  • Patent number: 11256267
    Abstract: 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.

  • Publication number: 20200201347
    Abstract: The invention relates to a self-moving device, including: a housing, a movement module configured to drive the housing to move, a drive module configured to drive the movement module to move, and a control module configured to control the self-moving device. A non-contact obstacle recognition sensor assembly is disposed on the housing. After the obstacle recognition sensor assembly detects that an obstacle exists in a movement direction, the control module controls the self-moving device to continue moving and steer until the obstacle is avoided. The movement direction is a forward driving direction of the self-moving device.

  • Patent number: 10105838
    Abstract: An automatic moving device and a control method therefor. The automatic moving device comprises a battery pack providing power. The automatic moving device can work within a working area and automatically return to a charging station for charging. The control method comprises monitoring the power level of the battery pack; if the power level of the battery pack is less than or equal to a preset power level, initiating an action of returning the automatic moving device to the charging station; and after a preset time period, stopping the travel. By setting a preset time period simultaneously with initiating a return action, and executing a return action within the preset time period, the control method prevents damage to the battery pack from over-discharging caused by the automatic moving device continually returning, thus achieving the effects of protecting the battery pack and extending the life thereof.
