jackal_description Package
===========================
The jackal_description package is the URDF robot description for Jackal UGV.
.. _Source: https://github.com/jackal/jackal
Overview
---------
This package provides a `URDF <http://wiki.ros.org/urdf>`_ model of Jackal. For an example launchfile to use in visualizing this model, see `jacakl_viz <http://wiki.ros.org/jackal_viz>`_.

Accessories
------------
Jackal has a suite of optional payloads called accessories. These payloads can be enabled and placed on Jackal using environment variables specified at the time the `xacro <http://wiki.ros.org/xacro>`_ is rendered to URDF. Available accessory vars are:

Accessory Fenders
------------------
Jackal can optionally include extended front and rear fenders for mounting accessories. Normally these are used
for mounting dedicated front and rear laser scanners, but may be used for mounting other payloads.

.. |with_fender| image:: images/jackal_front_fender.png
:width: 45%
If your Jackal includes fenders on the front and/or rear, make sure to set ``JACKAL_FRONT_ACCESSORY_FENDER`` and/or
``JACKAL_REAR_ACCESSORY_FENDER`` as necessary.
Configurations
----------------
As an alternative to individually specifying each accessory, some fixed configurations are provided in the package. These can be specified using the ``config arg to description.launch``, and are intended especially as a convenience for simulation launch.
==================================== ====================================================
Config: Description:
==================================== ====================================================
base Base Jackal, includes IMU and GPS
front_laser Include front-facing LMS1xx LIDAR.
front_bumblebee2 Includes front-facing Pointgrey Bumblebee2
front_flea3 Includes front-facing Pointgrey Flea3
==================================== ====================================================
