Hi everyone.

I want to run Husky Robot ( ) in my Gazebo simulator. Current version for Husky in ROS is still in Indigo, and Kinetic version is still not released yet. So I cloned Husky code from into src folder in my new catkin workspace, compiled it using catkin_make, and run one of the launch file there :

roslaunch husky_gazebo husky_empty_world.launch

Then I met this errors:

Invalid parameter "robot_namespace"
XacroException('Invalid parameter "robot_namespace"',)
when instantiating macro: sick_lms1xx (/opt/ros/kinetic/share/lms1xx/urdf/sick_lms1xx.urdf.xacro)
in file: /home/myuserame/myworkspace/src/husky/husky_description/urdf/husky.urdf.xacro
while processing /home/myuserame/myworkspace/src/husky/husky_gazebo/launch/spawn_husky.launch:
while processing /home/myuserame/myworkspace/src/husky/husky_description/launch/description.launch:
Invalid < param > tag: Cannot load command parameter [robot_description]: command [/opt/ros/kinetic/lib/xacro/xacro '/home/myuserame/myworkspace/src/husky/husky_description/urdf/husky.urdf.xacro'     --inorder     robot_namespace:=/     laser_enabled:=true     kinect_enabled:=false     urdf_extras:=     ] returned with code [2]. 

Param xml is < param command="$(find xacro)/xacro '$(find husky_description)/urdf/husky.urdf.xacro'     --inorder     robot_namespace:=$(arg robot_namespace)     laser_enabled:=$(arg laser_enabled)     kinect_enabled:=$(arg kinect_enabled)     urdf_extras:=$(arg urdf_extras)     " name="robot_description"/ >
The traceback for the exception was written to the log file

Am I missing something?

Thank you!

Solved ! Sorry for my late confirmation

As i issued on their Github ( ), they current version of LMS1xx on repo is not updated yet and not supported the newest version of Husky. Then just like abrzozowski said, it needs to use newest version of LMS1xx from source at

Further details please look at

If you cloned repository, you should clone compatible lms1xx driver from too.
