-==== ARGoS + Buzz quick start ====
-=== ARGoS ===
-[[http://www.argos-sim.info|ARGoS]] is a fast multi-robot simulator that can interoperate with Buzz.
-To install ARGoS, go to http://www.argos-sim.info/core.php and install a binary package. To get started with ARGoS, refer to the [[https://github.com/ilpincy/argos3-examples|examples]].
-=== Buzz ===
-Compile and install Buzz following the instructions reported in the [[https://github.com/MISTLab/Buzz|GitHub page]]. Make sure to compile Buzz **after** having installed ARGoS, so the compilation scripts will also compile the ARGoS integration code.
-=== ARGoS + Buzz ===
-== Integration: Basic information ==
-The Buzz integration library for ARGoS is composed of two elements:
-  - A set of ARGoS controllers. At the moment, available controllers include one for the [[http://www.swarmanoid.org/swarmanoid_hardware.php.html|foot-bot]] (a wheeled robot) and one for the [[http://pleiades.ca|Spiri]] (a commercial quad-rotor). More can be added easily by subclassing ''CBuzzController'', defined in ''$PREFIX/include/buzz/argos/buzz_controller.h''. ''$PREFIX'' depends on your system and is usually ''/usr'' or ''/usr/local''.
-  - A special definition of ARGoS' QtOpenGL user functions, which allow Buzz scripts to draw in the OpenGL visualization of ARGoS. With these, a developer can write debugging information on top of each robot.
-To have ARGoS find the Buzz integration library in case you installed it in a non-default location, set the environment variable ''ARGOS_PLUGIN_PATH''. This variable is a '':''-separated list of directories in which ARGoS looks for libraries before launching an experiment. For instance:
-<code bash>
-$ export ARGOS_PLUGIN_PATH=/opt/lib/buzz
-</code>
-If you installed Buzz without specifying a custom installation prefix (e.g., using only ''cmake ../src; make; make install''), you don't need to set ''ARGOS_PLUGIN_PATH''.
-== Defining an ARGoS experiment file ==
-To use ARGoS and Buzz together, define your ''.argos'' experiment file as usual.
-However, instead of a custom controller, in the ''<controllers>'' section use ''<buzz_controller_footbot>'' or ''<buzz_controller_spiri>'' (or both!), depending on the robots you intend to use. For example, if you want to use both controllers, write something similar to this:
-<code xml>
-  <controllers>
-    <buzz_controller_footbot id="bcf">
-      <actuators>
-        <differential_steering implementation="default" />
-        <leds                  implementation="default" medium="leds" />
-        <range_and_bearing implementation="default" />
-      </actuators>
-      <sensors>
-        <range_and_bearing implementation="medium" medium="rab" show_rays="true" noise_std_dev="0" />
-      </sensors>
-      <params bytecode_file="myscript.bo" debug_file="myscript.bdbg" />
-    </buzz_controller_footbot>
-    <buzz_controller_spiri id="bcs">
-      <actuators>
-        <quadrotor_position implementation="default" />
-        <range_and_bearing  implementation="default" />
-      </actuators>
-      <sensors>
-        <range_and_bearing implementation="medium" medium="rab" show_rays="false" />
-        <positioning       implementation="default" />
-      </sensors>
-      <params bytecode_file="myscript.bo" debug_file="myscript.bdbg" />
-    </buzz_controller_spiri>
-  </controllers>
-</code>
-To activate drawing, use ''buzz_qt'' to indicate that you want to use the Buzz QtOpenGL user functions:
-<code xml>
-  <visualization>
-    <qt-opengl>
-      <user_functions label="buzz_qt" />
-    </qt-opengl>
-  </visualization>
-</code>
-You can launch ARGoS as usual, with the command:
-<code bash>
-$ argos3 -c myexperiment.argos
-</code>
-Make sure the paths of the Buzz bytecode file (e.g., ''myscript.bo'' and ''myscript.bdbg'' in the above example) are set correctly.
