		Hello, Im working on a ROS project and I would like to do a 2D and 3D map using a RPLidar and a kinect using rviz and rtabmap, but I have son problems.
 I have launched the following commands:
  $ roslaunch freenect_launch freenect.launch  (for the kinect)
 $ roslaunch rplidar_ros rplidar.launch (for the laser sensor)
 $ roslaunch rtabmap_ros demo_hector_mapping.launch
  But, this last command gives me an error that I dont know how to solve:
  [rtabmap/rtabmap-6] process has died [pid 22232, exit code 127, cmd /home/palopter/catkin_ws/devel/lib/rtabmap_ros/rtabmap --delete_db_on_start scan:=/jn0/base_scan __name:=rtabmap __log:=/home/palopter/.ros/log/7cbebd34-e2c7-11ea-9133-002586f0c77a/rtabmap-rtabmap-6.log].
 log file: /home/palopter/.ros/log/7cbebd34-e2c7-11ea-9133-002586f0c77a/rtabmap-rtabmap-6*.log
  I have tried several things such as updating rtabmap but it doenst work.
  Any idea?
