The error is right there:

Failed to contact master

For rosrun, you need to start a ROS master Otherweise, no subscriptions etc. will work. Simply open another terminal and type roscore.

I tried this and i'm getting this message:

Unable to contact my own server at [ http://IP_OF_TURTLEBOT:37529/ ].

This usually means that the network is not configured properly.

A common cause is that the machine cannot ping itself. Please check

for errors by running: ping ip_of_turtlebot
