Movable apparatus control method, apparatus, device, and medium

An electronic device comprising a memory and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by one or more processors, a light emitting unit and a light receiving unit are disposed at a front end of a movable apparatus, and a distance between the light emitting unit and a bottom surface of the movable apparatus is greater than a distance between the light receiving unit and the bottom surface

• wherein the processor is configured to:
• monitor, by the light receiving unit, a light point cloud formed by light emitted by the light emitting unit during movement of the movable apparatus, the light point cloud being a point cloud formed by a light beam emitted from the light emitting unit towards a preset direction and irradiated an obstacle, and the preset direction being a direction toward a front of the movable apparatus and facing downward;
• and
• control the movable apparatus to decelerate in response to that the light point cloud satisfies a preset condition, the preset condition including the light point cloud being missing.
