摘要： 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.

摘要： A robot lawn mower and computer implemented method is disclosed for distinguishing a type of feature in a lawn area. The method includes detecting a non-lawn feature in an upcoming path of the robot lawnmower, controlling the robot lawnmower to circumnavigate the non-lawn feature around a perimeter of the non-lawn feature, recording characteristics of the circumnavigation of the non-lawn feature, and distinguishing, based on the characteristics of the circumnavigation, a type of non-lawn feature as being either a boundary of a lawn area or a feature entirely contained within the lawn area.
