I've been trying to get ROS and Care-O-Bot installed and running for some time now. I can never get Gazebo to initialize properly. I'm using Ubuntu 10.04, and Fuerte

I start with the instructions here:

Then these:

I can get through all of the ROS tutorials, so I believe that everything has been done correctly with respect to ROS, but when I run cob_bringup_sim Gazebo fails with the following error:

Error [Plugin.hh:100] Failed to load plugin -1: -1: cannot open shared object file: No such file or directory
Warning [] Gazebo SDF has no gazebo element
Warning [] parser for sdf version 1.0 failed, trying to parse as old deprecated format
Segmentation fault

For reference, here is the Gazebo cmd that cob_bringup_sim generates, running this line solo creates the same error:
/opt/ros/fuerte/stacks/simulator_gazebo/gazebo/scripts/gazebo -s -1 /opt/ros/fuerte/stacks/cob_environments/cob_gazebo_worlds/common/worlds/ __name:=gazebo __log:=/home/nathan/.ros/log/58188a6e-bee5-11e1-bd07-f46d0412dc71/gazebo-2.log

No log file is generated, and I can only assume that Gazebo never even attempts to load.

It seems to stem from the combination of Fuerte and COB. As soon as I rolled back to Electric, everything started working. Not sure if something has changed in the format of the simulation files for Fuerte that makes the current COB code not work, but for now I'm just sticking to Electric.

There is an issue with the your launch file

gazebo -s <plugin_name>

So in your case gazebo tries to load a plugin called -1.

I believe you wanted to make inital position for the robot and you meant:

gazebo -x -1 <world_file>

Check your launch file for misspelling.
