ROS2 Basic Development

Experiment 03 - Running ROS2 Topic Communication Nodes

This experiment implements dialogue testing by running two ROS2 topic nodes simultaneously.

Experiment Steps:

1) Manual Testing:

Open two new terminals

Terminal 1:

cd ros2_ws
source install/setup.bash
ros2 run arm_demo dialog_terminal --ros-args -p username:=alice -p mode:=interactive -p topic_name:=/chat

Terminal 2:

cd ros2_ws
source install/setup.bash
ros2 run arm_demo dialog_terminal --ros-args -p username:=bob -p mode:=interactive -p topic_name:=/chat

At this point, manually enter information in both terminals to achieve terminal topic dialogue:

2. Automatic Testing:

Open terminal and enter:

cd ros2_ws
source install/setup.bash
ros2 launch arm_demo topic_dialog.launch.py
