Member Function Documentation

bool eband_local_planner::EBandPlannerROS::computeVelocityCommands ( geometry_msgs::Twist &  cmd_vel) [virtual]

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

Parameters:
cmd_velWill be filled with the velocity command to be passed to the robot base
Returns:
True if a valid trajectory was found, false otherwise

Implements nav_core::BaseLocalPlanner.

Definition at line 198 of file eband_local_planner_ros.cpp.

void eband_local_planner::EBandPlannerROS::initialize ( std::string  name,
tf::TransformListener tf,
costmap_2d::Costmap2DROS costmap_ros 
) [virtual]

Initializes the ros wrapper.

Parameters:
nameThe name to give this instance of the trajectory planner
tfA pointer to a transform listener
costmapThe cost map to use for assigning costs to trajectories

Implements nav_core::BaseLocalPlanner.

Definition at line 68 of file eband_local_planner_ros.cpp.

Check if the goal pose has been achieved.

Returns:
True if achieved, false otherwise

void eband_local_planner::EBandPlannerROS::odomCallback ( const nav_msgs::Odometry::ConstPtr &  msg) [private]

Odometry-Callback: function is called whenever a new odometry msg is published on that topic.

Parameters:
Pointerto the received message

Definition at line 385 of file eband_local_planner_ros.cpp.

bool eband_local_planner::EBandPlannerROS::setPlan ( const std::vector< geometry_msgs::PoseStamped > &  orig_global_plan) [virtual]

Set the plan that the controller is following; also reset eband-planner.

Parameters:
orig_global_planThe plan to pass to the controller
Returns:
True if the plan was updated successfully, false otherwise
