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

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

See also LaserScanSubscriber and laserScan.

Property Documentation

angleIncrement : real

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

angleMax : real

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

angleMin : real

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

header : header

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

intensities : list<real>

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

rangeMax : real

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

rangeMin : real

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

ranges : list<real>

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

scanTime : real

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

timeIncrement : real

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