I’m encountering an issue with the roslaunch command. When I try to run the command
roslaunch iri_wam_aff_demo start_demo.launch
, I receive an error indicating that the package iri_wam_aff_demo is not installed:
RLException: [start_demo.launch] is neither a launch file in package [iri_wam_aff_demo] nor is [iri_wam_aff_demo] a launch filename. The traceback for the exception was written to the log file.
Are you executing this command in the “6 Understanding ROS Services”?? Or are you on “5 Understanding ROS Basics”??
If you executed while on the unit 5, it won’t work because you are working with the kubuki robot and you don’t have the files for the robot arm.
Once you access to the lesson 6 your layout changes and you work the the robot arm and have the files available.
you can check if you have the necessary files executing this command:
Thank you for reaching out. I’m currently in the ‘6 Understanding ROS Services - Clients’, *(Unit 5 Services in ROS: Clients)
However, it seems that the package, is not appearing in the package list.
