Pose2DPublisher QML Type

Publishes geometry_msgs::msg::Pose2D messages — Please use the full 3D pose. More...

This type is deprecated since QtRos2.GeometryMsgs Foxy. We strongly advise against using it in new code.

• List of all members, including inherited members

Properties

• theta : double
• x : double
• y : double

Methods

• void publish(pose2D msg)

Detailed Description

In general our recommendation is to use a full 3D representation of everything and for 2D specific applications make the appropriate projections into the plane for their calculations but optimally will preserve the 3D information during processing.

If we have parallel copies of 2D datatypes every UI and other pipeline will end up needing to have dual interfaces to plot everything. And you will end up with not being able to use 3D tools for 2D use cases even if they're completely valid, as you'd have to reimplement it with different inputs and outputs. It's not particularly hard to plot the 2D pose or compute the yaw error for the Pose message and there are already tools and libraries that can do this for you.# This expresses a position and orientation on a 2D manifold.

Pose2DPublisher publishes pose2D values to a ROS 2 topic. Set the topic and node properties, then call publish() to send messages.

Property Documentation

theta : double

The theta field value included in the next publish. Setting this property emits thetaChanged and, when autoPublish is true, requests a publish at the end of the current event-loop iteration.

x : double

The x field value included in the next publish. Setting this property emits xChanged and, when autoPublish is true, requests a publish at the end of the current event-loop iteration.

y : double

The y field value included in the next publish. Setting this property emits yChanged and, when autoPublish is true, requests a publish at the end of the current event-loop iteration.

Method Documentation

void publish(pose2D msg)

Publishes pose2D msg to the ROS 2 topic set by the topic property. Does nothing if the publisher is not connected.
