  • Publication number: 20250121920
    Abstract: A biomimetic turtle includes a trunk, a head movably connected with a front end of the trunk in the front-rear direction, two front limbs disposed on a front section of the trunk and each rotatable relative to the trunk to sway in an up-down direction, and a driving module to drive the head and the front limbs. Each front limb has a curve-shaped rigid portion with a recess, and a deformable flipper portion engaged in the recess and extending rearwardly. With the deformable flipper portion deformed and bent during swaying of the front limbs, a forward propelling force is generated to propel the biomimetic turtle forwardly. The head is operably movable to vary the center of gravity of 10 the biomimetic turtle 100 in the water, and thus the front portion of the biomimetic turtle is inclined upwardly or downwardly to facilitate ascending or descending of the biomimetic turtle.

  • Publication number: 20250065743
    Abstract: A wireless charging method for charging an underwater moving device is implemented by a charging device. The charging device receives electricity from a cable, and includes a first underwater wireless communication unit, a position holding unit, a first control unit, and a wireless charging transmitter. The underwater moving device includes a second underwater wireless communication unit, a wireless charging receiver, and a rechargeable battery. The first underwater wireless communication unit obtains moving device information by communicating with the second underwater wireless communication unit. The position holding unit holds the underwater moving device at a charging location, and generates a positioning success signal after the underwater moving device is held at the charging location. Upon receiving the positioning success signal, the first control unit controls the wireless charging transmitter to charge the rechargeable battery based on the moving device information.

  • Publication number: 20250026019
    Abstract: A robot fish system includes a robot fish, and a light-emitting device emitting a light signal. The robot fish includes a housing, on which first and second light receivers, a driving module and a processor are disposed. The processor is connected to the first and second light receivers and the driving module. The processor controls the driving module to operate in a left-turn mode to make the robot fish turn left when only the first light receiver receives the light signal, in a right-turn mode to make the robot fish turn right when only the second light receiver receives the light signal, in a straight-moving mode to make the robot fish move straight when both the first and second light receivers receive the light signal, and in a random mode to make the robot fish move randomly when none of the first and second light receivers receives the light signal.

  • Publication number: 20250017199
    Abstract: A biomimetic waterfowl includes a housing, two waterfowl legs, and a driving module. The waterfowl legs are spaced apart from each other in a left-right direction and are mounted to a bottom portion of the housing. Each waterfowl leg includes a first segment mounted to the housing and rotatable about a first axis parallel to the left-right direction, and a second segment rotatable about a second axis parallel to the first axis. The driving module is mounted to the housing and is configured to drive the waterfowl legs. Each of the waterfowl legs is movable between a retracted state, where the first segment extends forwardly from the housing and the second segment extends rearwardly from the first segment, and a propelling state, where the first segment extends rearwardly from the housing and the second segment extends rearwardly from the first segment.

  • Publication number: 20250007333
    Abstract: A wireless charging system adapted to be implemented in an underwater environment is provided. The wireless charging system includes a wireless charging device and an underwater moving device. The wireless charging device is configured to magnetically attract and hold the underwater moving device in a charging position. The wireless charging device includes a wireless transmitting unit that is disposed therein. The underwater moving device includes a wireless receiving unit that is disposed therein and that corresponds to the wireless transmitting unit in position when the underwater moving device is held in the charging position. Wherein, when the underwater moving device is in the charging position, the wireless receiving unit and the wireless transmitting unit are aligned with each other, and the wireless charging system is configured to control the wireless transmitting unit to wirelessly transmit power to the wireless receiving unit so as to charge the underwater moving device.

  • Publication number: 20240417049
    Abstract: A biomimetic turtle device includes a trunk unit, a limb unit and a control unit. The control unit includes a water depth sensor which detects water depth where the biomimetic turtle device is, and a circuit module which receives the signal from the water depth sensor and determines if the biomimetic turtle device is at a target water depth position, wherein a driving mechanism or a weight adjusting mechanism is operated if the biomimetic turtle device is not at the target water depth position to vary the volume or weight of the trunk unit so as to adjust density of the trunk unit to thereby adjust a water depth position of the biomimetic turtle device.

  • Publication number: 20240417048
    Abstract: A biomimetic fish includes a cover structure and two housing bodies arranged in a front-rear direction, connected to each other, and rotatable relative to each other about a rotating axis that extends in an up-down direction. The cover structure includes first and second cover portions respectively formed on the housing bodies. The first cover portion has two distal end parts disposed at a distal end thereof and arranged in a left-right direction. The second cover portion has two arcuate outer surfaces respectively adjacent to the distal end parts and each having a center of curvature located on the rotating axis. At least one of the arcuate outer surfaces is connected to the respective one of the distal end parts. An intersection of the arcuate outer surfaces and the respective one of the distal end parts is located at an inner side of the respective one of the distal end parts.
