Hi,
I'd like to update the multi husky simulator package as attached here: https://github.com/shehancaldera/multihusky_simulator. I'd like to discuss how I can collaborate on this sort of a project. Thanks -Shehan

while i execute the command roslaunch nre_simmultihusky multihusky.launch, i get the following errors

Hi, I hope you can see my message. Now I'm running with Ubuntu 16.04, ROS kinetic (ROS1)
I also working with my Gazebo multi ridgeback robots. But the problem is I don't know how to let EKF localization node works for multiple robots. From your git repo, I have seen that you done it properly. Therefore I would like to run your project to see how it works.
Note: I have download the original Husky package already and try to run your multihusky launch file. And found that

1. The kinect URDF file locazation was changed. So I have edit your mhusky.gazebo.xacro
   only one line as following
   <xacro:include filename="$(find husky_description)/urdf/accessories/kinect_camera.urdf.xacro"/>
2. When I launch the multihusky.launch. I have found the error below
   re/src/nre_simmultihusky/xacro/mhusky.gazebo.xacro' laser_enabled:=true ur5_enabled:=false kinect_enabled:=false nsp:=h1 tfpre:=h1_tf ] returned with code [2]. Param xml is <param command="$(find xacro)/xacro.py --inorder '$(find nre_simmu ltihusky)/xacro/mhusky.gazebo.xacro' laser_enabled:=$(arg laser_enabled ) ur5_enabled:=$(arg ur5_enabled) kinect_enabled:=$(arg kinect_ enabled) nsp:=$(arg namespace) tfpre:=$(arg tfpre) " na me="robot_description"/> The traceback for the exception was written to the log file
   Do you have any suggestion ??
