal
ros2 run demo_nodes_py talker_qos
# Open new terminal
ros2 run demo_nodes_py listener_qos
Set Parameters Callback
This runs set_parameters_callback
ROS 2 node which triggers a callback when ROS 2 double parameter param1
is set. The callback then sets ROS 2 double parameter param2
to a fixed 4.0
:
# Open new terminal
ros2 run demo_nodes_py set_parameters_callback
Asynchronous Parameter Client
This runs async_param_client
ROS 2 node which demonstrates how to set, list, get, load and delete parameters from the parameter blackboard in an asynchronous manner:
# Open new terminal
ros2 run demo_nodes_cpp parameter_blackboard
For more details on parameter_blackboard, please refer to demo_nodes_cpp README.md.
# Open new terminal
ros2 run demo_nodes_py async_param_client
Serialized Subscriber
This runs serialized_subscriber
ROS 2 node that subscribes to the ROS 2 topic, /chatter
, and deserializes as well as prints out received strings:
# Open new terminal
ros2 run demo_nodes_py listener_serialized
Verify
Basic Listener & Talker
When executed correctly, strings should be printed to the terminal similar to what is shown below:
