Error loading <rosparam> tag

Hey everybody,

I have a problem with bringing up the turtlebot (roomba base). When I run roslaunch turtlebot_bringup minimal.launch I get the error:

error loading <rosparam> tag: 'param' attribute must be set for non-dictionary values XML is <rosparam command="load" file="$find turtlebot_bringup)/param/$(arg base)/diagnostics.yaml"/>.

What does this mean and what should I do?

Kind regards

This looks like a typo in one of the launch files; you should probably report it as a bug.

Could you explain how did you start the robot? For example, how you set the environment variables.

From limited amount of info I can only assume the launch file in use was turtlebot_bringup/launch/includes/robot.launch.xml or similar. Then in that linked file there doesn't seem to be an error, while in your code snippet the following is broken (need ( before find)).

file="$find turtlebot_bringup)/param/$(arg base)/diagnostics.yaml"
