Detailed Description

The CostmapControllerExecution binds a local costmap to the AbstractControllerExecution and uses the nav_core/BaseLocalPlanner class as base plugin interface. This class makes move_base_flex compatible to the old move_base.

Constructor & Destructor Documentation

mbf_costmap_nav::CostmapControllerExecution::CostmapControllerExecution	(	const std::string &	controller_name,
		const mbf_costmap_core::CostmapController::Ptr &	controller_ptr,

Constructor.

Parameters

controller_name	Name of the controller to use.
controller_ptr	Shared pointer to the plugin to use.
vel_pub	Velocity commands publisher.
goal_pub	Goal pose publisher (just vor visualization).
tf_listener_ptr	Shared pointer to a common tf listener.
costmap_ptr	Shared pointer to the local costmap.
config	Current server configuration (dynamic).

privatevirtual

Request plugin for a new velocity command. We override this method so we can lock the local costmap before calling the planner.

Parameters

pose	the current pose of the robot.
velocity	the current velocity of the robot.
cmd_vel	Will be filled with the velocity command to be passed to the robot base.
message	Optional more detailed outcome as a string.

Returns: Result code as described on ExePath action result and plugin's header.
