Hi everyone.

I want to run Husky Robot ( http://wiki.ros.org/Robots/Husky ) 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 https://github.com/husky/husky 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)

The traceback for the exception was written to the log file

Am I missing something?

Thank you!

Hello.

Currently I am trying to run several examples of gmapping and amcl from various robots. As i am still new in ROS, is there any guide to make our own algorithm for mapping/localization?

Thank you
