Hello,
I have a problem with the controller.
My setup:
i use ros version galactic with the main brunch.
i use ur5 cb3.
All installation (driver for roboter and moveit) are done.
i start the driver "ros2 launch ur_bringup ur_control.launch.py ur_type:=ur5 robot_ip:=xxx use_fake_hardware:=false launch_rviz:=false
at this step no problem, but only one error. i dont use calibration, but i dint think, its important for the beginning.
second step, i launch: ros2 launch ur_bringup ur_moveit.launch.py ur_type:=ur5 robot_ip:=xxx use_fake_hardware:=false laucnh_rviz:=true
at this step no errors.
Last step, i move robot in rviz a little bit and then plan (no problem, no errors) and execute.
By execution moveit shell says: action client not connected to action server: joint_trajectory_controller/follow_joint_trajectory;
Failed to send trajectory part 1 of 1 to controller joint_trajectory_controller;
… ABORTED …
May be my Controller.yaml is not correct? or i forget something?
by the way, after controller failed, first shell with driver become also fail: Unable to read from harfware…
thank you for helping !
