Hi all<br><br>I am trying to run boxturtle&#39;s collision_map_test.launch (collision_environment/collision_map/) and getting type errors and hanging,<br><br> [ INFO] 5.397000000: Maintaining occlusion map in frame &#39;base_link&#39;, with origin at (1.100000, 0.000000, 0.000000) and dimension (1.000000, 1.500000, 2.000000), resolution of 0.020000; sensor is in frame &#39;&#39;, fixed fame is &#39;base_link&#39;.<br>
[ WARN] 5.407000000: Self see links need to be an array<br>[ WARN] 5.425000000: No robot links will be checked for self mask<br>[ WARN] 5.444000000: No links specified for self filtering.<br> <br>(nothing happens afterwards...)<br>
<br>There&#39;s something simple going wrong, but I can&#39;t figure out how to pass an array as a parameter in xml for launch file to fix it? Newbie xml user I guess, but I also can&#39;t find it through searching. This test file isn&#39;t correct and the other launch file (collision_map.launch) has a broken link? <br>
<br>ERROR: cannot launch node of type [collision_map/collision_map_buffer_node]: Cannot locate node of type [collision_map_buffer_node] in package [collision_map]<br><br>despite it exisiting in the same folder.<br>I&#39;m not sure how I haven&#39;t seen this while using the move_arm tutorials...<br>
<br>Any Ideas/similar experiences?<br><br>Ben<br><br>
