There isn&#39;t currently a way to poll messages (though it&#39;s on our roadmap: <meta http-equiv="content-type" content="text/html; charset=utf-8"><a href="http://www.ros.org/wiki/ROS/Roadmap">http://www.ros.org/wiki/ROS/Roadmap</a>).  If you just want to throttle it to 5ms though, you can use the throttle node in topic_tools: <meta http-equiv="content-type" content="text/html; charset=utf-8"><a href="http://www.ros.org/wiki/topic_tools/throttle">http://www.ros.org/wiki/topic_tools/throttle</a><div>

Hi, all<br>
<br>
Is there a way to subscribe newest msg (not srv) at any prefered time? (like client node)<br>
I would like to subscribe a specific message by every 5ms.<br>
I know it is possible to realize such polling with srv, but Service-Client node allows only srv not msg.<br>
How can I realize such polling with msg?<br>
<br>
Thanks in advance,<br>
<br>
Keisuke<br>
