1 Wheeled Robot Rugby Name of Event: Wheeled Robot Rugby Robots per Team: 5 (one robot per participant) No. of Players: Robot Control: Event Summary: 5 players/team (max) Remotely Controlled Rugby is a team sport where a plum-shaped ball is brought to the end goal to score. The game will have 5 robots on each side trying to go after the same ball and score a goal. Robots must be able to withstand the abuse of bumping and bring the plum-shaped ball across the goal line. Objective Robot The objective of the game is for your remotely controlled robot to bring the plum-shaped ball across the goal line and gain the most number of points or score Robot Dimension and Specifications The robot is required to use INEX microcontroller The outer shape shall be within the rectangular frame, width = 20 cm and depth = 20 cm Weight is up to 3000g including accessory parts. The remote control system is not included in the weight. A 1000g weight class is played separately The remote control system can be radio control or Bluetooth. Jamming or interfering with opponent s frequency is not permitted In order to be able to distinguish between the two teams robots, the following shall be applied: a. Display numbers of "1, 2, 3, 4, 5" (for the first team) and letters A,B,C,D, E (for the second team) in identifying individual robots with 3 cm or more in length and width b. The numbers are displayed on the top or side c. To unify the robot's color for team identification, display numbers with complementary colors that are easy to see Robot Restrictions Do not incorporate interfering radio wave generator or interfering Bluetooth Do not damage the ball itself or deliberately hide it Do not mount a device to fix the ball to the robot Do not use parts that damage the playing field or contaminate it.

2 Game Elements Do not set up a device that contains liquid, powder and gas and blows against the opponent Do not incorporate an ignition device Devices separating the robot body should not be built in The robots in 1Kg Category should have a built-in motor driver on the board. External motor drivers are NOT allowed. The robots in 3Kg Category is allowed to use external motor driver and is OPEN to all MAKES Playing Field Figure 1. Playing field The playing field is a rectangle with a length of 600 cm and a width of 300 cm, consisting of two goal areas and one playing area. The long side is called a side line, and a short side is called an end line The distance from the center of the court to the goal line is 250 cm. The goal area is from the goal line to the end line (50 cm) Each end line will have two goal posts behind the goal line. The goal posts will have a crossbar 20 cm high. The distance between the goal posts is 60 cm. The total height of the goal post is 100cm. The thickness of the goal post cannot exceed 5cm. It will be at the center of the end line. 100 cm 60 cm 20 cm Figure 2. Goal Post

3 The circumference of the field shall be surrounded by a protective wall with a height of at least 10 cm. This may be made of wood, aluminum, or other materials as long as it meets the height and will not be dislodged when hit by a robot The playing field s surface is made up of polycarbonate. There are lines 50 cm apart parallel to the end line Players are positioned and will operate their robots on the playing area The Ball Rugby Mini Ball Size to 40 cm 26 to 28 cm Figure 3. The Ball Game Proper 4.1. Start Players place all robots within their goal area. Teams may operate the robots to test them before the start. When the referee gives a ready signal, all robots must be within the goal area and players at the playing area The referee places the ball at the center of the playing field (after the ready signal is given). Referee then blows the whistle to indicate the start of the match. After the whistle, all robots may exit the goal area Temporary match suspension. A match is suspended under the following conditions: a. When the ball jumps out of the side line b. When it is judged that a scrum for 5 seconds is in progress and the game progress is not made. Scrum means restarting play after a stoppage which has been caused by a minor infringement c. After a successful try and a conversion is in progress d. When an offside foul is called.

4 Game resumption after a suspension a. Resuming after a (ball jumps out): Referee puts the ball at the center of the field in the line position where the ball comes out. The team that touches the ball before going out places their robots behind the goal line. The opposing team places their robots 50 cm away from the ball. The game resumes with the signal of the referee. In the event that the referee cannot decide which team puts the ball out, b positioning is followed b. Resumption after b (scrum): Referee places the ball at the center of the field in the line position closest to the position of the scrum state. Teams place, place their robots 50 cm away from both positions and resumes with the signal of the referee c. Resuming after c (try-conversion): Referee places the ball in the center ball place. The team that scored places their robots 150 cm behind the ball. The opposing team places their robots on their side in a position 50 cm away from the goal d. Resumption after d (offside): Referee places the ball at its last position when the offside is committed. The team committing the offside places their robots 150 cm away from the ball while the opposing team places their robots 50 cm away from the ball. The game resumes at the signal of the referee e. Restarting after the interruption of the game shall be promptly done End The referee will give a long whistle blow to indicate the end of the game. All teams must stop operating the robot Scoring Successful try = 4 points, Successful conversion = 6 points When a ball enters the goal area, and the opposing team s robot comes in contact with the ball, a successful try is called. If the ball is removed from the goal by the home team before a contact is made, no score is counted. The match continues.

5 After a successful try, only one robot of the scoring team remains. All other robots are removed from the field. The ball is placed by the scoring team in any part of the field or manually loaded to the robot and is aligned to the point where the try is made. One robot from the scoring team will be given 10 seconds to throw/kick the ball between the goal posts and above the crossbar of their opponent s goal When one team scores 9 points more than the other team, the game ends. Timeout 5.1. A robot that comes out of the playing field during a match can only be placed back during a temporary suspension. It is temporarily out of the game Each team has two 15 second timeouts. Timeout can be requested during a temporary suspension. Players do this by giving one of their two timeout cards to the referee Each team has two repair cards. During a temporary suspension, players can give the referee one repair card for one robot to be removed and repaired. The game will resume without the robot under repair. The robot can be placed back only during temporary suspension. Maintenance of robots can only be done in the player s area There cannot be any robot replacement or player replacement When a player suffers a physical injury and needs medical attention, the game will be temporarily suspended and the player leaves to seek medical attention. The game resumes after the departure of the player with no substitution. The suspension will be treated as a scrum. Fouls and Penalties 6.1. When a player leaves the player s area when the game is in play. When the player leaves the playing area during a temporary suspension without the referee s permission. In both cases, 1 point is awarded to the other team for every player When a robot starts to move forward before the start whistle or notice of the referee. The other team is awarded 1 point for every instance When there is an act which seems to harm the fairness of the game An Offside foul is called when one or more robots get ahead of the ball. Disqualification 7.1. Violent, slanderous behavior and other acts contrary to fair and good sportsmanship Failure to correct one s action after a foul, or continuously committing a foul even after a referee s warning All disqualifications apply to the entire team. The team will lose the match and additional 9 points awarded to the opposing team A disqualified team s ability to play succeeding matches depends on the tournament organizer.
