I enrolled in the course Ros for beginners in 5 days.
Went through the introduction.
How do I go to next section?
I checked the forum on this topic.Could’nt find any information.
It is such a basic step. Once I finish the introduction, the course should take me to the next level or point me in that direction, no?
Stuck here
Thanks for your help.
Hi Satya,
I understand that you found the button to move to the next unit.
There are two ways you can move to the next unit:
Push the button at the bottom line that says Next >
Also at the bottom line there is a button that indicates the current unit you are reviewing. If you press that button you will get a full list of the units available, so you can change quickly to another one.
Sorry, to bug you again
In ex 3.4
this command is failing:
user:/home/simulations/public_sim_ws/src/all/iri_wam/iri_wam_aff_demo$ roslaunch the_service_name start_serevice.launch
[start_serevice.launch] is neither a launch file in package [the_service_name] nor is [the_service_name] a launch file name
The traceback for the exception was written to the log file
The launch file is in
home/simulations/public_sim_ws/src/all/iri_wam$ find . | grep start_service.launch
./iri_wam_reproduce_trajectory/launch/start_service.launch
Rickt
I am still having problems. The package is not in catkin_ws/src
I posted the commands I executed on the “Get Help” screen. Did not want to duplicate the issue.
I am moving on to unit 4. I can come back and revisit unit 3 later.
Best,
Satya
Are you trying to launch a real service or just an example? I suppose the_service_name is not a real service/package name but just a fake name used to illustrate the point.
It was misleading because, the_service_name was used in the tutorial as service provided by the course.
Perhaps, the editors may want to edit the text or include (replae “the_service_name” with your own service name or some such wording)
When I was following the tutorial step by step, this got me lost…
