Abstract: This application describes a cleaning device and a steam control method. The cleaning device may comprise a power source, a steam generating device, and a controller. The steam generating device may comprise a steam boiler and a temperature sensor. The steam boiler may be electrically connected to the power source, and the temperature sensor can be used to measure the temperature of the steam boiler or internal liquid. The controller may be configured to control the output voltage of the power source to generate steam by heating the steam boiler.

Abstract: The present disclosure describes a ground cleaning device that comprises a ground brush, a main body, and a fan. The fan may be located inside the main body and may comprise an air inlet and an air outlet. The main body may comprise a main air outlet channel, a front air outlet channel, and a rear air outlet channel. One end of the main air outlet channel may be connected to a switching device, which has a first state and a second state. Based on the switching device being in the first state, the switching device may close the rear air outlet channel to disconnect the main air outlet channel from the rear air outlet channel. Based on the switching device being in the second state, the switching device may open the rear air outlet channel to connect the main air outlet channel to the rear air outlet channel.

Abstract: A gimbal and a gimbal control method are disclosed. The gimbal control method may include: acquiring attitude information of a gimbal; determining whether the gimbal is in a falling state based upon the attitude information; and when the gimbal is in the falling state, triggering a protection mode and controlling the gimbal to rotate to a set attitude. The set attitude may be an attitude at which the gimbal is not easy to be broken from falling, thereby reducing the probability of the gimbal being broken from falling.

Abstract: A gimbal control method, including: upon detecting that a gimbal including a rotation shaft structure enters a storage mode, rotating the rotation shaft structure to a set position to make the gimbal satisfy a preset storage form; and controlling the rotation shaft structure to remain at the set position for a preset duration.

Abstract: A handheld gimbal includes a handle, a stabilization assembly mounted at the handle and configured to carry a load, an inertial measurement unit configured to obtain an actual attitude of the load and an actual attitude of the handle, and a microcontroller connected to the inertial measurement unit and configured to determine an operation mode of the handheld gimbal and control rotation of the stabilization assembly according to the operation mode of the handheld gimbal, the actual attitude of the load, and the actual attitude, to cause the load to rotate to a desired attitude.

Abstract: A time-lapse imaging control method for controlling an imaging system, the imaging system including a gimbal and an imaging device, the imaging device being mounted on the gimbal. The control method including determining a target feature being tracked by the imaging device, and determining a time-lapse imaging parameter used by the imaging device for recording image data; driving the gimbal to drive the imaging device to move to track the target feature, causing the target feature to be positioned within a range in a preview image; and controlling the imaging device to record a plurality of frames of images including the target feature with the time-lapse imaging parameter.

Abstract: A method for obtaining an initial mechanical angle of an electric motor includes determining a mechanical state of the electric motor, determining an initial electrical angle of the electric motor according to the mechanical state, and determining the initial mechanical angle of the electric motor according to the initial electrical angle.
