The official FIRST playing field specifications can be found at http://www2.usfirst.org/2004comp/3-TheArena.pdf.
The main method of scoring is moving the small balls found around the field into one or both of the team’s 2 goals on the field. There are 4 goals on the field, 2 small mobile goals and 2 large stationary goals. One mobile goal and one stationary goal are assigned to each team. Every small ball put into the team’s goals will count as 5 points. In addition to the 6 small balls in each player’s station and the 18 balls found in large baskets above the players’ stations, there are 2 bonus balls located on pedestals just outside the playing field boundaries. These are the only objects outside the playing field that the robots are allowed to touch during the match. In addition to each bonus ball counting as 10 points when placed in a goal, if the balls are removed from their pedestals during the 15 second autonomous period, then the baskets above the players’ stations will dump their balls onto the field. If the bonus balls are not removed during the autonomous period, then the baskets will dump their loads automatically after 45 seconds.
Besides the small balls, there are also 3 very large multiplier balls located around the field. They are so large that they cannot fit inside the goals, but they can rest on top. These balls are not worth any points by themselves, but they can multiply the points scored by the small 5-point balls. If there are 10 small balls in a goal (50 points) with a multiplier ball on top, then the score is doubled, making the score 100.
The last method of scoring points involves the chin up bar. If the robot can grab the bar and suspend itself off the ground at the end of the match, then that robot’s team receives 50 more points.
