Start and Goal
4.1.

Mission and Start
Basically, a challenge starts at every mission or task.

4.1.1.
4.2.

Gate and Line
4.2.1.

A gate with red and blue poles is placed at a start point, goal, and checkpoints.

4.2.2.

Each gate is equipped with numbered flags starting from “1”, which is referred to as a gate
number.
The line that connects both sides of the gates is called a gate line (As with a gate number,

4.2.3.

referred to as gate line No. 1).
4.2.3.1.

A gate line at a start point for each mission (or task) is called a start line.

4.2.3.2.

A gate line at a checkpoint for each mission (or task) is called a checkpoint line.

4.2.3.3.

A gate line at a goal for each mission (or task) is called a goal line.

4.2.3.4.

A robot has to start from a start point and aim at the gate of the goal by passing thegate lines as checkpoints in the numerical order.

4.2.3.5.
4.3.

Duration
The duration of the challenge is described in Table 1-1.

4.3.1.

4.3.1.1.

WRS Tunnel Disaster Response and Recovery Challenge Rule Book Ver.1.1.1
8/37

The procedure for a start is as follows.

4.4.3.

4.4.3.1.

Participants set up necessary equipment for robot operation on the table in thecontrol station.

4.4.3.2.

With the referee’s call to start, the mission starts along with the preparation.

4.4.3.2.1.

Preparation includes a network connection between the robot operation
computer and the competition system.

Time starts with the announcement of a start.

4.4.4.

4.5.

Goals
4.5.1.

When a referee confirms a robot marker passes a goal line, the mission is ended.
4.5.1.1.

If 2 robots are used, the robot marker of both robots must pass the goal line and be
confirmed by the referee to count as a goal.

4.5.2.

The robot marker, which is placed at an easily recognizable point of the robot for a referee,is the position of a sphere attached to the robot.
4.5.2.1.

4.5.3.

The sphere must be presented with the field model.

When the goal is reached, the mission (task) ends and the timer stops.
4.5.3.1.

If 2 robots are used, the goal must be reached by both before the mission (task)
ends and the timer stops.

4.5.4.

A robot can reach the goal without completing all the tasks required in each task (subtask),such as target identification.
4.5.4.1.

In this case, there are no point elements for unattempted tasks.

4.5.4.2.

Additional point elements (time) will not be added.

※ Refer to 6.3.5 for information regarding additional point elements (time).
4.6.

Checkpoints
4.6.1.

Checkpoints are placed between the start and the goal.

4.6.2.

A referee has to ensure that a robot marker passes the checkpoint line.
4.6.2.1.

If 2 robots are used, both robots must pass the checkpoint.

4.7.

Restarting
4.7.1.

Participants can request a restart.
4.7.1.1.

Restarting is starting again after the initial start.

4.7.1.2.

Restarts must comply with the starting procedure.

4.7.1.2.1.
4.7.2.

4.7.3.

In case of restart, the field conditions return to the initial state.

Preparation for the restart begins with the referee accepts the restart request.
4.7.2.1.

The restart cannot be withdrawn once the referee accepts it.

4.7.2.2.

There is no need to restart if abstention is requested after a restart is accepted.

Participants can request a restart for their own convenience.
4.7.3.1.

In case of restart, the restart line is any line set by the system (start line,
checkpoint line) behind the position where the restart is requested.

4.7.3.1.1.

4.7.4.

The position of the lines will vary by mission.

4.7.3.2.

Scoring elements and penalties that occur behind the restart line remain valid.

4.7.3.3.

Scoring elements and penalties that occur in front of the restart line are withdrawn.

When a restart is accepted, time stops and the field returns to the initial state. The restart
beings with the referee’s announcement, and time starts again.

4.7.5.

The duration of the mission after the restart is the time remaining after subtracting the time
when the referee accepted the restart from the of the official mission duration.
E.g.) If a restart is accepted at 4 minutes 30 seconds in with a 10 minute mission time,
the remaining time after the restart is 5 minutes 30 seconds.

4.7.6.

There is no limit to the number of restarts.

4.7.7.

When a referee decides the participants need a restart, the restart is mandatory. This
restart is called a forced restart.

4.8.

Abstention
4.8.1.

Participants may abstain from all or part of a mission (task).

WRS Tunnel Disaster Response and Recovery Challenge Rule Book Ver.1.1.1
10/37

4.8.1.1.
4.8.2.

Participants must request a referee for the abstention.

In case of abstention during a challenge, points are given only when a robot passes througha checkpoint line.
E.g.) When Task A and B are executed consecutively, points earned in task A are
valid regardless of abstention during task B after the completion of task A.

submitted in the standard point-cloud format.

WRS Tunnel Disaster Response and Recovery Challenge Rule Book Ver.1.1.1
15/37

6.3.4.

Additional points (position) are given for successful identification of an accurate target
position in a mission (task).
6.3.4.1.

If the coordinate of the position is within the radius SR (=radius of a target pipe),
100 % of scoring element (position) is given. 50 % for within 2SR and 25 % forwithin 3SR. (See the following figure).
E.g.) For a 4 point task, 4 points in SR, 2 points in 2SR, and 1 point in 3SR are

given.
E.g.) For a 3 point task, 3 points in SR, 1.5 points in 2SR, and 0.75 points in
3SR are given.
※ The number of points are subject to change.

Fig. 6-3-1: Radius from the center of the target

6.3.5.

Additional point elements (time) are awarded according to the recorded time for a mission(task).
6.3.5.1.

Points are awarded for each mission (task) if the goal is reached before the specified
time.

6.3.5.1.1.

2/60 of a point is awarded for each second remaining.
E.g.) If 1:34 is remaining, 94 sec. x 2/60 = 3.1 points

■

The amount of points awarded for the additional point element(time) may change.

6.3.5.2.

If a tool is used, and the tool is not brought to the goal, the above points will not beawarded.

6.3.6.

Point Deductions
6.3.6.1.

If the mission (task) specifies a reduced point element, performing the action forthat element will lead to point deduction.

6.3.6.1.1.

A referee may impose point deductions in addition to those specified asdetermined appropriate.
■

The point deduction will be evaluated by the referees and thechallenge committee, and the chair of the challenge committee will
make the final decision.

leading up to competition.

6.4.1.4.

In the case of disqualification, an explanation will be provided to an individual
representative from each team, opinions will be gathered, and after deliberation
among the referees and challenge committee members, the chair of the challengecommittee will make the final decision.
