The invention relates to the technical field of swimming apparatuses, and in particular to a wearable suit for free swimming. The wearable suit comprises a foot assembly, a body part assembly, an arm part assembly and a head assembly, wherein the foot assembly comprises boot-shaped parts which are worn in feet, a plate-shaped part in charge of implementing pushing in water, flexible connecting parts for connecting the boot-shaped parts and the plate-shaped part and fasteners which are arranged on the upper surfaces of the boot-shaped parts and are used for fixing and adjusting the flexible connecting parts. Since the foot assembly of the swimming suit provided by the invention comprises the boot-shaped parts and the plate-shaped part, a human body, under high counter-acting force formed by high resistance of the plate-shaped part and water, can slide towards a head side when two feet implement a flexion-extension action; the pushing plate (the plate-shaped part) is parallel to a driving direction and the pushing plate is horizontal when the two feet are retracted, and at the same time, the resistance is quite low, so that the human body can slide towards the head side easily and rapidly; and two hands are free, so that a user can regulate directions and can slowly stroke and play in the water with the two hands, with the two feet staying still.

The invention relates to a bionic fish, particularly relates to a free swimming bionic fish for detection, and solves the technical problem of providing the free swimming bionic fish for detection which is convenient for human life detection, high in flexibility and simple in structure. In order to solve the technical problem, the free swimming bionic fish for detection is provided. The free swimming bionic fish for detection comprises a supporting plate, a slide rail, a first spring, a gear, a first connecting rod, a circular rod, a slide block, a gear rack, a supporting rod, a fish body, a fixed pulley, a first pull line, a first swing rod, a second spring, a second connecting rod, a fish head, a detector, a second pull line, a first electric wheel, a third pull line, a second swing rod, a second electric wheel, a vacuum tube and a fishtail. The middle part of the left side outside the fish body is provided with the second connecting rod. The fish head is connected at the left end of the second connecting rod in a hinged way. The detector is arranged at the left side of the fish head. The supporting plate is arranged in the fish body. The effects that human life detection is facilitated, the flexibility is high and the structure is simple can be achieved.

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.
