I'm in the midst of trying to set up turtlebot and I have encountered this problem.
When I type "roslaunch turtlebot_bringup robot.launch" on my laptop, the following message appears
Unable to contact my own server at [http://10.217.252.66:58698/].
This usually means that the network is not configured properly.
I tried pinging myself and it works. Any ideas what might be wrong? Thanks
I solved it. I changed the following in my .bashrc from
export ROS_MASTER_URI=http://10.217.252.66:11311
export ROS_HOSTNAME=10.217.252.66
to
export ROS_MASTER_URI=http://laptop_name:11311
export ROS_HOSTNAME=laptop_name
you need $ export ROS_HOSTNAME=localhost $ export ROS_MASTER_URI=http://localhost:11311
how can we add this? Actually i am using ubuntu on macbook via parallels and there is no export about localhost or network settings
export ROS_MASTER_URI=http://localhost:11311
export ROS_HOSTNAME=localhost
add these lines in bashrc.
I solved it! You can open .bashrc at first with gedit ~/.bashrc in the terminal and then add the code export ROS_HOSTNAME=localhost export ROS_MASTER_URI=http://localhost:11311 at the end of this .bashrc file.
