yes, was problem of the route, now is working but I have now another problem with the dimension of the model:<br><br>the model made in sketchup have the same dimension that the model from example urdf_tutorial, I mean length 0.6 meters and radios 0.2 meters.<br>
<br>the base link:<br>  &lt;link name=&quot;base_link&quot;&gt;<br>    &lt;visual&gt;<br>      &lt;geometry&gt;<br>        &lt;cylinder length=&quot;0.6&quot; radius=&quot;0.2&quot;/&gt;<br>      &lt;/geometry&gt;<br>      &lt;material name=&quot;blue&quot;&gt;<br>
        &lt;color rgba=&quot;0 0 .8 1&quot;/&gt;<br>      &lt;/material&gt;<br>    &lt;/visual&gt;<br>  &lt;/link&gt;<br><br>but in rviz I see a big cylinder much more bigger than the base_link.......<br><br><a href="http://dl.dropbox.com/u/2950889/tube.png">http://dl.dropbox.com/u/2950889/tube.png</a><br>
