ROS turtlesim - not responding to keyboard

Hi,

I just got started with ROS, and I bumped into the first wall when I was going through the tutorial in running turtlesim.

After I ran 'roscore', 'rosrun turtlesim turtlesim_node' and 'rosrun turtlesim turtle_teleop_key', it went through the settings fine. However, it is not responding to my keyboard control. I selected the terminal window of the turtle_teleop_key, but no luck.

While running them, I ran rxgraph to see the diagram, but it mentioned that the node communication failed, so I am predicting it's the problem with network setting, but I don't know how to fix it.

I would greatly appreciate for your help.

Thank you.

Are you able to move it via manually publishing to the turtlesim_node?

It's hard to help without further information. As a first step, have a look at the network setup page. rosnode info teleop_turtle might also provide some information.

put your mouse cursor on the terminal (which make it the current program to accept keys), and try to move your turtle again.
The problem may because you put your turtlesim at the most front, but turtlesim is not the true one to accept keys.
