$ sudo apt-get install xterm
Create launch.sh file with the following content
#!/bin/sh
xterm -e " gazebo " &
sleep 5
xterm -e " source /opt/ros/kinetic/setup.bash; roscore" &
sleep 5
xterm -e " rosrun rviz rviz"
Needs to have run permissions.
$ chmod +x ~/catkin_ws/src/launch.sh
Run launch.sh to test Gazebo and RViz are working.
$ ~/catkin_ws/src/launch.sh
$ mkdir -p ~/catkin_ws/src
$ cd ~/catkin_ws/src
$ catkin_init_workspace
$ cd ..
$ catkin_make

Sending parameter with roslaunch may cause error.
$ roslaunch turtlebot_gazebo turtlebot_world.launch world_file:=~/catkin_ws/src/worlds/u.world
Caused following error
terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::lock_error> >'
what(): boost: mutex lock failed in pthread_mutex_lock: Invalid argument
Aborted (core dumped)
Therefore, the turtlebot_world.launch file was altered to accept u.world as the default world file.
test_slam.sh file content:
#!/bin/sh
#xterm -e " roslaunch turtlebot_gazebo turtlebot_world.launch world_file:=~/catkin_ws/src/worlds/u.world " &
xterm -e " roslaunch turtlebot_gazebo turtlebot_world.launch " &

Needs to have run permissions.
$ chmod +x ~/catkin_ws/src/wall_follower.sh
Run wall_follower.sh to autonomously navigate and create map.
$ ~/catkin_ws/src/wall_follower.sh
Sending map_file parameter caused file not found error. Therefore, amcl_demo.launch file changed to accept uamp.yaml file as the default map.
$ roslaunch turtlebot_gazebo amcl_demo.launch map_file:=~/catkin_ws/src/worlds/umap.yaml
Needs to have run permissions.
$ chmod +x ~/catkin_ws/src/test_navigation.sh
Run test_navigation.sh to test navigation is working.

$ ~/catkin_ws/src/pick_objects.sh
Needs to have run permissions.
$ chmod +x src/add_markers.sh
Run add_markers.sh to add and remove a marker on the pick up and drop off locations.
$ ~/catkin_ws/src/add_markers.sh
Note: The last version works but not as the Project part 11 Modeling Virtual Objects, since the logic has changed, the robot is required to reach to the marker to continue.
Needs to have run permissions.
$ chmod +x src/home_service.sh
Run home_service.sh to pick and drop marker to specified locations.
