ROS2

Hello, I have problems with chapter 2 " ros2 launch br2_tiago sim.launch.py".

I get the following error messages:

play_motion2_node-10] [ERROR] [1683104855.352795642] [play_motion2]: Service /controller_manager/list_controllers not available. [play_motion2_node-10] [ERROR] [1683104855.352955540] [play_motion2]: There are no active JointTrajectory controllers available [tuck_arm.py-15] [ERROR] [1683104855.369452866] [arm_tucker]: play_motion2 is not ready

I have the following packages installed (and more ;-) ) : controller_manager controller_manager_msgs play_motion2 play_motion2_msgs

I followed the installation guidelines in the presentation.

What has gone wrong?

Thanks, Verena
