c++ sample
Run example for subscribe, you can open a terminal to executing command:
ros2 run demo_nodes_cpp listener
Open a new terminal to executing command to publish:
ros2 run demo_nodes_cpp talker
rclnodejs sample
Run example for subscribe, you can open a terminal to executing command:
cd /usr/local/Advantech/ros/foxy/sample_code/rclnodejs_sample node sub.js
Open a new terminal to executing command to publish:
cd /usr/local/Advantech/ros/foxy/sample_code/rclnodejs_sample node pub.js
rclpy sample
Run example for subscribe, you can open a terminal to executing command:
cd /usr/local/Advantech/ros/foxy/sample_code/rclpy_sample python3 subscriber.py
Open a new terminal to executing command to publish:
cd /usr/local/Advantech/ros/foxy/sample_code/rclpy_sample python3 publish.py
turtlesim
Open a terminal to start turtlesim by executing command:
ros2 run turtlesim turtlesim_node
The simulator window should appear, with a random turtle in the center.
Open a new terminal, run a new node to control the turtle in the first node by executing command:
ros2 run turtlesim turtle_teleop_key
Use the arrow keys on your keyboard to control the turtle. It will move around the screen, using its attached “pen” to draw the path it followed so far.
