Claim 10:
11. A mobile water delivery device for use during a performance of visual effects with a water reservoir having a water surface and floor at a substantially constant depth below the water surface, comprising:
an unmanned vehicle that operates without a human aboard and that operates according to a predetermined choreographed sequence during the performance, and that includes support legs that are positioned in a non-deployed position or a deployed position according to the predetermined choreographed sequence, that floats and is movable around the water reservoir when the support legs are in the non-deployed position, and that includes a guidance assembly that guides the unmanned vehicle according to the predetermined choreographed sequence;
a propulsion assembly for moving the unmanned vehicle without being fixed to another object or to the floor, and according to the predetermined choreographed sequence provided by the guidance assembly;
a nozzle for emitting a stream of water in a non-vertical direction according to the predetermined choreographed sequence; and
a water intake that supplies water to the nozzle;
wherein when the support legs are positioned in the deployed position, the support legs engage the floor so that the unmanned mobile water delivery device counteracts the force created by an emitted stream of water.
