Member Function Documentation

virtual bool nav_core::BaseLocalPlanner::computeVelocityCommands

(

geometry_msgs::Twist &

cmd_vel

)

[pure virtual]

Given the current position, orientation, and velocity of the robot, compute velocity commands to send to the base.

Parameters:

cmd_vel

Will be filled with the velocity command to be passed to the robot base

Returns:

True if a valid velocity command was found, false otherwise

virtual void nav_core::BaseLocalPlanner::initialize	(	std::string	name,
		tf::TransformListener *	tf,
		costmap_2d::Costmap2DROS *	costmap_ros
	)		[pure virtual]

Constructs the local planner.

Parameters:

name	The name to give this instance of the local planner
tf	A pointer to a transform listener
costmap	The cost map to use for assigning costs to local plans

virtual bool nav_core::BaseLocalPlanner::isGoalReached

(

)

[pure virtual]

Check if the goal pose has been achieved by the local planner.

Returns:

True if achieved, false otherwise

virtual bool nav_core::BaseLocalPlanner::setPlan

(

const std::vector< geometry_msgs::PoseStamped > &

plan

)

[pure virtual]

Set the plan that the local planner is following.

Parameters:

orig_global_plan

The plan to pass to the local planner

Returns:

True if the plan was updated successfully, false otherwise
