Interesting arguments though

From the 2013 Inspection Checklist:

No Prohibited Materials – e.g. sound, lasers, noxious or toxic gases or inhalable particles or chemicals <R08>

Referring to Sec 4 of the Game Manual:

R08 ROBOT parts shall not be made from hazardous materials, be unsafe, cause an unsafe condition, or interfere with the operation of other ROBOTS.

Dry ice poses handling and asphyxiation risks. Also, if dry ice is put in a tightly closed container, the container may burst.

The grey area is if the dry ice is not part of the robot, but instead is used to cool components between matches, etc. In this case, dry ice is no longer an inspection issue, but the safety advisers may prohibit its use in the pits.
