Detailed Description

This message is not appropriate for laser scanners. See the LaserScan message if you are working with a laser scanner.

This message also can represent a fixed-distance (binary) ranger. This sensor will have min_range===max_range===distance of detection. These sensors follow REP 117 and will output -Inf if the object is detected and +Inf if the object is outside of the detection range.

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

See also RangeSubscriber and range.

Property Documentation

fieldOfView : real

The fieldOfView field value included in the next publish. Setting this property emits fieldOfViewChanged 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.

maxRange : real

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

minRange : real

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

radiationType : uint8_t

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

range : real

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

variance : real

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