Setting...Underwater, future
Conflict...main character vs environment
Climax...the robot pours the water from the plant in to his water tank
Symbols...water is a symbol of life
plants is a symbol of environment
Irony...the robot cannot get enough water even though he is underwater.
Theme...In this video, everything the robot touches is withered or broken, so it is insisting that everything people do has an effect on environment.
