I have launched the robot hardware nodes using the following command:

$ roslaunch chefbot_bringup robot_standalone.launch

than later I have run the amcl launch file using the following command:

roslaunch chefbot_bringup amcl_demo.launch map_file:=/home/marcus/catkin_ws/src/Chef_Bot/Chefbot_Master/chefbot/chefbot_simulator/chefbot_gazebo/maps/room.yaml

Finally I have executed the following command to visualize the generated map in Rviz ( map of the room I configured with the robot in it)

$ roslaunch chefbot_bringup view_navigation.launch

So the map in Rviz did not open, and I received the following messages:

... logging to /home/marcus/.ros/log/012a62d0-a8c2-11e9-a425-c82158f9534e/roslaunch-marcus-Aspire-VX5-591G-14849.log

I am not understanding what is going on...there is not an error message in RED color, as it is common...so I am confused how to solve this issue. Could some expert help me?

Thanks in advance
