Invalid <param> tag Error?
when I run roslaunch rbx1_bringup fake_turtlebot.launch, there is something wrong like this:
Invalid <param> tag: Cannot load command parameter [robot_description]: command [/opt/ros/hydro/share/xacro/xacro.py '/home/snoopy/myspace/src/turtlebot_description/urdf/turtlebot.urdf.xacro'] returned with code [1].
Param xml is <param command="$(arg urdf_file)" name="robot_description"/>
I've searched a lot, but still don't know how to solve this.
What's the value of
$(arg urdf_file)?I am running into same problem. Did you find a solution yet?
