Tetra
From FIRSTwiki
The Game Object for the 2005 Game. Tetras were made up of 6 pieces of PVC, joined together by a custom made plastic head. This formed a skeletal pyramid like structure that could be stacked on top of each other. Tetras were alliance specific, with red tetras giving points to the red alliance, and blue tetras giving points to the blue alliance. Vision tetras had green panels on 3 sides, allowing them to be detected by the CMUcam2 autonomously. During autonomous mode, these could be scored to earn additional points.
