Hi Konrad,
I think I might have an answer now. Could you please follow these two
steps and let me know if things work for you:
(1) Add the following lines to your urdf
<link name="world">
<inertial>
<mass value="0.05" />
<origin xyz="-0.0 0.0 -10.0" />
<inertia ixx="1.0" ixy="0.0" ixz="0.0"
iyy="1.0" iyz="0.0"
izz="1.0" />
</inertial>
<collision>
<origin xyz="0 0 0.15" rpy="0 0 0" />
<geometry>
<box size="0.4 0.4 0.3" />
</geometry>
</collision>
</link>
<joint name="base_joint" type="fixed">
<parent link="world"/>
<child link="base_link"/>
</joint>
This anchors your robot in the world with a dummy fixed link.
(2) Apply the attached patch to a cturtle version of the
motion_planners stack directory. (I am assuming you are working with
cturtle).
Try again with these changes and let me know - if they work for you, I
will push them out into cturtle. For your reference, I have also
attached a tarred version of the planning files that I used to
configure the planner for your robot. Some of these issues are
currently fixed in trunk but it might take us a while to push out a
release from trunk into cturtle, hence the patch.
Regards,
Sachin
