[R06] Traction devices may not have surface features such as metal, sandpaper, hard plastic studs, cleats, or other attachments. Traction devices include all parts of the Robot that are designed to transmit any propulsive and/or braking forces between the Robot and the Court.
Would a
metal wheeled caster or a steel balled
ball transfer violate this rule?
It seem not since the purpose of the device is not to provide propulsive or braking forces. But I sort of had an idea in my head that the rule was "only plastic touches the floor" but as I read it now, that is far from the rule.
