The Standard Tetra Weight

[Katie Reynolds]

3.3 SCORING OBJECTS
The Scoring Objects for the game are three-dimensional tetrahedral shapes with each face in the form of an equilateral triangle, known at “Tetras.” Each edge of the Tetra is defined by a 30-inch length of 1-1/4” Schedule 40 (approximately 1.6” OD) PVC pipe. The ends of the pipes are attached to “Tetra Connector” to form each apex of the Tetra. The Tetra Connector is a custom injection molded part. When properly constructed, a Tetra stands approximately 28 inches tall and weighs approximately 8-1/2 pounds. Each Tetra is colored either red or blue. When a Tetra is placed in a scoring position, it will score points for the alliance of the corresponding color. Forty Tetras of each color will be available for each match.

Two special Vision Tetras of each color will also be used in the match. The basic construction of the Vision Tetras is identical to that of all the other Tetras. The Vision Tetras will also have an eight-inch tall band of green HDPE attached to three sides of the structure that is intended to be detected by the Robot vision system. A vision tetra weighs approximately 12-1/2 pounds.
