I get the idea but it is really hydraulic fluid that the robot needs? It doesn't even look like the robot is using hydraulics, or that "containing the spill" does anything except keeping the fluid in the center of the room. Unless I am missing something, there is no mechanism that actually disables the robot if it fails to keep the fluid in the center. I know it is art, but I think making it real would sell it better.
