Hello, I saw that the robot im using has a sonar topic which publishes the sensor message "range".
I have tested the topic with rostopic echo and looked at this link:
http://docs.ros.org/en/api/sensor_msg...
But i cant seem to figure out how the sensor actually works.
What does the sensor return after a callback?
Any help is appreciated, thanks
The message definition gives a relatively clear description of what the message is:
Single range reading from an active ranger that emits energy and reports one range reading that is valid along an arc at the distance measured. This message is not appropriate for laser scanners. See the LaserScan message if you are working with a laser scanner.
Please be more specific if this doesn't help point you to the right answer.

Is the question about how sonar sensors work, or how the data carried by
sensor_msgs/Rangeshould be interpreted?Im asking how to interpret the data
Could you clarify what is unclear?
