Dry Ice is frozen Carbon Dioxide.
Dry ice, sometimes referred to as "Cardice" or as "card ice" (chiefly British English), is the solid form of carbon dioxide. It is used primarily as a cooling agent. Its advantages include lower temperature than that of water ice and not leaving any residue (other than incidental frost from moisture in the atmosphere). It is useful for preserving frozen foods, ice cream, etc., where mechanical cooling is unavailable. (wikipedia)

If CO2 is toxic to humans, then the drive team could be disqualified.
There are far better ways to cool motors. Cooling fins, Heat sinks, airflow.
Did you want to create a mystery mist around your Robot? Kind of like the lighting schemes that many teams use?
