Dry Ice on Robot?

As to how you could use dry ice to provide power to a robot... YouTube: Stirling Engine Running On Dry Ice. Maybe you could use the Stirling engine to power a fan to cool your motors? The energy for this would, as you point out, not be coming from the dry ice but from the ambient temperature, and under those terms could be ruled illegal.

Excellent example. This makes my head hurt. I can just see the new rule now:

"G53: Ambient energy of any form present within the boundaries of the PLAYING FIELD may not be harvested and employed by a ROBOT. This includes; thermal energy present in FIELD ELEMENTS, carpet, atmosphere, or other ROBOTS; radiant or photon energy from venue lighting; acoustic energy from the PA system or spectators; and magnetic or cosmic energy fields or streams which may exist within the venue.
