Hi all! I'm following the tutorial of industrial [Create_a_MoveIt_Pkg_for_an_Industrial_Robot](http://wiki.ros.org/Industrial/Tutorials/Create_a_MoveIt_Pkg_for_an_Industrial_Robot). When I stepped into the 2.Update Configuration Files and completed the moveit_planning_execution.launch, I tried roslaunch it,but it failed. Something was wrong like this:
redefining global property: pi
when processing file: /home/shantengfei/catkin_ws/src/jaka/urdf/jaka.urdf.xacro
while processing /home/shantengfei/catkin_ws/src/jaka_ur_moveit_config/launch/move_group.launch:
while processing /home/shantengfei/catkin_ws/src/jaka_ur_moveit_config/launch/trajectory_execution.launch.xml:
while processing /home/shantengfei/catkin_ws/src/jaka_ur_moveit_config/launch/jakaUr_moveit_controller_manager.launch.xml:
Invalid roslaunch XML syntax: not well-formed (invalid token): line 8, column 0
The traceback for the exception was written to the log file
. I defined the pi in xacro.So is this wrong? In addition, there is a tip
**"Invalid roslaunch XML syntax: not well-formed (invalid token): line 8, column 0
The traceback for the exception was written to the log file"**.
Here is the launch file:
