Dry Ice on Robot?

Also, wouldn't the water be then considered a hydraulic fluid?

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)

So therefore your team would have to prove that no fumes can escape your robot during operation. The problem then would become the dreaded "what-if" questions that inspectors like to ask.

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?
