Abstract: Methods for utilizing virtual boundaries with robotic devices are presented including: positioning a boundary component having a receiver pair to receive a first robotic device signal substantially simultaneously by each receiver of the receiver pair from a robotic device only when the robotic device is positioned along a virtual boundary; operating the robotic device to move automatically within an area co-located with the virtual boundary; transmitting the first robotic device signal by the robotic device; and receiving the first robotic device signal by the receiver pair thereby indicating that the robotic device is positioned along the virtual boundary.
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 retractable cable assembly in use with an electrical charger, power adapter, or other power supply. A cable wound on a spool within the cable assembly housing may be extracted by manually pulling on the cable or pressing of a release switch until the desired length of the cord is drawn. As the cord is drawn a torsional spring rotatably coupled to the spool and located within the core of the spool is compressed. An engaged pawl-ratchet mechanism is used to keep the spool, torsional spring and cord in place during and after extraction of the cord until which time retraction of the cord is desired. Rotation or twisting of the housing lid or of the main housing of the retractable cable assembly housing disengages the pawl-ratchet mechanism, thereby freeing the spool and torsional spring. The compressed torsional spring within the core of the spool rotates immediately as it decompresses causing the coupled spool to rotate and retract the cable, thereby winding it back around the spool within the housing.

Abstract: A method for instructing operation of a robotic floor-cleaning device based on the position of the robotic floor-cleaning device within a two-dimensional map of the workspace. A two-dimensional map of a workspace is generated using inputs from sensors positioned on a robotic floor-cleaning device to represent the multi-dimensional workspace of the robotic floor-cleaning device. The two-dimensional map is provided to a user on a user interface. A user may adjust the boundaries of the two-dimensional map through the user interface and select settings for map areas to control device operation in various areas of the workspace.
Abstract: A schedule development method for a robotic floor-cleaning device that attempts to recognize patterns in user input to automatically devise a work schedule.
Abstract: Provided is a method and apparatus for combining perceived depths to construct a floor plan using cameras, such as depth cameras. The camera(s) perceive depths from the camera(s) to objects within a first field of view. The camera(s) is rotated to observe a second field of view partly overlapping the first field of view. The camera(s) perceives depths from the camera(s) to objects within the second field of view. The depths from the first and second fields of view are compared to find the area of overlap between the two fields of view. The depths from the two fields of view are then merged at the area of overlap to create a segment of a floor plan. The method is repeated wherein depths are perceived within consecutively overlapping fields of view and are combined to construct a floor plan of the environment as the camera is rotated.
