<T21> Fields at an event must be consistent with each other. There are many types of permissible aesthetic and / or logistical modifications that may be made to competition fields at the Event Partner’s discretion. If an event has multiple Head-to-Head competition fields, they must all incorporate the same permissible / applicable modifications. For example, if one Head-to-Head field is elevated, then all Head-to-Head competition fields must be elevated to the same height. Examples of these modifications may include, but are not limited to: Elevating the playing field off of the floor (common heights are 12” to 24” [30.5cm to 61cm]) Field control systems (see <T22>) Field display monitors Field perimeter decorations (e.g., LED lights, sponsor decals on polycarbonate panels) Field perimeter type (see <T23>) Utilizing the VEX GPS Field Code Strips Note: If an event uses a set of dedicated fields for Robot Skills Matches, there is no requirement for them to have the same consistent modifications as the Head-to-Head fields. See <RSC6> for more details.
