I am trying to run a LiDar taken from the Neato XV-11 vacuum cleaner on ROS nad amd using RVIZ to visualize the data coming from the sensor. However, I ran into the problem that RVIZ was not receiving and MAP data to display. I consulted the site and As per the video tutorial under map, I found that I did not have any topics being displayed. I tried to enter the topic manually but not RVIZ will not initialize and I am receiving the following error.

[ERROR] [1338754771.604753719]: Caught exception while loading: Character [ ] at element [3] is not valid in Graph Resource Name [map (nav_msgs/OccupancyGrid)]. Valid characters are a-z, A-Z, 0-9, / and _.

Kindly suggest what when wrong and what can be done regarding the same.

Seems to me you placed a space in map (nav_msgs/OccupancyGrid) which is not valid.

Remove that space in ~/.rviz/display_config or ~/.rviz/config and start rviz.

Thanx, but where do I change it? It occured when i tried to manually change the topics in RVIZ, now even the RVIZ windo won't open. I tired looking in the config file in my rviz folder but could not find where the change was made by RVIZ. Kindly help.

Open both mentioned files and search for your buggy string "map (nav_msgs/OccupancyGrid)" or parts of it. And use comments on answers :)

Thanx. But I cannot open the file. I don't know where it is and I am having a hard time finding it. I tried to open the file through the cmd window but it keeps telling me a bunch of errors. I tried the open, edit and even the start command. None of them open the file that I want. Any suggestion?

Umm.. the tilde ~ in linux paths is used to represent the users home directory. type cd ~/.rviz and then ls -- Guess #2: the directory for the new rviz in fuerte is ~/.rviz_qt
