For example, while the AMD is stationary, the sensors used may include an accelerometer or a gyrometer. While the AMD is moving, data from time-of-flight sensors or one or more cameras may also be used. If the AMD is stationary low-level sensor thresholds are used. If the AMD is moving steadily, medium-level sensor thresholds are used. If the AMD is suddenly decelerating, high-level sensor thresholds are used.

  • Patent number: 11169533
    Abstract: A robotic cleaning device and a method at the robotic cleaning device of performing cliff detection along a surface over which the robotic cleaning device moves. The method includes illuminating the surface with at least one light source, capturing an image of the surface, detecting at least one illuminated section in the captured image, and determining distance to objects in the at least one illuminated section of the captured image. The method further comprises comparing at least two of the determined distances and detecting an object in the captured image as a cliff when cliff when a relation between the at least two compared determined distances complies with a predetermined increase criterion.
