Hi, I just wanted to know if there is some example on getting sonar and bumper data from a pioneer3dx using p2os, I can't find anything. I thought it was like getting pose data but now I think it's nothing like that. Can you help me?

It seems like p2os does not offer access to bumper data, but is it possible in any way?

Thanks in advance.

p2os_driver publishes sonar data on the sonar topic. The data is a special data type p2os_driver::SonarArray whose definition you can see in p2os_driver/msg/SonarArray.msg. You may need to enable sonar via the ~use_sonar parameter.

Thank you very much, but what about the bumpers?

It doesn't look like p2os_driver provides bumper data, from what I can see.

So what can I do to access to that data?

I went into p2os_driver/src/p2os.cc and changed false in

n_private.param("use_sonar", use_sonar_, false); to true;

however, rostopic echo /sonar still does not produce ranges. It also doesn't even sound as if the sonar sensors are running. How can I get the sonar working?
