Cannot communicate/ping the turtlesim
I am going through the tutorials and have reached point of using the turtlesim for learning about nodes, etc. I am trying to ping the turtlesim node, but there is no communication with the turtlesim. I have it running and roscore from 2 separate terminals and am pinging it from a third. Pinging the rosout node does work.
Here is the rosnode info for turtlesim:
Node [/turtlesim] Publications: * /turtle1/color_sensor [turtlesim/Color] * /rosout [rosgraph_msgs/Log] * /turtle1/pose [turtlesim/Pose]
