R201       *No digging into carpet. Traction devices must not have surface features that could damage the ARENA (e.g. metal, sandpaper, inflexible studs, cleats, hook-loop fasteners or similar attachments). Traction devices include all parts of the ROBOT that are designed to transmit any propulsive and/or braking forces between the ROBOT and FIELD carpet.

Rule R202
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.
Rule R502
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.
Rule R206
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.
Rule R205
R205       *Don’t contaminate the FIELD. Liquids, gels, greases and fine particles must not contaminate the FIELD or other ROBOTS.
