Member Data Documentation

◆ allow_skip

bool mrpt::nav::TWaypoint::allow_skip

[Default=true] Whether it is allowed to the navigator to proceed to a more advanced waypoint in the sequence if it determines that it is easier to skip this one (e.g.

it seems blocked by dynamic obstacles). This value is ignored for the last waypoint in a sequence, since it is always considered to be the ultimate goal and hence not subject to be skipped.

◆ allowed_distance

double mrpt::nav::TWaypoint::allowed_distance

[Must be set by the user] How close should the robot get to this waypoint for it to be considered reached.

Definition at line 37 of file TWaypoint.h.

Referenced by getAsText(), isValid(), and mrpt::nav::CWaypointsNavigator::waypoints_navigationStep().

◆ INVALID_NUM

const double TWaypoint::INVALID_NUM = std::numeric_limits<double>::max()

static

The default value of fields (used to detect non-set values)

Definition at line 58 of file TWaypoint.h.

Referenced by mrpt::nav::TWaypointSequence::getAsOpenglVisualization(), mrpt::nav::TWaypointStatusSequence::getAsOpenglVisualization(), getAsText(), isValid(), mrpt::nav::TWaypointSequence::load(), and mrpt::nav::CWaypointsNavigator::waypoints_navigationStep().

◆ speed_ratio

double mrpt::nav::TWaypoint::speed_ratio

(Default=1.0) Desired robot speed at the target, as a ratio of the full robot speed.

That is: speed_ratio=1 means that the user wants the robot to navigate to the target and smoothly continue to the next one when reached. speed_ratio=0 on the other hand means that the robot should approach this waypoint slowing down and end up totally stopped.

◆ target

mrpt::math::TPoint2D mrpt::nav::TWaypoint::target

[Must be set by the user] Coordinates of desired target location (world/global coordinates).

◆ target_frame_id

std::string mrpt::nav::TWaypoint::target_frame_id

(Default="map") Frame ID in which target is given. Optional, use only for submapping applications.

Definition at line 35 of file TWaypoint.h.

Referenced by mrpt::nav::CWaypointsNavigator::waypoints_navigationStep().

◆ target_heading

double mrpt::nav::TWaypoint::target_heading

[Default=any heading] Optionally, set to the desired orientation [radians] of the robot at this waypoint.

Some navigator implementations may ignore this preferred heading anyway, read the docs of each implementation to find it out.
