Revision history [back]

Thank you. I can connect to roscore from machine #2. But, another problem.

I would like to control turtle (turtlesim example) in #1 using #2 keyboard.

So in #1,

$ rosrun turtlesim turtlesim_node

And in #2,

$ rosrun turtlesim turtle_teleop_key

However, I couldn't control. And I also ran the 'rxgraph' util, it seems not connected.

What's the problem?
