Detailed Description

If you have another ranging device with different behavior (e.g. a sonar array), please find or create a different message, since applications will make fairly laser-specific assumptions about this data

laserScan is a structured value type usable in QML. It maps directly to the sensor_msgs::msg::LaserScan ROS 2 message type.

Construct a laserScan in QML by assigning a JavaScript object whose keys are its component properties, or by setting those properties individually.
