I want to do the comparison of global planning methods available in navigation stack. When I change global planner of move_base from navfn to carrot_planner I`m getting following error:

Failed to create the base_local_planner/TrajectoryPlannerROS planner, are you sure it is properly registered and that the containing library is built? Exception: MultiLibraryClassLoader: Could not create class of type base_local_planner::TrajectoryPlannerROS

[move_base-2] process has died

In order to change planning method I modified the launch file by including this line

<param name="base_global_planner" value="carrot_planner/CarrotPlanner"/>

Why is this happening?

Precisely what parameter did you change?

Go back a step. Does your launch file work if you don't include that line?

Yes, works like a charm. It also works when i set value to "navfn/NavfnROS" (default planner).

I have the same problem. Works great by setting navfn/NavfnROS but dies when using carrot_planner/CarrotPlanner. I'm using ros-groovy.

I have the same problem. Have you solved it?

Same problem here. Carrot Planner works fine with dwa_local_planner, but I get the same error when trying to use it with base_local_planner.

A) Make sure all your planners are built. B) Try this launch file (add your own map instead of some_package)
