R202       *No exposed sharp edges. Protrusions from the ROBOT and exposed surfaces on the ROBOT shall not pose hazards to the ARENA elements (including SCORING ELEMENTS) or people.

R502       *Only 4 propulsion motors. A ROBOT may not have more than 4 propulsion motors. A propulsion motor is a motor that enables the ROBOT to move around the FIELD surface (i.e., carpet). Motors that generate small amounts of thrust as a secondary or incidental feature are not considered propulsion motors.

R206       *Don’t damage SCORING ELEMENTS. ROBOT elements likely to come in contact with a SCORING ELEMENT shall not pose a significant hazard to the SCORING ELEMENT.

R205       *Don’t contaminate the FIELD. Liquids, gels, greases and fine particles must not contaminate the FIELD or other ROBOTS.
