class SimpleProgressChecker : public nav2_core::ProgressChecker 

This plugin is used to check the position of the robot to make sure that it is actually progressing towards a goal.

Subclassed by nav2_controller::PoseProgressChecker

Public Functions

Protected Functions

bool isRobotMovedEnough(const geometry_msgs::msg::Pose2D &pose)

Calculates robots movement from baseline pose.

Parameters:: pose – Current pose of the robot
Returns:: true, if movement is greater than radius_, or false

void resetBaselinePose(const geometry_msgs::msg::Pose2D &pose)

Resets baseline pose with the current pose of the robot.

Parameters:: pose – Current pose of the robot

rcl_interfaces::msg::SetParametersResult dynamicParametersCallback(std::vector<rclcpp::Parameter> parameters)

Callback executed when a paramter change is detected.

Parameters:: parameters – list of changed parameters
