  • Autonomous lawn mower, self-moving device, and method for recognizing obstacle by same
    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.

  • SELF-MOVING DEVICE AND METHOD FOR CONTROLLING MOVEMENT PATH OF SAME
    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.
