Hi, I'm using amcl with a defaut topic scan and it keep telling me: "No laser scan received (and thus no pose updates have been published) for XXX seconds"

I have double check my topic scan and made an initial pose with RViz. Thanks for your answers.

Okay, the only question I see here is: "What is the amcl default topic?".

Answering this: The default topic of amcl is scan (see the ROS wikipage on amcl or the sourcecode for this).

If this is not the question, please be more specific, add a real question and the launch/config files. Otherwise, we cannot help at all.

Thanks for your answer. It's "scan" indeed. I have check if the node amcl correctly subscribe to scan and it does, so the second part of my question is why it keep telling me this message. During this morning, I have done some tests and it seems that this answer is a false one and the problem might be link to the TF tree.
