  • Publication number: 20240118712
    Abstract: The present disclosure relates to a self-moving device, an obstacle avoidance control method, and a storage medium. In an embodiment, detection data of an obstacle in a moving direction of the self-moving device is obtained, and a distance to the obstacle is obtained through calculation according to the detection data of the obstacle, or a distance between the self-moving device and the obstacle obtained by another device according to the detection data is received. In response to determining that the distance between the self-moving device and the obstacle is between a first preset distance and a second preset distance, the self-moving device maintains an original moving speed and an original moving direction and moves forward stably. In response to determining that the second preset distance is reached, turning is performed at the original moving speed or a faster moving speed.

  • Publication number: 20240099187
    Abstract: The present disclosure relates to a self-moving device, a control method for avoiding obstacles, and a storage medium. In an embodiment, a distance to an obstacle can be determined through the self-moving device. The controller can pre-adjust the self-moving device to deflect by a certain angle to move before the distance between the self-moving device and the obstacle reaches a normal turning distance. In response to the normal turning distance being reached, the self-moving device is then controlled to turn.
