Hello! I can’t seem to complete Exercise 3.1, I checked my code and it is the same as the solution. Below is the error message:
This is my launch file and CPP file:
I believe we dont need to have the service running right? Because in my launch file of this exercise, the include file (find…) line is to start the service first so the /trajectory_by_name service is already running once I roslaunch my launch file, all we need is to call the service so the robot moves. Please let me know what I am missing here. Thank you!
