Trajectory controller node missing

Hi, I am trying to execute ros2 run rqt_joint_trajectory_controller rqt_joint_trajectory_controller command but everytime I get the same output saying that the package has not been found.

Any solutions?

PD: I have one more question. Why do the test_trajectories.cpp files have errors? I have followed the tutorial and have not added anything from my own. I have tried everything to get rid of the errors but they just dont seem to go. The planning and execution seems to be working fine but the files have errors. Could anyone please be able to explain why and/or how to fix this? Thanks again.

Hello @tumoney84 ,

It looks like you have to install the package. Try with the following commands:

sudo apt update
sudo apt install ros-humble-rqt-joint-trajectory-controller

About the errors in the code, you can simply ignore them. It’s a problem with the code editor, nothing to do with your actual code.


Thanks for the help and clarification!
