moving openmanipulator gazebo simulation from command line not working

edit

I'm trying to use terminal to control my openManipulator_x through a gazebo simulation without much success. I've tried using the teleop keyboard controls and it's able to move the gazebo simulation. I'm completely new to ROS and robots and I have been trying to figure out how to use the command line interface to move the robot in certain directions. Below are the steps I took to try to move the arm simulation. Any help would be appreciated!

1. I launched roscore and rqt with the following commands:

   $ roscore

   $ rqt

2. Launched a controller (I set use_platform and use_moveit to false in the urdf file):

   $ roslaunch open_manipulator_controller open_manipulator_controller.launch

3. Launched an instance of gazebo:

   ~$ roslaunch open_manipulator_gazebo open_manipulator_gazebo.launch

4. I used the service caller in rqt to attempt to move the openmanipulator:

When I try to call /open_manipulator/goal_task_space_path_from_present_position_only, the arm doesn't move and I get this error from rqt

When I try to use /open_manipulator/moveit/set_kinematics_post, the service returns: is_planned bool = false. I also get this from the rqt in terminal:
