Running Cartographer ROS on a demo bag
======================================

Now that Cartographer and Cartographer's ROS integration are installed, you can
download example bags (e.g. 2D and 3D backpack collections of the
`Deutsches Museum <https://en.wikipedia.org/wiki/Deutsches_Museum>`_) to a
known location, in this case ``~/Downloads``, and use ``roslaunch`` to bring up
the demo.

The launch files will bring up ``roscore`` and ``rviz`` automatically.

.. warning:: When you want to run cartographer_ros, you might need to source your ROS environment by running ``source install_isolated/setup.bash`` first (replace bash with zsh if your shell is zsh)

Deutsches Museum
================

Download and launch the 2D backpack demo:

.. code-block:: bash

    wget -P ~/Downloads https://storage.googleapis.com/cartographer-public-data/bags/backpack_2d/cartographer_paper_deutsches_museum.bag
    roslaunch cartographer_ros demo_backpack_2d.launch bag_filename:=${HOME}/Downloads/cartographer_paper_deutsches_museum.bag

Download and launch the 3D backpack demo:

.. code-block:: bash

    wget -P ~/Downloads https://storage.googleapis.com/cartographer-public-data/bags/backpack_3d/with_intensities/b3-2016-04-05-14-14-00.bag
    roslaunch cartographer_ros demo_backpack_3d.launch bag_filename:=${HOME}/Downloads/b3-2016-04-05-14-14-00.bag

Pure localization
=================

Pure localization uses 2 different bags. The first one is used to generate the map, the second to run pure localization.

Download the 2D bags from the Deutsche Museum:

.. code-block:: bash

    wget -P ~/Downloads https://storage.googleapis.com/cartographer-public-data/bags/backpack_2d/b2-2016-04-05-14-44-52.bag
    wget -P ~/Downloads https://storage.googleapis.com/cartographer-public-data/bags/backpack_2d/b2-2016-04-27-12-31-41.bag

Generate the map (wait until cartographer_offline_node finishes) and then run pure localization:

.. code-block:: bash

    roslaunch cartographer_ros offline_backpack_2d.launch bag_filenames:=${HOME}/Downloads/b2-2016-04-05-14-44-52.bag
    roslaunch cartographer_ros demo_backpack_2d_localization.launch \
       load_state_filename:=${HOME}/Downloads/b2-2016-04-05-14-44-52.bag.pbstream \
       bag_filename:=${HOME}/Downloads/b2-2016-04-27-12-31-41.bag

Download the 3D bags from the Deutsche Museum:

.. code-block:: bash

    wget -P ~/Downloads https://storage.googleapis.com/cartographer-public-data/bags/backpack_3d/b3-2016-04-05-13-54-42.bag
    wget -P ~/Downloads https://storage.googleapis.com/cartographer-public-data/bags/backpack_3d/b3-2016-04-05-15-52-20.bag

Generate the map (wait until cartographer_offline_node finishes) and then run pure localization:

.. code-block:: bash

    roslaunch cartographer_ros offline_backpack_3d.launch bag_filenames:=${HOME}/Downloads/b3-2016-04-05-13-54-42.bag
    roslaunch cartographer_ros demo_backpack_3d_localization.launch \
       load_state_filename:=${HOME}/Downloads/b3-2016-04-05-13-54-42.bag.pbstream \
       bag_filename:=${HOME}/Downloads/b3-2016-04-05-15-52-20.bag

Static landmarks
================

  .. raw:: html

  .. code-block:: bash

    # Download the landmarks example bag.
    wget -P ~/Downloads https://storage.googleapis.com/cartographer-public-data/bags/mir/landmarks_demo_uncalibrated.bag

    # Launch the landmarks demo.
    roslaunch cartographer_mir offline_mir_100_rviz.launch bag_filename:=${HOME}/Downloads/landmarks_demo_uncalibrated.bag

Revo LDS
========

Download and launch an example bag captured from a low-cost Revo Laser Distance Sensor from Neato Robotics vacuum cleaners:

.. code-block:: bash

    wget -P ~/Downloads https://storage.googleapis.com/cartographer-public-data/bags/revo_lds/cartographer_paper_revo_lds.bag
    roslaunch cartographer_ros demo_revo_lds.launch bag_filename:=${HOME}/Downloads/cartographer_paper_revo_lds.bag

PR2
===

Download and launch an example bag captured from a PR2 R&D humanoid robot from Willow Garage:

.. code-block:: bash

    wget -P ~/Downloads https://storage.googleapis.com/cartographer-public-data/bags/pr2/2011-09-15-08-32-46.bag
    roslaunch cartographer_ros demo_pr2.launch bag_filename:=${HOME}/Downloads/2011-09-15-08-32-46.bag

Taurob Tracker
==============

Download and launch an example bag captured from a Taurob Tracker teleoperation robot:

.. code-block:: bash

    wget -P ~/Downloads https://storage.googleapis.com/cartographer-public-data/bags/taurob_tracker/taurob_tracker_simulation.bag
    roslaunch cartographer_ros demo_taurob_tracker.launch bag_filename:=${HOME}/Downloads/taurob_tracker_simulation.bag
