velocityStamped QML Value Type
This expresses the timestamped velocity vector of a frame 'body_frame_id' in the reference frame 'reference_frame_id' expressed from arbitrary observation frame 'header.frame_id'. More...
| Import Statement: | import QtRos2.GeometryMsgs |
| Status: | Experimental Extension |
Properties
- bodyFrameId : string
- header : header
- referenceFrameId : string
- velocity : twist
Detailed Description
- If the 'body_frame_id' and 'header.frame_id' are identical, the velocity is observed and defined in the local coordinates system of the body which is the usual use-case in mobile robotics and is also known as a body twist.
velocityStamped is a structured value type usable in QML. It maps directly to the geometry_msgs::msg::VelocityStamped ROS 2 message type.
Construct a velocityStamped in QML by assigning a JavaScript object whose keys are its component properties, or by setting those properties individually.
