  • Patent number: 10551843
    Abstract: The present disclosure describes techniques for a robotic cleaning device to determine a plan to clean an environment based on types of surfaces in the environment. The plan can include a route to take in the environment and/or one or more configurations to apply to the robotic cleaning device during the route. Determining the plan can include inserting detected surface types into an environmental map of the environment. The environmental map can then be used on future routes such that the robotic cleaning device can know a surface type of a surface before the robotic cleaning device reaches the surface. In some examples, a type of a surface of the environment can be detected by the robotic cleaning device based on optical polarization of light.

  • Publication number: 20140223675
    Abstract: A floor-cleaning robot having a chassis for moving the floor-cleaning robot in a direction of travel over a surface to be cleaned, a cleaning implement, a control unit and first and second measuring devices for three-dimensional distance measurement. Each of the first and second measuring devices is configured to sense distance between the measuring device and a plurality of surface elements within a respective solid angle that is spanned from the measuring device. The first and second measuring devices are aligned in such a manner that the direction of travel runs through the first solid angle. The second solid angle is offset in relation to the first solid angle. The control unit is designed to generate and/or update a representation of the surface to be cleaned, on the basis of the distances from surface elements sensed by first and second measuring devices.

  • Publication number: 20140215731
    Abstract: Disclosed is mobile mechanical xeriscape gravel cleaner which is delivered to the site of the xeriscaping to be cleaned by a wheel/axle assembly, leveled with adjustable jack stands mounted on the metal frame. Xeriscape material to be cleaned is collected and deposited in a hopper with slide plate to control flow of material into the receiving chamber. Using an external power system, the auger/screener device rotation begins and picks up and carries forward the material, passing through the transition plate to the auger/cleaner chamber where foreign material passes through the screen. The cleaned material proceeds to the discharge chamber where it is collected and returned to the original xeriscaped site. The mobile mechanical xeriscape gravel cleaner can clean xeriscape gravel at a lower cost, with improved quality and a higher rate of speed than was previously possible, with significantly reduced burden to the ecosystem.

    Abstract: A method of cleaning an area using an automatic cleaning device may include receiving, from a video camera, information associated with an edge located on a surface, determining, by an automatic cleaning device, a position of the automatic cleaning device on the surface relative to the edge and using the received information to move the automatic cleaning device from the determined position along a path so that the automatic cleaning device cleans the surface along the path. The path may be substantially parallel to the edge, and the edge may be located a distance from a reference point on the automatic cleaning device during movement of the automatic cleaning device.
