Hi @Dieudonne, can you tell us which unit are you working on?
If it is Unit 2 Basic Concepts did you follow the instructions of 2.6.1 ROS2 Node Basics?
There we explain that heartbeat.py
method starts and stops too fast for us to see it appear in ros2 node list
, then after you add a while loop you will be able to see it (more details of how to do that on the notebook of the course). Make sure you have followed these instructions, or let us know if you did them all to help you.
