Abstract: A method for gathering information about a work environment comprising using two laser rangefinders to obtain distances to two obstacles. A camera captures an image of the area and an image processor extracts the color depth at the two points of the laser rangefinders. The image processor then extracts the color depth of the line connecting the two points of the laser rangefinders. If the color depth of the two points of the laser rangefinders and the line connecting them is within a predetermined range, the system identifies the area as a substantially flat surface. When a substantially flat surface is found, the system can calculate the length and angle of the line connecting the two points of the laser rangefinders.

Abstract: A mopping extension attachable to a robotic vacuum. The mopping extension comprising, at minimum, a frame, a cloth, and a mechanism to secure the frame to the body of the robotic vacuum. The mopping extension may be installed in a dedicated compartment within the robotic vacuum body such that the cloth is dragged along the work surface as the robotic vacuum travels through the work area. In some embodiments, the mopping extension further comprises a means to automatically dampen the cloth to further improve cleaning efficiency. In some embodiments, the mopping extension further comprises means to move the mopping extension back and forth during operation to further improve cleaning efficiency. In some embodiments, the mopping extension further comprises a means to disengage and engage the mopping extension as the robotic vacuum is working.

Abstract: A method for automated mobile devices to identify and avoid dangerous edges or drop-offs. Rangefinder sensors are installed on the underside of devices to calculate distances to the work surfaces. Distances are monitored for changes greater than a predetermined threshold. Distance changes greater than the threshold cause the device to execute methods or algorithms for avoiding the identified area.

Abstract: A method for distance measurement is proposed in which two or more laser light emitters emitting converging collimated laser beams, an image sensor, and an image processor are positioned on a baseplate. The output of the laser light emitters from light points on surfaces substantially opposite the baseplate. The image sensor captures images of the projected light points. The area of the polygon or the length of the line resulting from connecting the light points is extracted by the image processor and compared to values in a preconfigured table relating polygon areas or line lengths to distances from the baseplate to surfaces.

Abstract: The present invention proposes a method for robotic devices to accurately identify authorized users. Biometric data of users is supplied to the system through biometric scanners. Biometric profiles of authorized users are identified to the system during an initial set-up phase. Subsequently, users provide biometric data to the system through the scanners in order to be authenticated. Received data is compared to the original stored profiles, and when a match is found, that user is authenticated. In another aspect of the invention, a time-activated memory storage process is utilized to prevent malicious attempts to overcome the authentication process. Memory cells become writable in successive time slots, after which point the memory cells are converted to read-only. If a user is authenticated during a particular time slot, their biometric data is written in the available memory cell. If no user is authenticated, the available memory cell is written with junk data.

Abstract: A system for compacting debris collected within a robotic vacuum debris container to allow more space for incoming debris. The volume of collected debris is reduced by pressure plates pressing the debris against surfaces so that the debris container may hold a greater mass of debris. The system allows robotic vacuums to operate for longer periods of time before requiring maintenance by a user to empty the debris container.

Abstract: A distance estimation system comprised of a laser light emitter, two image sensors, and an image processor are positioned on a baseplate such that the fields of view of the image sensors overlap and contain the projections of an emitted collimated laser beam within a predetermined range of distances. The image sensors simultaneously capture images of the laser beam projections. The displacement of the laser beam projection from a first image taken by a first image sensor to a second image taken by a second image sensor is extracted by the image processor. The displacement is compared to a preconfigured table relating displacement distances with distances from the baseplate to projection surfaces to find an estimated distance of the baseplate from the projection surface at the time that the images were captured.

Abstract: A method for increasing the rate of debris collection of a robotic vacuum through increasing the number of times a robotic vacuum's cleaning apparatus passes over a work surface during each pass of the device. The device's main cleaning apparatus is installed on a plate that rotates within the housing of the device. The drive unit is housed separately from the rotating plate so that the device's normal movement patterns will be uninterrupted by the rotation of the cleaning apparatus. Ideally, the cleaning apparatus will be caused to rotate two or more times over an area before the robotic vacuum has driven completely through the area.

Abstract: Methods for automated robotic movement for a robotic device using an electronic computing device are presented, the methods including: causing the electronic computing device to establish a working zone; measuring distances to all obstacles in the working zone thereby detecting all obstacles in the working zone; establishing a coverage path that accounts for all detected obstacles; executing the coverage path such the robotic device covers the working zone at least once; if a new obstacle is detected, establishing an adapted coverage path that accounts for the new obstacle; and executing the adapted coverage path. In some embodiments, methods further include: bypassing the new obstacle; and returning to the coverage path.

Abstract: The disclosure relates to a system and/or method to create or otherwise define one or more virtual barriers for confining or controlling an autonomous robotic device substantially within one or more portion of one or more selected working areas, for example, to prohibit entrance of certain areas. The system and/or method may use a set of beacon transmitters that emit time-stamped signals, which are received by one or more robots and used to calculate the robotic device's distance from such beacons.

Abstract: A spherical or ovoid design for a robotic vacuum in which the housing of the vacuum also serves as the means by which the device moves. Steering of the device is controlled by adjusting the center of gravity within the housing. Perforations in the housing allow debris to be vacuumed into the device.

Abstract: A robotic vacuum wherein the housing of the system is cylindrical in form with two wheels of diameter larger than the diameter of the housing supporting the housing on either end. Larger wheels permit the device to more easily travel over small bumps or obstacles and changes in elevation. Furthermore, the design requires less power to drive the housing, so more energy is available for the primary function of vacuuming.

Abstract: A method for instructing operation of a mobile automated robotic device through scannable targets printed with codes corresponding to programmatic instructions.
