- package: my_robot_controller
- ros2 executable name: test_node --> installed with colcon build & will be run with the command line (terminal)
- file name: my_first_node --> where we write our code
- node name: first_node --> node name in ros2 functionalities
-
Tip 1: you can name all three (ros2 executable, file, node) names the same
-
Tip 2: use "colcon build --symlink-install" for build convenience
-
Rule 1: everytime you want to run a modified python code, you need to use colcon build. similar to "make" command in C.
-
Rule 2: node needs to be running for commands "rqt_graph", "ros2 node list" to be effective
- Install python
- Install pylance
- Install ros2 =================== if vscode cannot read ros2 modules (i.e rclpy), do the following:
