\section General

This is a collection of algorithms, simulations, and tools 
developed by the Robotics Group for Self-Organization of Control
(http://robot.informatik.uni-leipzig.de).\n
It consists of the following directories (click for details):
  - \ref selforg : controllers together with a small framework for using them,
	developed in the robotic group of Leipzig university
	yielding at self-organized behavior for various kinds of machines. 
  - \ref ode_robots : physics simulator based on ODE 
	(Open Dynamics Engine, see http://www.ode.org). 
	This includes such as robots, obstacles, utilities, 
         stuff for visualization with OSG 
        (OpenSceneGraph, see http://www.openscenegraph.org) and so on.
  - \ref guilogger : application that coordinates multiple gnuplot 
	windows and allows for an interactive display of data that is sent per pipe from another   - \ref matrixvix : application for interactive display of changing matrix and vector data
  - \ref configurator : a library implementing a GUI to change the parameters interactively
        which is otherwise done on the console
  - \ref ga_tools : genetic algorithms framework that can be used to together with 
        ode_robots or for independent simulations (not well maintained)
program 
  - \ref opende : directory with a snapshot of the open dynamics engine (release 0.11.1)
                  renamed to ode-dbl in order to avoid conflicts with packaged single
                  precision versions. It contains the capsule-box collision bugfix 
                  which is upstream (in svn)
                  (please follow the link for installation hints)

\section Inst Installation \& Startup

You have two different ways to get the simulator to work. 
- A) Install a package for your distribution.
     This is the quick 'n' easy way if you have root permissions,  see \ref InstA.
- B) Download the source tar ball and compile the simulator yourself, see \ref InstB

\subsection InstA Way A: Package installation
\subsubsection Ubuntu
  A package repository is hosted at
  https://launchpad.net/~georg-martius/+archive/lpzrobots \n
  Do on a terminal (or read the link: "read about installing" on that page):
\verbatim
sudo add-apt-repository ppa:georg-martius/lpzrobots
sudo apt-get update
\endverbatim
Then you can install <tt>lpzrobots</tt> as any other package do:
\verbatim
sudo apt-get install guilogger lpzrobots-oderobots
\endverbatim
This will automatically install all other dependencies.

That's it!

Now you can copy the sample simulations from
  <tt>/usr/share/lpzrobots/</tt> to your home directory and 
  continue reading in section \ref RunExample.

\subsubsection Other debian based systems (deb)
There is an install makefile located here: 
http://robot.informatik.uni-leipzig.de/software/packages/deb/install_deb_source.makefile .
Save it on you disk in an empty directory and run on the console
\verbatim
su -c apt-get install make
make -f install_deb_source.makefile
\endverbatim
That will download the newest packages, compile them and install it.
If something fails you can also redo parts of the process, see "make -f install_deb_source.makefile help".

The packages are: guilogger, matrixviz, ode-dbl, lpzrobots-selforg, and lpzrobots-oderobots
You can uninstall them later using the package manager (apt-get or synaptics)

\subsubsection Alternatively: Creating your own packages
You can do it step by step as follows:
Download all files from http://robot.informatik.uni-leipzig.de/software/packages/deb/current/ \n
Then do
\verbatim
# here you should not be root
 dpkg-source -x guilogger-0.*.dsc
 cd guilogger-0.* 
 dpkg-buildpackage -rfakeroot -b -uc
 cd ../
# become root (e.g. with su or sudo -s)
 dpkg -i guilogger-0.*.deb
\endverbatim
This you have to repeat for each package (e.g. replace guilogger by ode-dbl, lpzrobots-selforg, and lpzrobots-oderobots)

\subsection InstB Way B: Installation from source
\subsubsection Linux
 Check the <tt>Dependencies</tt> file for required packages.

\subsubsection MAC
 We recommend to install the ODE and OSG via macports (http://www.macports.org)
 (after installation of macports type on a console 
 <tt>sudo port install osg OpenSceneGraph</tt>) and see the <tt>Dependencies</tt> file.
 We will update the mac-related install procedures soon.

\subsubsection Instructions

- Download the source tar ball from 
  http://robot.informatik.uni-leipzig.de/software/current .
- Unpack file (<tt>tar -xvzf lpzrobots*.tar</tt>).
- Change into <tt> lpzrobots </tt> directory
- Call <tt> make help</tt> to get a help display and continue with
  <b><tt> make all</tt></b>. This will do everything. The first time you call it
  it will configure your build (you can reconfigure later with make conf).
  The following modules are compiled:
	- \ref matrixviz (not strictly necessary, only for displaying neuronal network parameters online) 
	- \ref guilogger (not strictly necessary, only for displaying parameters online (recommended)) 
	- \ref configurator library (not strictly necessary, only for changing parameters conveniently)
    	- Please note, that the make call will not fail if either of them failed to compile, because they are optional. You can type <tt> make guilogger </tt> and <tt> make matrixviz </tt> to compile them separately.
	- \ref selforg
	- \ref opende (our ode version with double precision) (required)
	- \ref ode_robots
	- \ref ga_tools 
  - if you do it step by step as display with <tt>make help</tt> 
     you need to use <tt>sudo make xxxx</tt> if the installation is into a system directory. (make all will do use it automatically if required). Note that the <tt>PATH</tt> variable needs to contain the PREFIX<tt>/bin</tt> (as checked by the configuration process). If you have multiple lpzrobots installations make sure the prefix for the current lpzrobots comes first in the <tt>PATH</tt> variable

- Now you are done with the installation and you can try a sample simulation see next section.

\subsection RunExample Run example Simulations
- Simulations are located in <tt>ode_robots/simulations/</tt>,<tt>ode_robots/examples/</tt>, and <tt>selforg/simulations/</tt>. This folders you can find in the lpzrobots tar files or if installed on your system under <tt>/usr/share/lpzrobots</tt>or<tt>/usr/local/share/lpzrobots</tt>. In the latter case copy the simulations to your home directory first.
- To start a simulation go into a simulation directory. 
- Call <tt>make</tt> to compile it.
- You can start the simulation by <tt>./start</tt>.
- For example when you want to start the template_sphererobot simulation type:
\verbatim
cd ode_robots/simulations/template_sphererobot
./start 
\endverbatim
- for optimization you can also use <tt>make opt</tt> which produces and <tt>start_opt</tt>. This is recommended to use after testing the code. 
- The following command line options are available 
  (type ./start -h for a full list of options): \n
\verbatim
Usage: ./start [-g [interval]] [-f [interval]] [-r seed] [-x WxH] [-fs]
                 [-pause] [-shadow N] [-noshadow] [-drawboundings] [-simtime [min]] [-threads N]
                 [-odethread] [-osgthread] [-savecfg]
        -g interval     use guilogger (default interval 1)
        -f interval     write logging file (default interval 5)
        -m interval     use matrixviz (default interval 10)
        -s "-disc|ampl|freq val"        use soundMan
        -r seed         random number seed
        -x WxH          * window size of width(W) x height(H) is used (default 640x480)
        -fs             fullscreen mode
        -pause          start in pause mode
        -nographics             start without any graphics
        -noshadow       disables shadows and shaders (same as -shadow 0)
        -shadow [0..5]]         * sets the type of the shadow to be used
                        0: no shadow, 1: ShadowVolume, 2: ShadowTextue, 3: ParallelSplitShadowMap
                        4: SoftShadowMap, 5: ShadowMap (default)
        -shadowsize size        * sets the size of the shadow texture (default 2048)
        -drawboundings  enables the drawing of the bounding shapes of the meshes
        -simtime min    limited simulation time in minutes
        -savecfg        safe the configuration file with the values given by the cmd line
        -threads N      number of threads to use (default is the number of processors)
        -odethread      * if given the ODE runs in its own thread. -> Sensors are delayed by 1
        -osgthread      * if given the OSG runs in its own thread (recommended)
        * this parameter can be set in the configuration file ~/.lpzrobots/ode_robots.cfg
\endverbatim
- On some machine the program crashed right away because of graphic card incompatibilities,
  try: <tt>./start -noshadow</tt>
- Have a look at the console after starting the program, 
  there you will find some further information for the usage of the program.
- E. g. with Ctrl+C (on the terminal) you get a interactive console interface 
  which can be used to modify  parameters on the fly.
- For starting your own simulation see paragraph "How to Start Your Own Simulation" 
  in \ref ode_robots.
- For a well documented examples of a main.cpp of a simulation and a robot .cpp file click 
  the tab "Examples" at the top of this page.
