    Abstract: An underwater robotic device includes a housing unit, a control unit and a propelling unit. The housing unit includes a base seat and an upper cover in liquid-tight engagement with the base seat. The control unit is disposed within the housing unit and includes a circuit module and a center-of-gravity transferring module which is electronically connected with the circuit module. The center-of-gravity transferring module has a movable weight member and a transfer driving mechanism which drives movement of the weight member so as to vary a position of a center of gravity of the underwater robotic device and to control downward and upward moving directions of the underwater robotic device in the water. The propelling unit is connected with the housing unit and is electronically connected with the control unit to produce a propelling force to move the underwater robotic device forward in the water.

    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.

    Abstract: A biomimetic aquatic device includes a housing, a driving module, a cam, and a weight unit. The driving module is disposed in a receiving space of the housing, and includes a driving shaft rotatable about its own axis. The cam is mounted co-rotatably to the driving shaft, and has a cam groove formed in an outer surface of the cam and having at least a portion that extends spirally about the axis. The weight unit is mounted to the driving module, is movable along the axis relative to the driving module, and includes an engaging member engaging and movable along the cam groove. When the driving shaft and the cam are rotated, the weight unit moves relative to the driving module along the axis via engagement between the engaging member and the cam groove, thereby changing a center of gravity of the biomimetic aquatic device.

    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.
