This invention proposes a variable-speed dual-frame fan structure, comprising: an axial fan module, a dual-frame structure, a wing structure, and an electromechanical control module. The axial fan module includes fan blades, a fan motor, and fan support and protection components. The dual-frame structure includes two rotating shaft motors and the dual-frame structure components, with the two rotating shaft motors fixedly connected to the dual-frame structure components. The wing structure is connected at one end to the dual-frame structure via rotating shaft motors, and at the other end to the
robot's
fuselage. The electromechanical control module includes an electronic speed controller (ESC) for the fan motors and controllers for the two rotating shaft motors. The ESC controls the fan
motor speed, and the controllers control the rotating shaft motor angles. This invention enables the fan to generate thrust in any direction, thereby reducing the number of required motors while maintaining the
robot's
six degrees of freedom, optimizing the
robot's
circuit design, and reducing the robot's size to improve its movement agility.
