Hello,

I used this to launch: roslaunch turtlebotgazebo turtlebotworld.launch And I ended up with the below in red:

[gazebo-2] process has died [pid 27527, exit code 134, cmd /opt/ros/indigo/lib/gazeboros/gzserver -e ode /opt/ros/indigo/share/turtlebotgazebo/worlds/playground.world _name:=gazebo _log:=/home/logan/.ros/log/7a97476a-8c4f-11e6-ac72-4c8093b62d1c/gazebo-2.log]. log file: /home/logan/.ros/log/7a97476a-8c4f-11e6-ac72-4c8093b62d1c/gazebo-2*.log

I have no clue what to do, any help is appreciated.
