Event Description: Robo Soccer
- Robots will be measured in an upright position with all parts extended. A robot’s specifications must not exceed the following limits:
- At any point of time and any configuration of the bot, it should fit inside a box with horizontal cross section of 30cm*30cm*30cm (l*b*h).
- Weight must not exceed 3kilos.(There will a tolerance of 0.5kg allowed).
- Power supply should be on-board and maximum voltage between any two points on the circuit at any given time should not exceed 12V DC, 1.5A.
A student team, can have a maximum of 4 members. Participants should possess a valid identity card from their respective institution
- The Field:
2.1 Playground Surface and Dimension
The field is on a marble floor with dimensions 680cm x 340cm. The playground is considered flat if a ball placed anywhere on the field does not start to roll.
2.2 Markings on the Playground
The center circle/square will have a radius 50cm to 60cm. The arc will be 25 cm along the goal line and 5 cm perpendicular to it. Neutral points will be marked on the field to facilitate resetting the positions of the robots in case there is a stalemate (lack of progress).
**The dimensions of the track is subjective to change.
2.3 The Goal
The goal is ~90 cm wide and ~45cm height.
2.4 The Goal Line and Goal Area
The goal line is the line just in front of the goal. The goal areas are comprised of the area contained by the rectangle 90 cm x 50 cm.
2.5 The Ball
A ball of ~15 cm diameter is used.
The game will consist of two halves. The duration of each half is 5-minutes. There will be a 1-minute break in between the halves. The game clock will run for the duration of the halves without stopping.
At the start of the first half of the game, a referee will toss a coin. The team mentioned first in the draw shall call the coin. The winner of the toss can choose either which end to kick to, or to kick off first. The loser of the toss will settle for the other option. After the first half, teams will switch sides. The team which does not kick off in the first half of the game will kick off to begin the second half of the game.
Suppose Team A pushes the ball and moves towards the goal post of Team B to score and crosses the line indicating half of the field, Team A cannot push the ball back into their half of the field
A robot cannot hold a ball. Holding a ball means taking full control of the ball by removing all of its degrees of freedom. If a ball stops rolling while a robot is moving or a ball does not rebound when rolled into a robot, it is a good indication that the ball is trapped.
A goal is scored when the ball crosses the goal line. Goals scored either by an attacking or defending robot have the same end result: they give one goal to the team on the opposite side. After a goal, game will be restarted with a kick-off from the team who received the goal against.
If the stalemate situation doesn’t improve even after 40 seconds then the positions of the robots will be moved to the neutral points (see section 2.2)
If a robot is damaged, it has to be taken off the field and must be fixed before it can play again.
Interruption of the game
A referee can stop the game if there is a situation on or around the field which the referee wants to discuss with an official of the tournament or if the ball malfunctions and a replacement is not readily available.
If special circumstances, such as unforeseen problems or capabilities of a robot occur, rules may be modified by the referee.
All decisions during the game are made by the referee or the referee assistant who are in charge of a field. During gameplay, the decisions made by the referee and/or the referee assistant are final. Any argument with the referee or the referee assistant can result in a warning. If the argument continues or another argument occurs, this may result in immediate disqualification from the game.
Violations / Disqualification
Teams that violate the code of conduct can be disqualified from the tournament. It is also possible to disqualify only single person or single robot from further participation in the tournament.
- 12.If there are less than 5 teams registered , event will be cancelled.
