rosrun joint_trajectory_controller joint_trajectory_controller

Goodnight.

I am following the course faithfully, in lesson two it asks me to write the following code in the console:

$ rosrun joint_trajectory_controller joint_trajectory_controller

But I get the following error message:

user:~/catkin_ws/src$ rosrun joint_trajectory_controller joint_trajectory_controller
[rosrun] Couldn’t find executable named joint_trajectory_controller below /opt/ros/kinetic/share/joint_trajectory_controller
[rosrun] Found the following, but they’re either not files,
[rosrun] or not executable:
[rosrun] /opt/ros/kinetic/share/joint_trajectory_controller

Can you help me solve this problem?

Hello @Arnolvalencia1 ,

The proper command to use now is:

rosrun rqt_joint_trajectory_controller rqt_joint_trajectory_controller

I’ve already updated the notebook to modify this.

thanks the code worked
