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.
