摘要： The present invention relates to a non-contact obstacle-avoiding autonomous lawn mower, including a housing, a moving module, a drive module, and a control module. An ultrasonic sensor assembly is disposed on the housing. The ultrasonic sensor assembly includes at least two ultrasonic sensors, including a first ultrasonic sensor and a second ultrasonic sensor. When a distance between an obstacle detected by the ultrasonic sensor assembly and the autonomous lawn mower is less than a preset distance, the control module controls the autonomous lawn mower to execute a preset obstacle-avoidance measure. Compared with the prior art, the present invention uses an ultrasonic sensor to detect an obstacle and sets a preset distance to prevent the autonomous lawn mower from colliding with the obstacle, thereby implementing non-contact obstacle avoidance of the autonomous lawn mower.

摘要： A self-moving device and a control method for a self-moving device are disclosed. The self-moving device includes a moving module, a control module and an adjusting device. The moving module includes a track, driven by a drive motor to drive the self-moving device to move. The control module controls the adjusting device to adjust a grounding length of the track, such that the grounding length of the track when the self-moving device turns is smaller than that of the track when the self-moving device moves straightly. The control method for a self-moving device includes the steps: controlling to reduce the grounding length of the track before the self-moving device is controlled to turn; and controlling to increase the grounding length of the track after the self-moving device is controlled to finish the turning.

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.
