2017-04-18 10:53:38 -0500	asked a question	Some problems of conversion xacro to urdf (Mastering ROS Chapter 2) Hi,everyone. I'm reading the book《mastering ros robotics programming》,and in chapter 2 I'm meeting some problems when I try to convert the xacro file to urdf file in the demo "seven_dof_arm". My system is Ubuntu 16.04 & Ros Kinetic. The xacro file and it's incluing sensor file are downloaded from https://github.com/qboticslabs/master... When I run the command" rosrun xacro xacro.py seven_dof_arm.xacro > seven_dof_arm.urdf "， the terminal shows: xacro: Traditional processing is deprecated. Switch to --inorder processing! To check for compatibility of your document, use option --check-order. For more infos, see http://wiki.ros.org/xacro#Processing_... inconsistent namespace redefinitions for xmlns:xacro: old: http://www.ros.org/wiki/xacro1 new: http://ros.org/wiki/xacro1 (/home/dd/catkin_workspace/src/mastering_ros_robot_description_pkg/urdf/sensors/xtion_pro_live.urdf.xacro) deprecated: xacro tags should be prepended with 'xacro' xml namespace. Use the following script to fix incorrect usage: find . -iname "*.xacro" \| xargs sed -i 's#<([/]\?)(if\\|unless\\|include\\|arg\\|property\\|macro\\|insert_block)#<\1xacro:\2#g' when processing file: seven_dof_arm.xacro unknown macro name: xacro:base XacroException(u'unknown macro name: xacro:base',) when processing file: seven_dof_arm.xacro Can anyone help me ? Thanks.
