摘要： An automatic lawn mower including: a frame body; a movement module; a cutting module; a controller; a plurality of sensors, configured to detect an obstacle in an environment, where the plurality of sensors include: a plurality of first sensors, where the first sensors are arranged around the frame body in a manner in which a detection direction thereof is inclined upward by a first preset angle relative to a horizontal reference plane; and a second sensor, arranged in a manner in which a detection direction thereof is toward a front end of the frame body and is inclined downward by a second preset angle relative to the horizontal reference plane, where poses of first sensors and second sensor are combined, so that a sum of detection ranges of the plurality of sensors covers all angles in a direction parallel to the horizontal reference plane, thereby avoiding the obstacles.

摘要： The present invention provides an autonomous vehicle, comprising: a housing; a driving module, mounted on the housing; a limit detecting module, mounted on the housing and detecting a distance between the autonomous vehicle and a limit; an energy module, mounted on the housing and providing energy for the autonomous vehicle; a control module, electrically connected to the driving module and the limit detecting module, the control module enables to the driving module to execute steering according to a signal representing an angle relationship between the autonomous vehicle and the limit and sent by the limit detecting module, such that an acute angle or right angle is always formed between the central axis of the autonomous vehicle and one lateral side of the limit when the steering is finished, and an acute angle or right angle is formed between the central axis of the autonomous vehicle and another lateral side of the limit when the steering begins; and if judging that the driving of the autonomous vehicle meets a preset condition, then the control module reduces an upper limit of an angle value range of an acute angle or right angle formed between the central axis of the autonomous vehicle and one lateral side of the limit when the steering is finished. The efficiency of passing by a narrow passage is higher.

摘要： A self-moving device capable of automatically recognizing an object in front is provided. The self-moving device includes a signal transmission module, a gradient determination module, and a control module. The signal transmission module transmits recognition signals propagated along at least two different paths. The gradient determination module obtains, according to the recognition signals, a first determination result indicating whether an object in front is a slope. The control module controls a traveling path of the self-moving device according to the first determination result.

摘要： An automatic working system includes a self-moving device powered by an energy module and moving and working in a defined working area. The self-moving device includes a body, a movement module, a task execution module, a control module, and a charging system configured to store external electrical energy in the energy module to charge the energy module. The charging system includes at least two charging modes for charging the energy module. In the different charging modes, the charging system uses different charging logics and/or different charging parameters to charge the energy module. The charging system further includes a charging management module configured to manage the charging modes, to enable the charging system to use a corresponding charging mode to charge the energy module.
