  • Built in robotic floor cleaning system
    Patent number: 10958081
    Abstract: The present disclosure provides a built-in robotic floor cleaning system installed within the infrastructure of a workspace and a method for controlling and integrating such system in a workspace. The built-in robotic floor cleaning system comprises a robotic floor cleaning device and a docking station for charging the robotic floor cleaning device wherein the docking station is built into the infrastructure of the workspace. The system may further comprise a control panel integrated into the infrastructure of the workspace to deliver inputs from users and display outputs from the system. The system may further comprise a variety of types of confinement methods built into the infrastructure of the workspace to aid the robotic floor cleaning device in navigation. The system may also be provided with a virtual map of the environment during an initial set-up phase to assist with navigation.

  • Robotic floor cleaning device with motor for controlled liquid release
    Patent number: 10932640
    Abstract: A robotic floor cleaning device that features a controlled liquid releasing mechanism. A rotatable cylinder with at least one aperture for storing a limited quantity of liquid is connected to a separate motor designated specifically for operation of the controlled liquid release mechanism. There is a passage below the cylinder and between the cylinder and a drainage mechanism. The cylinder is within or adjacent to a liquid reservoir. Each time an aperture is exposed to the liquid within the reservoir it fills with liquid. As the motor operates the connected cylinder is rotated until the aperture is adjacent to the passage. The liquid in the aperture will flow through the passage and enter the drainage mechanism which disperses the liquid to the working surface. The release of liquid is halted when the connected motor stops operating.

  • Methods for finding the perimeter of a place using observed coordinates
    Patent number: 10935383
    Abstract: Provided is a method for navigating and mapping a workspace, including: obtaining a stream of spatial data indicative of a robot's position in a workspace, the stream of spatial data being based on at least output of a first sensor; obtaining a stream of movement data indicative of the robot's displacement in the workspace, the stream of movement data being based on at least output of a second sensor of different type than the first sensor; navigating along a path of the robot in the workspace based on the stream of spatial data; while navigating, mapping at least part of the workspace based on the stream of spatial data to form or update a spatial map in memory; and switching to a second mode of operation if the stream of spatial data is unavailable due to the first sensor becoming impaired or inoperative.

  • Edge detection system
    Patent number: 10933534
    Abstract: Included is a method for a mobile automated device to detect and avoid edges including: providing one or more rangefinder sensors on the mobile automated device to calculate, continuously or periodically, distances from the one or more rangefinder sensor to a surface; monitoring, with a processor of the mobile automated device, the distances calculated by each of the one or more rangefinder sensors; and actuating, with the processor of the mobile automated device, the mobile automated device to execute one or more predetermined movement patterns upon the processor detecting a calculated distance greater than a predetermined amount, wherein the one or more movement patterns initiate movement of the mobile automated device away from the area where the increase was detected.

  • Method and apparatus for combining data to construct a floor plan
    Patent number: 10915114
    Abstract: Provided is a process, including obtaining, with a robot, raw pixel intensity values of a first image and raw pixel intensity values of a second image, wherein the first image and the second image are taken from different positions; determining, with one or more processors, an overlapping area of a field of view of the first image and of a field of view of the second image by comparing the raw pixel intensity values of the first image to the raw pixel intensity values of the second image; spatially, with one or more processors, aligning values based on sensor readings of the robot based on the overlapping area; and inferring, with one or more processors, features of a working environment of the robot based on the spatially aligned sensor readings.
