Hi, I am new to ROS, still very confused about the system yet. I am trying to programmaticaly set a navigation goal for my simulated turtle_bot. I followed this http://wiki.ros.org/navigation/Tutori... .

ON THE CONSOLE:

[ INFO] [1500435139.525509527, 13882.760000000]: Waiting for the move_base action server to come up
[ INFO] [1500435144.526530256, 13887.760000000]: Waiting for the move_base action server to come up
[ INFO] [1500435149.527434664, 13892.760000000]: Waiting for the move_base action server to come up
[ INFO] [1500435154.538756342, 13897.760000000]: Waiting for the move_base action server to come up

...

But I am waiting for the move_base to come up forever. I know this is probably a stupid question... How to I launch this move_base? rosrun or roslaunch something?

The first sentence in the prerequisites section of the tutorial you are following, states this:

This tutorial assumes basic knowledge of how to bring up and configure the navigation stack.

Without any previous knowledge, I would search for the turtlebot's navigation stack, which gets me here: http://wiki.ros.org/turtlebot_navigation

From the corresponding github page, I can see that in turtlebot_navigation there are several launch files, from which the amcl_demo.launch seems the most interesting! So,

roslaunch turtlebot_navigation amcl_demo.launch

Good luck!
