dynamixel_controllersTutorialsCreatingmetacontroller
I want to connect the dynamixel AX-64 motor with the PC, however, when I follow the tutorials and create a meta controller, I come across the following question.
I start the controller using the following command.
roslaunch my_dynamixel_tutorial start_meta_controller.launch
the ‘start_meta_controller.launch’ file is
<rosparam file="$(find my_dynamixel_tutorial)/tilt.yaml" command="load"/>
<node name="controller_spawner" pkg="dynamixel_controllers" type="controller_spawner.py"
args="--manager=dxl_manager
--port dxl_USB0
joint3_controller
joint4_controller
joint5_controller
"
output="screen"/>
<rosparam file="$(find my_dynamixel_tutorial)/joints_trajectory_controller.yaml" command="load"/>
<node name="controller_spawner_meta" pkg="dynamixel_controllers" type="controller_spawner.py"
args="--manager=dxl_manager
--type=meta
f_arm_controller
joint3_controller
joint4_controller
joint5_controller
"
output="screen"/>
And the error is:
… logging to /home/acer/.ros/log/63b699b2-a98e-11e7-b094-28e34739f5b2/roslaunch-acer-ubuntu-5609.log

Invalid roslaunch XML syntax: junk after document element: line 3, column 4

How to solve the problem? Thanks in advance.
