+----
+== 競技エリア ==
+=== フィールドレイアウト ===
+The competition area for the main challenges consists of a \SI{5 x 5}{\metre}
+area divided in square zones of \SI{1 x 1}{\metre}. Additional challenges that
+are not counting towards the scoring of the competition are carried out on
+a \SI{7 x 8}{\metre} field instead (corresponding to halve the field of the
+regular \ac{RCLL} field).
+
+\todo{add picture of field with zone names}
+
+The entire area belongs to a single team. The bottom left-most
+\SI{1 x 3}{\metre} area is called the insertion zone, It does not need to have
+partial walls around it and provides the starting positions for up to three
+robots.
+
+\subsection{Mockup Machines}\label{sec:machines}
+In case no real \ac{MPS} stations are available, replications
+(so called \emph{mockup machines}) may be used, that do not need to
+physically perform the respective production steps. Instead, that work may
+be carried out by a human supervisor (see \refsec{sec:operators}).
+The minimum requirements for a mockup machine are specified in the following.
+
+Mockup machines are required to have the same box-like base-shape as specified
+in the RCLL rulebook \todo{Link to rulebook}.
+\todo{height of the box is not specified in rulebook, only the height until
+the conveyor belt}.
+On top of the box a model of the conveyor belt has to be mounted, see
+\todo{link to mockup model file and rulebook}.
+On stations replicating a \ac{CS} a shelf as to be additionally mounted on the
+front right side of the box, see
+\todo{link to mockup model file and rulebook}.
+On stations replicating a \ac{RS} either a shelf may be mounted as well,
+or a model of the slide, which may be placed anywhere on the front right side
+of the box, such that it is accessible from the front.
+\todo{link to mockup model file and rulebook}.
+
+The building materials for the models must be opaque, but may have any color.
+
+In order to compete in all main challenges, a minimum number of 3 mockup
+machines are required. On higher difficulty some challenges may require
+4 mockup stations and some secondary challenges require 7 stations.
+
+\subsection{Remote Setup}
+In case a competition is carried out remotely, a proper local setup has to
+be established and approved by the organizational committee
+\todo{or is this TC responsibility?!}.
+Requirements include a proper camera setup that covers the field sufficiently,
+such that external viewers can verify the integrity of each challenges,
+as well as an approval for every mockup machine and robot that is used.
+\todo{verify correct size specs for field, robots, mockup machines}
+
+\section{Game Play}
+\subsection{Competition Scope}
+\todo{X time slots of 10 minute setup time per team, followed by up to 20
+        minutes of game time. Each slot can be used to solve
+at most one challenge, a team can decide to fail a challenge and use another
+slot to improve.
+A team can use a single slot to try a challenge multiple times (with the same
+field layout) once a challenge counts, it cannot be attempted again
+(unless difficulty is increased).}
+
+All challenges (unless stated otherwise) are conducted while measuring
+the execution time. The execution time is measured by the RefBox.
+The fastest team in any challenge gains additional points.
+
+\subsection{Changes compared to the Main Competition}
+The tasks covered in the various challenges mostly obey the regular rules
+for the \ac{RCLL}. However, some aspects are altered to simplify the setup.
+The changes are not affecting existing machine communication and processing
+steps, such that the challenges can be carried out on real machines as well as
+on mockup versions obeying the requirements outlined in \refsec{sec:machines}.
+
+\paragraph{Product Delivery}
+The delivery procedure for finished products is altered compared to the
+\ac{RCLL} rule set. In order to reduce the amount of machines required
+for participation, Deliveries are made by bringing the finished product
+to the insertion zone and dropping it there.
+
+\paragraph{Ring Payments}
+Easing the setup of mockup machines, it is not required to have a slide
+on ring stations. Instead, a shelf may be used to place payments at the
+corresponding station.
+
+\paragraph{Ring Color Assignment}
+The cost for mounting each ring color are fixed, the assignment of ring colors
+is semi-fixed as teams can choose between two different options for each
+challenge (\texttt{option1} or \texttt{option2} according to
+\reftab{tab:ring-costs}).
+\todo{make this configurable in the RefBox}
+

+\paragraph{Materials}\label{sec:materials}
+The available material that can be used per challenge is restricted
+(unless stated otherwise) per machine according to the information in
+\reftab{tab:materials}.

+   \ac{RS} & 4 rings of each assigned color (8 in total)  \\
+  \end{tabularx}
+ \caption{Materials}
+ \label{tab:materials}
+\end{table}
+\todo{is it actually 4 colors per ring station slot?}
+
+\paragraph{Orders}
+Unless specified otherwise, orders that have to be fulfilled in challenges
+are entered through the web shop \todo{link web shop} by any member of the
+competing team.
+
+In challenges where only one \ac{RS} is present, teams are responsible to
+order products which can be assembled using the available stations only.
+
+\subsection{Field Operators}\label{sec:operators}
+In challenges where mockup machines are used, the actual assembly stps have
+to be performed by human supervisors. Whenever a machine is instructed,
+the RefBox operator announces the required interaction. One field operator may
+proceed to enter the field in order to perform the interaction. Afterwards the
+field has to be left immediately.
+The usual rules for replenishing resources (respecting the limited materials
+\refsec{sec:materials}) apply.
+
+\todo{maintenance rules}
+
+\subsection{Available Challenges for the Primary Competition}
+Challenges have different types and variations (difficulty levels).
+The overall score of the competition is calculated by summing up the score
+in the highest difficulty achieved in each of the challenge types.
+The challenge types of the competition are described in
+\refsec{sec:challenge-navigation}-\ref{sec:challenge-markerless}
+
+The RefBox is used to log the scores and data for each challenge.
+Once the competition is finished, $5$ bonus points are awarded each time a
+team solved a challenge on a difficulty in the shortest amount of time.
+\todo{implement challenges in refbox, provide tool to evaluate results}
+
+\subsubsection{Navigation Challenge}\label{sec:challenge-navigation}
+Basic navigation task with known obstacles.\\
+\textbf{Task:} Drive three routes, each starting and ending in the insertion
+zone while covering a given set of target positions. At each target position
+the robot has to stand still (no moving or rotating) for at least 1 second. \\
+Variations of this challenge depend
+on the number of
+available machines (see \reftab{tab:challenge-navigation}).
+Multiple robots may be used to simultaneously cover different routes.
+Partial points may be awarded in case only a subset of routes got covered.

+\subsubsection{Grasping Challenge}\label{sec:challenge-grasping}
+Simple grasping task.
+Each Machine has a base at output.
+Robots start at cell in front of a machine output.\\
+\textbf{Task:} A robot brings a base from one machine's output back to it's
+input. A human supervisor places it back to the output. Repeat until all
+products were placed at the respective machines input 3 times and all robots
+returned to their starting positions. \\
+\todo{improve description}
+Variations differ by number of machines, see
+\reftab{tab:challenge-grasping}. The $i$-th repetition is considered to be
+successful, once all bases were placed at the respective machine input
+at least $i$ times.

+\subsubsection{Product Challenges}\label{sec:challenge-cx}
+This section covers four types of challenges, instead of just a single one.
+Each challenge corresponds to the production of a product with one of the
+available complexities (C0, C1, C2, C3) in the \ac{RCLL} using either
+one or two \ac{RS}.\\
+For complexities C1, C2 and C3 the accumulated cost for mounting the required
+rings must be equal to 1, 2 and 3, respectively.
+\textbf{Task:} Produce all posted orders.\\
+\begin{table}[!htb]

+\end{table}
+
+\subsubsection{Exploration + C0 Challenge}\label{sec:challenge-combine-exp-c0}
+A simple production task on a field with unknown machine positions.
+The challenge is to produce a product of complexity C0 without receiving the
+machine positions at the start of the production phase, resembling a unified
+exploration and production phase.\\
+\textbf{Task:} Produce all posted orders.\\
+Beating this challenges yields 50 points.
+
+\subsubsection{RefBox Simulation Challenge}\label{sec:challenge-simulation}
+A competition on the agent level. The RefBox provides a set of actions
+that can be executed by sending dedicated commands to the refbox via protobuf.
+Hence no actual robot is required to participate.
+\textbf{Task:} Play a regular RCLL game through the RefBox simulation
+interface.\\
+Participating in this challenge yields points based on the achieved in-game
+points, see \reftab{tab:challenge-simulation}.
+Additionally, the team scoring the highest points overall gets awarded another
+$10$ points
