==Playing field and scoring== <gallery perrow=4 heights=250px widths=250px> File:43375_-_1995.png|The playing field [https://www.frcarchive.com/index.php?q=post/view/43375] File:43378_-_1995.png|Ramp dimensions [https://www.frcarchive.com/index.php?q=post/view/43378] File:43379_-_1995.png|Speed Bump dimensions [https://www.frcarchive.com/index.php?q=post/view/43379] File:43380_-_1995.png|Field Goal dimensions [https://www.frcarchive.com/index.php?q=post/view/43380] </gallery> The field is a carpeted modified "T" with three titular ramps leading up to a platform at the top of the "T". Two uncarpeted slopes connect the center ramp with the two side ramps and a back wall and netting separate the drive teams from the field. The top of the T is 30 feet wide and the raceway extending downwards is 12 feet wide. The total length of the field is 40 feet. The thicker portion of the field including the ramps and field goal is 12 feet long, with angled corners parallel to the slopes transitioning the platform area to the raceway. The raceway includes the four inch tall speed bump, flanked by two eight inch tall walls, halfway down its 28 foot length. The platform is four feet square and 30 inches off the ground. The field goal is made from two inch inner diameter PVC and is located 15 inches from the front edge of the platform, part way down the front Ramp. The top of the horizontal bar is five feet from the floor, with uprights six feet apart and extending up four feet above the horizontal bar. The field is surrounded by a 4" wooden perimeter with a steel fence installed on top. <gallery perrow=3 heights=250px widths=300px> File:3221 - 1995 1995nh frc144 frc157 frc191 match robot.jpg|Teams [[frc157|157]], [[frc191|191]] and [[frc144|144]] setting up their robots for a match at the [[1995nh| New England tournament]] [https://www.frcarchive.com/index.php?q=post/view/3221] </gallery> Three robots in the red, yellow, and blue positions play simultaneously in the seeding rounds and earlier rounds of playoffs, with one on one matches later on. Robots start lined up facing away from the ramps and towards the cluster of six balls down the raceway. Each team has two matching color balls, one 24 inches and one 30 inches in diameter, that start at the end of the field and past the Speed Bump. To count as scored, the ball must break the vertical place above the horizontal bar of the Field Goal uprights. Scoring a 24 inch ball is worth two points and scoring a 30 inch ball is worth three points. The team that matches the color of the ball, not necessarily the team that scored it, receives the points. Tiebreaks are determined first by the large colored ball at the highest elevation from the floor and then by the large colored ball closest to the center of the platform. Each match lasts two minutes. The control system is automatically enabled and disabled when matches begin and end. ===Game strategy=== Although it was written in the rules that grabbing or grasping the field goal was against the rules, and the intention seems to be that balls would be shot or lifted and dropped through the field goal, the overwhelmingly dominant method of scoring was for robots to collect a single ball in a large fork or other grabber and lift it completely through the field goal so that it counted as scored and then bring the grabber back through the field goal to score again in the other direction. Team Update #1 clarified that this was a valid method of scoring as long as the ball fully passed through the field goal. Arms and other lifting mechanisms could not rest on top of the Field Goal and some robots would tip up on one set of wheels as the weight of their arm and grabber passed through the field goal. Catapults were generally outperformed by robots that would sit behind the field goal on top of the ramp. Some robots incorporated stabilizers that would be deployed when in position at the top of the ramp. <gallery perrow=3 heights=250px widths=300px> File:42678 - 1995 1995cmp frc-53 frc100 match robot.png|Teams [[frc-53|-53]] and [[frc100|100]] scoring back and forth at the [[1995cmp|National championship]].

Scoring first was almost always a tactical advantage. From one of the side starting positions it was usually more advantageous to wait for the bump to clear and grab one of the larger balls to score more points. Being able to score from the central ramp as well as the platform behind the field goal was also advantageous, especially if not scoring first<ref>[[:File:1995_New_Hampshire_recap.pdf|New Hampshire Regional recap]]</ref>.
