6.2.3 LAUNCH PADS

Three 48-inch by 96-inch LAUNCH PADS are marked on the CRATER floor for each ALLIANCE. The LAUNCH PADS indicate the areas in which the ROBOTS and TRAILERS must be positioned before the start of the match. The LAUNCH PADS locations are shown in the drawing below (note that the LAUNCH PAD locations are emphasized in this drawing for the purposes of illustration - the actual location markings will be less intrusive and will not detract from the visual appearance of the CRATER). For precise dimensions and locations of the LAUNCH PADS, please refer to the official “FE-00030 - 2009 Arena Layout and Marking” drawing.
