Hi, I am currently facing the same problem. Ubuntu 20.04.3 LTS OpenMANIPULATOR-P (default settings) U2D2 (port latency 1ms)

And I used same command with you. Now , I can't using GUI or Keyboard teleop control it. I can only use "Actuator" and "read" button , everything else causes a freeze. So, how can fix it. thank you. By the way, I'm sure all of my joint are all within the working range (1.571 rad).

Hi @DarrylHsu0105 In case of operating the OpenMANIPULATOR-P, you should use the openmanipulator-p package. https://github.com/ROBOTIS-GIT/open_manipulator_p Which ROS version do you use?
