A return method and device for an aerial vehicle are provided. The method includes: during a flight process of the aerial vehicle, performing real-time planning on a return path from a current position of the aerial vehicle to a return position; performing real-time transmission of the return path to a terminal device to display the return path on a display interface. The aerial vehicle plans the return path in real-time during flight and sends it in real-time to the terminal device for display. This allows users to timely understand the planned return path of the aerial vehicle. Even in the event of a loss of connection between the aerial vehicle and the terminal device, the terminal device can display the return path based on the previously received information, thereby enhancing the safety of aerial vehicle return.

A mobile object includes: a remaining energy amount acquisition unit that acquires the amount of energy remaining in the mobile object; and a range specifying unit that specifics, on the basis of the amount of energy remaining in the mobile object, a movement range in which the mobile object can return from the current position to the return position.

An underwater cleaning robot contains a movement device for moving the underwater cleaning robot under water, a cleaning device for cleaning an object located under water, a control device for controlling the movement device and/or the cleaning device and a communication device for receiving and/or transmitting signals from outside the underwater cleaning robot and vice versa. The communication device contains a first ultrasonic transducer for receiving ultrasonic signals transmitted under water and is designed to transmit electrical signals, corresponding to the ultrasonic signals received, to the control device.

An emergency module may determine the occurrence of an autorotation condition for a rotary wing air vehicle controlled by a user. The emergency module may, responsive to determining the occurrence of the autorotation condition, control the air vehicle to enter into an autorotation. The emergency module may perform one or more non-user actions during the autorotation to assist the user with the autorotation. The emergency module may, while performing the one or more non-user actions during the autorotation, allow the user to maneuver the air vehicle by interacting one or more control interfaces of the air vehicle.

An embodiment of the present invention provides an artificial intelligence cleaner comprising: a memory for storing a simultaneous localization and mapping (SLAM) map of a cleaning space; a travel driving part for driving the artificial intelligence cleaner; and a processor for collecting a plurality of cleaning records for the cleaning space, dividing the cleaning space into a plurality of cleaning areas by using the SLAM map and the plurality of collected cleaning records, determining a cleaning path of the artificial intelligence cleaner in consideration of the divided cleaning areas, and controlling the travel driving part according to the determined cleaning path, wherein when an abnormal situation occurs during cleaning on the basis of the determined cleaning path, the processor modifies the cleaning path by applying path simplification to a preconfigured area of the remaining cleaning area.

A mobile object management system is provided. The management system comprises an information processing device including an acquisition unit, an instruction generation unit, and a transmission unit. The acquisition unit is configured to acquire remaining level information indicating the remaining level of a battery. The battery is configured to store power that a charging station supplies to a mobile object. The instruction generation unit generates, on the basis of the remaining level information, instruction information for controlling the mobile object. The instruction information is information related to operations by the mobile object. The transmission unit is configured to transmit the instruction information to the mobile object, whereby operations by the mobile object are controlled.

A load handling device for lifting and moving containers stacked in a storage system having a grid framework structure supporting a plurality of tracks arranged in a grid pattern, the load handling device including: a wheel assembly driven by a drive mechanism; a lifting device for lifting a storage container; a position detection detector; and a controller configured to control movement of the load handling device by: a) determining a feedforward torque demand on the wheel assembly at a given time from a predetermined motion control profile; and b) compensating the feedforward torque demand from a measured position of the load handling device on the grid structure at the given time to calculate a torque demand on the wheel assembly.

A control method includes obtaining a current mission parameter of a current flight mission and historical flight data of a historical flight mission related to the current mission. The current mission parameter is related to an energy consumption of a current aerial vehicle performing the current flight mission, the historical flight data includes a historical mission parameter and a historical energy consumption in the historical flight mission, and the historical mission parameter is related to an energy consumption of a historical aerial vehicle performing the historical mission. The method further includes obtaining a current remaining power energy of the current aerial vehicle in real time, and determining whether the current aerial vehicle is able to reach a destination of the current flight mission based at least one on the current mission parameter, the historical flight data, and the current remaining power energy, to obtain a determination result.
