Turtlebot networking setup error
Hello, I have a problem with networking setup. I followed this tut.
http://www.ros.org/wiki/Robots/TurtleBot/Network%20Setup
at the last step, on my workstation, I ran
rostopic pub -r10 /hello std_msgs/String "hello"
and when I ran
rostopic echo /hello
on my turtlebot laptop I got this:
WARNING: topic [/hello] does not appear to be published yet
according to the tut.
The message "hello" begin printed about 10 times a second.
but that is not happening.
Any suggestions will be appreciated.
Thanks!
