What Is This?

This package contains the following ROS 2 nodes:

  1. listener
  2. talker
  3. add_two_ints_client
  4. add_two_ints_server
  5. set_parameters_callback
  6. add_two_ints_client_async
  7. listener_qos
  8. talker_qos
  9. listerner_serialized
  10. 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:

# In terminal running talker

QoS Listener & Talker

When executed correctly, strings should be printed to the terminal similar to what is shown below:

# In terminal running talker_qos

#...

Set Parameters Callback

[Before]

Run ros2 param get /set_parameters_callback param1 should print the following to the terminal:

Double value is: 0.0

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

Asynchronous Parameter Client

Running ros2 run demo_nodes_cpp parameter_blackboard should print the output to the terminal similar to what is shown below:

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

What Is This?

This package contains the following ROS 2 nodes:

  1. listener
  2. talker
  3. add_two_ints_client
  4. add_two_ints_server
  5. set_parameters_callback
  6. add_two_ints_client_async
  7. listener_qos
  8. talker_qos
  9. listerner_serialized
  10. 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
