Triballs

The Triballs are the triangular balls that each robot will try to get under the opponents net or onto the opponents side of the field. The triballs may be found in either a green neutral color, or a red or blue color designating each alliance. At the beginning of the match each team has 22 triballs to Matchload onto the robot in order to get them to the opponents side of the field. unnamed


Alliance Goals

The Alliance Goals can be found on opposite sides of the field and sit on bars attached to the outer walls of the perimeter. There is a net that connects to the front goal support and rests on the back perimeter, creating an angle. The goals can be found in two colors, red and blue, to designate which alliance scores in each Goal. unnamed Each Alliance Goal is 47.13" wide, 23.08" long, and 5.78" tall. The front of the net is raised to 5.78" and the back of the net sits at 11.5", creating a 14.27° angle.


Matchloading Bars

There is a Match Loading Bar in each of the four corners of the field specified by Alliance Color.

The Match Loading Bars are 30" in length and 2.38" in diameter. unnamed

There is a vertical plane that starts at the front of the Match Loading Bar. This plane is used to dignify whether a robot is able to matchload. A robot has to be crossing the plane of the matchload zone in order for matchloading into the robot to occur.


Elevation Structures

There are 2 Elevation Structures found at both ends of the Middle Barrier, and they attach to the perimeter of the field. The structures can be found in two colors, red and blue, to designate which alliance can use each structure.

The Elevation Bar is 11.63" off the ground as well as 21.89" in length. The Elevation Pole is 30.23" tall. Both the Elevation Bar and Pole are 2.38" in diameter. unnamed

These structures allow teams to gain up to 20 points for the highest hang. There is an Elevation Measurement Stick that is used to determine what Elevation Tier the robots are at. Some teams won't have the mechanics needed to hang, giving the teams that do an advantage.


Middle Barrier

There is a barrier located at the center of the field separating the field into two sides. Each team at any time is allowed to traverse over the Middle Barrier to get to the other side.

The Middle Barrier is 91.88" in length and 2.38" in diameter. The barrier is raised 0.50" off the ground and 2.88" at its highest point. unnamed

During the match, if 2 robots from the same alliance are on the same side of the Middle Barrier it is considered Double-Zoning. If Double-Zoning occurs, the opposing alliance is allowed to descore from the opposite's Alliance Goal.


Matchloading

Matchloading is the action of placing Triballs onto your robot in order to score points by getting them to the opponents side of the field. In order to matchload the robot must be within the Matchload plane

Autonomous

The Autonomous period is at the beginning of every head to head Over-Under match, You must code instructions for your robot to follow during this 15-second period as it disables all driver control. The goal of the Autonomous period is to score more points than the other alliance, the alliance that has the most points at the end of the 15 seconds receives the Autonomous Win Point, this grants that team 8 points at the end of the match.
