Hi @eblady ,

This post could be the solution: ROS2 Topics "ros2 topic echo /cmd_vel" fails - #7 by albertoezquerro

What you have to do is:

  1. Reset all the terminals on the course, that is, by clicking the red X button on every webshell.
  2. Then on every webshell that you will be using, you must type in these two commands before executing any other commands:
source /opt/ros/foxy/setup.bash
source /home/simulations/ros2_sims_ws/install/setup.bash

I believe this should definitely fix your problem. Let me know if you still have issues.
