Point cloud and sonar
hi, i read this tutorial link text but i don't understand this lines:
ros::Subscriber sub1 = n.subscribe("sonarBearing", 100, bearingCB); ros::Subscriber sub2 = n.subscribe("sonarBinsArr", 100, binsArrCB);
can you explain it to me please?

The Subscriber keeps to listen the topic which have been published. So, in this example, the subscriber sub1
keeps subscribe the topic sonarBearing
, 100 is the queue size and the bearingCB
is the name of callback function.
Have a look of this tutorial, I think it could help you to realize.
