AIWC Rules P3
Previous Page - Section 2 - Rules (2/9)
AI-driven robots sometimes cannot track the soccer ball correctly. In case when all robots of two teams fail to track the ball, the game can be in a deadlock state where no changes occur in the soccer field. Also, since the soccer field is surrounded by solid walls unlike human soccer field, the robots can push the ball toward the walls and several robots trying the same can make the ball stuck between the walls and robots that a deadlock state can be caused as well.
To prevent deadlock states stalling the game, deadlocks are detected and handled. In AI Soccer, a deadlock is defined as the soccer ball moving slow speed of less than 0.4 m/s for 4 seconds. Each deadlock is handled differently based on the region where the deadlock happened in the soccer field.
4-1. Deadlock in Corner Area
When a deadlock happens in one of four corner areas, the game will proceed to a corner kick. The ball ownership in the corner kick is determined as follows:
① The number of robots in that area of interest is counted for two teams and the team with more robots in that area will get the ball ownership.
② In case when both teams have the same number of robots in that area, their average distance to the ball will be measured and the team with smaller average distance to the ball will get the ball ownership.
③ If the average distance is the same too, the team with their goal located farther from that area will get the ball ownership.
4-2. Deadlock in Penalty Area
When a deadlock happens in one of two penalty areas, the game will proceed either to a penalty kick or a goal kick. The ball ownership in the penalty kick or the goal kick is determined as follows:
① The number of robots in that area of interest is counted for two teams and the team with more robots in that area will get the ball ownership.
② In case when both teams have the same number of robots in that area, their average distance to the ball will be measured and the team with smaller average distance to the ball will get the ball ownership.
③ If the average distance is the same too, the team with their goal located farther from that area will get the ball ownership.
If the ball owner is the team with their goal located farther from that area, the game will proceed to a penalty kick. Otherwise, the game will proceed to a goal kick.
4-3. Deadlock in Other Regions
When a deadlock happens in regions other than the corner and penalty areas, the game will proceed to a ball relocation.
