\chapter{SimSpark Simulation Server}
\label{chServer}

The simulation is generated by the SimSpark Soccer Simulation Server. Agents can enter
the simulation by communicating with the soccer server using tcp sockets and a
hierarchical parentheses based communication protocol (think of LISP). The simulation maintains a
physically realistic (although at the moment noiseless) world, existing of a
soccer field and soccer(ro)bots. One agent program represents one soccer robot in the
simulation.

As of the World Championship of 2007 the simulation can only reliably run two agents per
team and still had some hiccups in the form of physics errors causing exploding body part.
But we are confident that these will be resolved in the near future.

\section{The Soccer Field}

Currently (RoboCup 2007) the soccer field is a rectangular field of 50 meters by 32 meters
length and width. In each corner there resides a flag and on each side there are two goal
posts. The size of the field is subjected to change and probably won't stay the same for
very long. Luckily the server notifies the agent of the size of the field at the initiation
of communication.


\section{The Soccerbot}

The soccerbot is a humanoid robot, loosely based on Fujitsu's HOAP-2 robot.
