I can't visualize anything about nav2djs HOT 5 CLOSED

Hm strange. Are all the necessary ROS nodes running (e.g., map server and including robot_pose_publisher, this is one many people typically forget).

from nav2djs.

Yes, I have all the nodes running and even I can navigate using Rviz. Every time I execute the html example file at the rosbridge_server console I get this:

That is ok, or I should get something else or different?

from nav2djs.

That looks fine. You are running the tutorial map server? i.e., with the Willow map?

Also, is rostopic echo /robot_pose working correctly?

from nav2djs.

I have reached the same issue.

Topic /map also provides data. I can see my map successfully in RViz. The map has quite some unoccupied space on its margins. I'm not sure if the web widget is scaling the map properly?

/move_base is my correct topic name.

I'm using Ubuntu 14.04 with Chrome 36 on client.

Any ideas what could be wrong?

Thank you

There were some issues on the latest version of Chrome preventing rendering, this should now be fixed in the latest ros2djs and nav2djs!
