I know you can run gmapping node and specify an inverted laser:<br><pre class="prettyprint ">    &lt;node pkg=&quot;gmapping&quot; type=&quot;slam_gmapping&quot; name=&quot;slam_gmapping&quot; respawn=&quot;false&quot; output=&quot;screen&quot; &gt;<br>
        &lt;param name=&quot;inverted_laser&quot; value=&quot;true&quot; /&gt;<br>    &lt;/node&gt;<br></pre><br>Anton<br><br><div class="gmail_quote">On Tue, Apr 13, 2010 at 5:51 AM, Jeff Rousseau <span dir="ltr">&lt;<a href="mailto:jrousseau@aptima.com">jrousseau@aptima.com</a>&gt;</span> wrote:<br>

<br>
Is there an easy way to invert the laser scan data of a hokuyo like<br>
there is with a SICK?  The sicktoolbox_wrapper node has an &quot;inverted&quot;<br>
parameter, but I didn&#39;t see a similar option on the hokuyo wiki page.<br>
<br>
I have a hokuyo mounted upside down and am not sure how to compensate<br>
for that (for use in the nav stack)<br>
