Discover Mechanical Engineering features a contest for teams of
student built robots. This page contains the official rules for the
tournament. The referee's rulings are final.
Rules of the Game
- Duration of Play
- The game will consist of 16 minutes of play, divided into into two
halves of eight minutes each.
- There will be a 2 minute break between the halves.
- Starting the Game
- The game will begin with one team in possession of the ball. The
other team will have possession at the beginning of the second
half.
- Each team will place their robots on their half of the field in
any configuration they choose, with the exception of the central
circle. Only one robot, chosen from the team which has possession
of the ball, will be allowed in that central circle.
- Play will commence at the discretion of the referee.
- Scoring
- A team will be considered to have scored a point if at any time
50 percent or more of the ball is in the goal defended by their
opponent.
- Each goal will be worth one point.
- Stoppage of Play
Play will be halted for the following reasons. However, all calls are
at the discretion of the referee. The referee reserves the right to
stop play at any time.
- The ball has left the field. If the ball leaves the field then the
defending team gets possession of the ball on their half, while the
other team must remain on their own side.
- A score is made, where score is defined in Rules section 3.1. After the stoppage, the team which lost the point
will start with the ball in a manner identical to the start of the
game.
- If a robot breaks down, the following procedures will be followed:
- Play stops.
- The broken robot is removed from the playing field.
- To equalize team size:
If a player is unintentionally at fault, that player's
robot is also removed.
If no one is at fault, the broken robot and its player will
be replaced by a mentor robot and mentor.
- Teams may return to normal if the broken robot is repaired.
- The ball is returned to play as if it had left the field.
- Intentional damage to another robot is unacceptable. If it
becomes apparent that an individual is intentionally attempting to break
another robot, then that individual's robot will be removed from play and
a mentor robot, controlled by a mentor, will replace it.
The offending individual may return to play in subsequent games
at the referee's discretion. If the referee refuses to return the individual
to play, the mentor will continue as a substitute.
- Winning
- The team with the most points at the end of the second half will
be declared the winner of the game.
- In the event of a tie, a shoot-out will be used to determine the
winner, with the shoot-out procedure as described in Rules section
6.2.
- Special Procedures and Provisions
- Penalty kick procedure. One robot from the
team allowed the penalty kick will be placed near the starting
circle. No other robots will be allowed on the field. A stationary
ball will be placed in the center of the field. At the referee's
signal, the robot on the field will be allowed to strike the
stationary ball in an attempt to score a goal. The robot will not be
allowed contact with the ball once it leaves the central circle. Once
it has become clear that the kick has or has not resulted in the
scoring of a goal, the team which was allowed the penalty kick will
start in possession of the ball.
- Shoot-out procedure. A coin will be flipped to
determine which team shoots first. The kick procedure will be
identical to the kick procedure described for a penalty kick, as
described in Rules section 6.1. If the winner of
the coin toss scores a goal, one point will be added to their
score. Then, the loser of the toss shoots. If they score a goal, one
point will be added to their score. If one team now leads in score,
they will be declared the winner of the game. If the score remains
tied, then the shoot-out procedure will be repeated until one team
becomes the winner.
- While these rules are designed to be fair and complete, it is
acknowledged that they may not provide adequate guidance for judgement
in special or unusual circumstances. The referee is granted the right
to use their discretion in all matters to reach a fair and reasonable
course of action.
