    Abstract: A control method includes, when a landing gear of an unmanned aerial vehicle (UAV) is at a zero position, controlling a yaw-axis motor of a gimbal of the UAV to rotate to different positions according to a specific strategy that includes the landing gear following the yaw-axis motor to rotate synchronously, determining an angle relationship parameter between a landing gear motor of the UAV and the yaw-axis motor by controlling the yaw-axis motor to rotate to the different positions, in a mode where the landing gear follows the yaw-axis to rotate, obtaining a real-time rotation angle of the yaw-axis motor, and controlling rotation of the landing gear motor according to the angle relationship parameter and the real-time rotation angle of the yaw-axis motor.

    Abstract: A gimbal camera includes a camera body, a camera main control board in the camera body, and an attitude-detection circuit in the camera body and independent from the camera main control board. The attitude-detection circuit is electrically connected to the camera main control board. The attitude-detection circuit includes an inertial measurement unit on one side of the attitude-detection circuit away from the camera main control board.

    Abstract: The present disclosure provides a load stabilization device, a control method thereof, and a computer readable storage medium. In the load stabilization device, a motion sensor, a processor, a stabilization motor, and a parallelogram mechanism constitute a closed-loop feedback control system. A control instruction for the stabilization motor is generated based on a velocity of a second end of the parallelogram mechanism in a direction of gravity relative to a ground, where the second end may carry a load, and the stabilization motor is controlled to drive, according to the control instruction, the parallelogram mechanism to rotate relative to a base, so as to at least partially offset or compensate for jitter of the load carried at the second end of the parallelogram mechanism in the direction of gravity, suppress disturbance generated at a first end of the parallelogram mechanism, and stabilize the load carried at the second end

    Abstract: An unmanned vehicle includes a body and a gimbal assembly arranged at the body. The body includes a bottom cover arranged at a bottom of the body. The gimbal assembly includes a shock-absorbing structure arranged inside the body and fixedly mounted at an inner bottom wall of the bottom cover, and a gimbal arranged outside the body and coupled to the shock-absorbing structure. The inner bottom wall is arranged inside the body and faces towards a top of the body.

    Abstract: A camera includes a housing, a lens assembly accommodated in the housing, a plurality of circuit boards accommodated in the housing and including a first circuit board and at least one second circuit board, and a connection rod including at least one step member at a peripheral of the connection rod. One end of the connection rod is configured to fix the lens assembly in the housing. Another end of the connection rod is configured to connect with the first circuit board. One of the at least one second circuit board abuts against a corresponding one of the at least one step member and is fixed to the connection rod. The plurality of circuit boards are spaced apart from the lens assembly and from each other.
