1. A method for detecting an unknown obstacle, comprising:
moving, by an autonomous mobile robot in response to a first distance from the autonomous mobile robot to an obstacle being less than a preset detection distance and a type of the obstacle being unknown, to a first position in a direction away from the obstacle, wherein a distance from the first position to the obstacle is not less than the preset detection distance, and the preset detection distance is greater than or equal to a focal length of a camera used for detecting the obstacle; and
detecting, by the autonomous mobile robot, the obstacle at the first position and navigating based on a detection result.
