R205       *Do not make a mess on the FIELD. ROBOTS may not contain any materials which if unintentionally released would damage the FIELD, other ROBOTS or delay the start of a MATCH due to required clean-up or decontamination.  Lubricants may be used only to reduce friction within the ROBOT and must not contaminate the FIELD or other ROBOTS.

Lubricants (e.g., grease) used on the ROBOT must not be excessively applied such that they spin off or drip off during normal ROBOT operations on the FIELD.

Additional examples of items that will violate this rule include (but are not limited to):

-        any ballast not secured sufficiently, including loose ballast such as sand, coffee beans, kitty litter, or ball bearings, such that it may be released on the FIELD during a MATCH

-        liquid or gel materials

-        tire sealant, and

-        other lubricants including graphite powder
