A device to moving a water shooter is described. The device may contain features that allow the device to travel submerged in a reservoir with a water shooter attached. The device may travel along a fixed track, rotational boom, or be free swimming in order to move the water shooter within the reservoir so that unique water effects may be achieved.

A method to hatch Artemia nauplii starting from an amount of Artemia cysts, including diapauzing cysts, by incubating the cysts in a hatching medium under conditions allowing at least a portion of the cysts to hatch and to release free swimming nauplii within a predetermined incubation period, in which method the cysts are brought in contact with a compound comprising at least one -(OH)C=C(OH)- structure, to break diapause in at least a number of said diapauzing cysts in order to enable them to produce free swimming nauplii within said predetermined incubation period thereby increasing the hatching percentage of the incubated cysts from X % of the total number of full cysts when the cysts are not brought in contact with said compound, to a hatching percentage higher than X % when they arebrought in contact with said compound.

The invention discloses a steering control system of a mini cable-free swimming robot. The steering control system comprises side fins positioned on two sides of a robot body and in hinged connectionwith the robot body, a piezoelectric ceramic pile driving the side fins, mini pressure sensors positioned on the side fins, mini photoelectric encoders positioned at positions where the side fins arehinged to the robot body, a single chip microcomputer controller and an inside radio frequency transceiver, and further comprises an external radio frequency transceiver, a single chip microcomputer main controller and a track recorder which are outside the robot body independently the single chip microcomputer controller and the inside radio frequency transceiver are positioned inside the robot body, the single chip microcomputer controller, the inside radio frequency transceiver, a driving power source and the piezoelectric ceramic pile are sequentially connected through leads, the single chip microcomputer controller is connected with the mini pressure sensors and the photoelectric encoders through leads, the outside radio frequency transceiver, the single chip microcomputer main controller and the track recorder are sequentially connected through leads, and the outside radio frequency transceiver and the inside radio frequency transceiver are in wireless signal connection. By the steering control system, steering of the swimming robot can be controlled flexibly, and the robot is stable in integral control performance and has practicability.

The invention discloses a miniature cable-free swimming robot which comprises head part, a fuselage and a tail fin, wherein the head part is arranged at one end of the fuselage, and the other end of the fuselage is fixedly connected with one end of the tail fin. The miniature cable-free swimming robot is characterized in that the head part and the fuselage are in hollow structures inside, the fuselage is internally provided with a piezoelectric ceramic stack, a micrometric displacement amplifying structure and lateral fins made of giant magnetostrictive thin film hyperbolic plates, all of which are symmetrically distributed, wherein the head part is internally provided with a radio frequency transceiver, and the lower part of the fuselage is internally provided with a drive power. With the adoption of the technical scheme, the miniature cable-free swimming robot makes main movement realizes highest work by depending on the external magnetic field, and realizes steering motion by depending on the drive device with low power consumption, and is simple in structure and long in time of endurance, thus having a very good practical value.
