The Pitch is 8ft by 4ft pitch and surrounding black wall is 1ft high.
The white lines are 5cm wide.
The goals sizes will be: width = 60cm and height = 18cm.
The ball is a red golf ball.
The robot dimensions should be within in the following sizes: length = 20cm, width = 18cm and height = 18cm.
Because of changes to the top plate we are refining the rules for robot dimensions as follows: Sensors and reasonable support for sensors may protrude up to 1cm beyond the given dimensions, on front, back, and each side. Up to 1cm may be used at the top to provide additional support for the top plate.
Each half is three minutes, with one minute between halves. If a team is not ready to play on time, the match may start without them (there strip marker being placed on the pitch in there absence) and they may even default the match. On the final day we will be running to a pretty tight time schedule so we will be fairly strict on the time keeping and are prepared to start matches with only side present on the pitch (plus the oppositions strip in goals) if needs be. We will review these times after the friendly tournaments and the match lengths may be changed accordingly.
The robots dimensions should fall with the dimensions of Length = 20cm, Width = 18cm, Height = 18cm. The robot dimensions will be judged as being between the two furthest out points on any given dimension. Any yellow or blue pieces of lego used in construction should not be visible from above. (Insulating tape and paper/card can be used to cover up the offending bricks) Any red lego used should not be visible from any of the sides (ie by the opposition robot, should they be using any form of colour sensors). No use of the red plastic ball from the lego kit as part of the robot. Your robot should have some kind of flat top or frame or fixing points for the strip to be stuck onto (for speed we may end using blutack to do so) No glue should be used on the robots to hold them together (if you can't brace it up solidly with lego then you are not using it right) No cutting, drilling, painting of lego on the robots The robot kits should be returned to us at the end of the project in the same condition we handed them out in. Yes the 20/80 ruling is in effect. Loose and/or trailing cables will need to coiled and cabled tied up. No flame throwers, catapults, crossbows. If a robot falls apart during play, the referee may choose to award the game to the opposing team. If using the lego light sensor you must switch the red LED off.
The robot should be capable of working out which goal is which in case of power failures and resets during the match or at least able to get the info via bluetooth from the vision system. In which case you are able to tell the robot which way it is aiming for. We have decided against implementing any form of remote assistant referee program.
You are encouraged to make the best use possible of the given facility's and equipment. However we reserve the right to restrict anything that we deem as being unfair or unsporting use. You are also restricted to using the equipment/parts/kit that has been (or can be) supplied to each groups equally, and kit that has been bought in under your group budget. This also includes the use of kit that has been brought in from home, which for the purposes of the project will be considered as items bought under the groups budget and looked at on an item by item basis.
The tournament draw will be made that morning with a rep from each group present as the "groups are drawn from a hat". A poster or two will be put up in the labs with the match line ups and times on it. As well as being posted on the newsgroup and course web page. Be aware that you may be required to play earlier than expected due to unforseen withdrawals. The strips for this year are going to be blue and yellow lego "T" shapes with the black circles on the green lego base boards that can be found on the pitch. They will be allocated just before kick off. A coin toss will be made and a member from each participating group will then decide which of the two colours they will be wearing and, which direction they will be attacking. Please note that you switch attacking direction but not strip colours at half-time. Each team will then have 1 minute to prepare for kick off. Which means you will have to be ready to attach the allocated strip to the top of your robot very quickly and input the direction information. Robots must be designed so that the T emblem can be easily attached between games. Blutack should not be required. The T emblem should be secure, and not fall off in normal play. As part of the advertising/product branding/presentation side of things in this project each group is expected to have a team name and logo. This team name or logo should be presented as a big, bold colour A4 print and placed on the pitch just prior to each match starting. (To help the video viewers identify who is playing.)
You will be allowed a minute between coin toss decisions being made and kick off to get your robot on the pitch and ready to play. The initial position for the ball is in the centre of the field. The initial position for each robot is facing forward, centred, with its back against its own goal line. If a robot cannot be placed on the field at the start of play we reserve the right to start the match without them (and field only there strip to aid the vision system of the other team)or we may forfeit the match as a 3-0 loss. The robots will be checked prior to the matches to make sure that they fit in with the rules on sizes and also that any colours that may conflict with any of the Vision Systems are covered up or removed. Please also note that you may be required to play earlier than expected due to unforseen withdrawals.
One team member will be allowed to act a coach/physio and be allowed to reposition/restart the robot as and when the referee allows As it is 1-a-side football, you may dribble the length of the field as long as the ball is not shielded from the opposing robot, in such a manner as they have no hope of attempting to tackle your robot, so we wil allow dribbling for distances longer than 500mm as specified by Robocup. The 80/20 rule as mentioned in the Robocup rules will be aplicable, (This is from all angles including above and below.) No lifting or carrying the ball. No deliberate covering of the ball from above or obscuring it from the camera. No chipping/flicking/kicking the ball above the surrounding wall No attempting fire the ball with such power that it will damage the opposition robot. Robot collisions will occur and when the robots bump into each and react to doing so; ie. stop and turn or reverse away from each other then play will be allowed to continue. We will however enforce the rule that if one robot rams another, particularly violently or repeatedly then a penalty kick may be awarded against the robot doing the ramming. If both robots ram each other violently or repeatedly then they and the ball will be returned to their initial positions. If either robot is stuck for 30 seconds, it may be returned to its initial position. If the ball is dead for 30 seconds (against the wall where it is impossible to kick, or not visible to the camera), it will be returned to its initial position. No violent behaviour towards other robot One group member only to interact with robot when allowed to do so by the referee during the match. You will be required to identify yourself to the referee before the match. Any other member of your group handling the robot during the course of the match without the referees prior consent will result in a penalty being awarded against you. To avoid confusing the vision systems we would like to request that those of you handling the robots don't wear the same colours as the strips or the ball. Penaltys will be used in event of a 0-0 draw. Freekicks require the opposition robot to be 50cm back from the ball. You can choose to attempt to score directly from a freekick. Deadballs (no ones ball) - both robots to be 50cm back from ball at restart of play. We will not prevent you from sending the ref's instructions or match score to the robot via bluetooth or prevent the nominated team member from switching the robot into a different playing mode program (when the ref allows interaction with the robot) but we would prefer to keep the match as freeflowing and hands off as possible. Running repairs to robots during the match must be carried out off the pitch. There is a black duck tape line around the pitch now which all spectators and participating team members are expected to remain behind during the matches so as not to confuse the vision systems ability to detect things. Each match will have a referee and a panel of three judges. Their decisions will be based fairly and evenly on these rules and the events of the matches. In the event of dispute the referees decision is final. (There however may be time allowed afterwards for post-match analysis and discusion)
All observers to stay one foot away from the pitch, so as not to confuse the participating teams vision systems. You will also be able to watch the matches on the projector in the level 3 open area as well as from the web feed
During play, a penalty will be awarded if a robot is touched without first obtaining permission from the referee. In a penalty, the kicking team places their robot first, and the defending team may then place their robot. The positioning for a penalty kick is that the robot taking the kick is placed, then the robot defending is placed. In all other cases, the only place a robot may be moved to is its initial position. The robot taking the penalty will then have up to 30 seconds to do so
In the event of a score draw, then the team who scored first will be called the winners. In the event of a no-score draw then the match shall go to penalty's(one each). Each game will have a panel of three judges. If the game is tied after one penalty kick for each side, the judges may decide either: (a) to toss a coin to determine the winner; (b) to award the game to the robot that they believe was technically superior; or (c) to allow an additional penalty kick for each side (if the game remains tied, the panel then decides between options (a) and (b)). As an incentive to do well in the friendlys, each friendly's two finalists will get a pass directly to the semi final stage of the next tournament, with the first round of matches involving the remaining four groups.
Each week's finalists, will get a pass into the next tournaments semifinal stages. The matches will be streamed live to the web and also recorded. The full tournament recording will be available from kick-off time. The edited match recordings will be made available to you to use for further simulation work from Thursday morning onwards.
"Unsporting Behaviour" is frowned upon and may result in the offending teams being penalised depending on the severity of the infraction this may vary from penalty kicks being awarded against them up to and including exclusion from the tournament. Some examples of unsporting behaviour include:- The use of anything that may disrupt a robots capability to use its sensors effectively, in particular the use of magnets to disrupt compass sensors. The sending of direct commands via bluetooth to the robot during the match is not permitted. Once the whistle has blown for the match to start the robot is suppossed to be autonomous. It is not a remote-control robot competition.
These rules may be amended or added to as the project progresses so please check back here and the newsgroup:- eduni.inf.course.sdp for updates.
