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: A horizontally vibrating brush for an automated robotic vacuum to agitate carpet fibers and like materials in a horizontal rather than vertical plane to loosen debris during vacuuming without causing debris to become more deeply embedded.

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 vehicle collision avoidance system that utilizes signal emitters and receivers positioned around the periphery of vehicles to detect nearby vehicles. Upon detection of a nearby vehicle, the system may execute any of a variety of predefined responses based on the distance from the local vehicle to the detected nearby vehicle.

Abstract: Methods for minimizing redundancy of surface coverage of a workspace using a robotic device and a base station are presented, the methods including: creating a polar map of the workspace defined by a number of cells; creating a policy by dividing the workspace into a number of zones each defined by a portion of the number of cells and by ordering the number of zones for surface coverage; selecting a zone of the number of zones for surface coverage by the robotic device; creating a cell matrix of the portion of number of cells representing the selected zone; assigning the selected zone to the robotic device; covering the selected zone by the robotic device; reporting an actual zone coverage to the base station; updating a coverage matrix corresponding with the cell matrix of the selected zone to indicate coverage; and calculating a penalty.

Abstract: A method for enabling communication and collaboration between robotic device. Robotic devices exchange wireless signals to connect to one another and enter an authentication phase. After authenticating, robotic devices add new devices to a network containing all authenticated robotic devices. Robotic devices within a network may send or receive information or instructions to and from other robotic devices in the network. Robotic devices that are out of direct signal range of other robotic devices may communicate them via other robotic devices within the network that form a bridge to forward the signals to the intended target.

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: Methods for utilizing virtual boundaries with robotic devices are presented including: positioning a boundary component having a first receiver pair to receive a first robotic device signal substantially simultaneously by each receiver of the first receiver pair from a first robotic device only when the first robotic device is positioned along a first virtual boundary; operating the first robotic device to move automatically within an area co-located with the first virtual boundary; transmitting the first robotic device signal by the first robotic device; and receiving the first robotic device signal by the first receiver pair thereby indicating that the first robotic device is positioned along the first virtual boundary.

Abstract: A method for selecting routes for items being sent from a given beginning node to a given destination node within a network. Each segment of a trip is evaluated and assigned a negative reward based on the deviation from the ideal length of time to complete that segment. Upon arrival of the item at the destination node, the route is assigned a large positive reward. The system is configured to attempt to maximize rewards at all times by selecting the routes with the lowest likelihood of delay. As more and more trips are completed, the control system may define a policy that selects routes based on their probability of yielding the highest reward.

Abstract: A floor-cleaning system comprised of a mobile robot having compartments to hold modules corresponding to various functions and a base station storing extra modules. The mobile robot runs until one or more modules is expended, at which point the robot navigates to the base station, ejects expended modules, and loads new modules. The robot continues operation with a minimum amount of downtime and a reduced need for human intervention. The base station may be supplied with numerous ready modules so that a human administrator only needs to replenish, replace or empty the modules periodically.

Abstract: A method for an automated robotic wheeled device to overcome small obstacles, such as flooring thresholds, comprising a set of auxiliary ellipsoid or oval wheels that are engaged when the device detects that it is obstructed from moving forward. When the oval wheels are engaged, they turn and propel the device forward and upward so that it can effectively move over obstacles that would normally be too tall for the device to overcome.

Abstract: A method for instructing operation of a mobile automated robotic device through scannable targets printed with codes corresponding to programmatic instructions. Targets are strategically placed by users or administrators in a workspace in locations visible to the device through scanning. Devices are equipped with one or more scanners that continuously scan available surfaces for targets, executing the programmatic instructions corresponding to codes of identified targets.

Abstract: The present invention discloses a system for confining the movement of a robot such that certain area(s) are temporarily or permanently excluded from its working territory. The system uses light-absorbing, black-out paper stripe(s) capable of a complete absorption of light including infrared. The system also uses a mobile robot equipped with infrared emitters and infrared-reflection detectors that communicate the existence of infrared reflection or the lack of it to the robot's control unit. The control unit controls the wheel drivers and ensures that the robot continues travelling only as long as the reflection of infrared signals are detected from the surface onto which it is headed. In this system therefore, the said black-out papers act as a fence that the robot cannot pass because they prevent the reflection of infrared light from the spot(s) where they are placed and force the robot to stop and change directions when it encounters a black-out stripe.
